Every weekend, thousands of amateur tournaments get organized on top of three pieces of software most players never think about: start.gg, Challonge, and Battlefy. A local fighting game meetup, a Discord Valorant ladder, a university Rocket League league, and even portions of officially sanctioned esports circuits all run their brackets through one of these three tools. Yet the businesses behind them look nothing alike in September 2026. start.gg spent four years owned by Microsoft’s Xbox division before splitting off as an independent company and switching to a transaction-fee model. Challonge has stuck with a flat monthly subscription since 2009. Battlefy, a 14-year-old private company out of Vancouver, still won’t publish its prices at all.
That divergence matters more than it sounds. Picking the wrong bracket platform can mean losing a cut of every entry fee you collect, hitting a participant cap mid-signup, or discovering your community’s match history is locked inside a tool with no export path. This comparison breaks down what each platform actually charges, what it supports, and which one fits a given tournament size, budget, and game.
Why Bracket Software Became Critical Infrastructure
Competitive gaming has grown far past the point where a spreadsheet and a whiteboard bracket can keep up. The top of the esports pyramid now moves serious money: the Esports World Cup closed its 2026 edition with a record $75 million prize pool, spread across dozens of titles and hundreds of qualifying events that all had to be seeded, scheduled, and tracked somewhere before a single player ever touched a controller on the main stage. Every one of those qualifiers needed bracket software underneath it, and the vast majority of that infrastructure runs on exactly the three platforms compared here.
The stakes are smaller but no less real at the grassroots level. A weekly local tournament that mishandles seeding, loses a match report, or can’t process a $10 entry fee reliably loses the trust of the players who show up in person. That’s the layer where start.gg, Challonge, and Battlefy actually compete for attention, since none of the three currently market themselves as the infrastructure behind eight-figure prize pools the way a dedicated publisher platform might. What they do control is the day-to-day plumbing that decides whether a Tuesday-night Discord ladder or a monthly regional qualifier runs smoothly.
What These Platforms Actually Do
start.gg, Challonge, and Battlefy all solve the same core problem: turning a list of registered players or teams into a working single-elimination, double-elimination, round-robin, or Swiss-format bracket, then tracking match results as they come in. Beyond that shared foundation, the three products have grown in different directions.
None of the three are game engines, matchmaking services, or anti-cheat providers. They sit one layer above the actual game client, handling the administrative side of competition: who’s playing whom, in what order, on which stream slot, and who advances. That distinction matters when evaluating them, because a bracket platform’s job is coordination and record-keeping, not detecting whether a player cheated mid-match or verifying that a submitted score is accurate. Organizers still need separate tools, moderators, or publisher-side systems for that layer of integrity.
start.gg leans hardest into the fighting-game community (FGC) and grassroots esports scene, with player profiles, seeding tools, and event discovery built around the recurring local-tournament circuit that Smash Bros, Tekken, and Street Fighter communities run every week. Challonge stays closer to a pure bracket utility: create a tournament, embed the bracket on a website or Discord announcement, and manage the whole thing through a lightweight interface that has barely changed its core layout in over a decade. Battlefy positions itself as a broader competitive-gaming platform, covering everything from casual community brackets to larger sponsored events, though its current feature depth is harder to verify publicly than the other two.
The practical difference shows up the moment money changes hands. Free and casual brackets work similarly across all three. Paid entry fees, participant caps, and API access are where the platforms genuinely split, and that split is the core of this comparison.
start.gg: From Smash.gg to Independent Platform
start.gg was originally launched as Smash.gg, a name still recognized across the fighting-game community. Microsoft acquired the platform in 2021 and folded it under the Xbox umbrella, a move that briefly made an obscure bracket tool part of one of the largest gaming companies on the planet. That arrangement ended in early 2025, when start.gg announced it was “returning to its roots as an independent company,” thanking Microsoft and Xbox for their support while confirming it would keep operating as a self-service esports platform rather than a Microsoft product.
The independence came with a new business model. Instead of a subscription, start.gg now charges a platform fee of 6 percent on paid online registrations, added on top of the attendee’s total rather than deducted from the organizer’s payout. The fee applies specifically to online payments processed through providers like Stripe or PayPal; cash and on-site payments at physical venues are not subject to it. Free tournaments, which make up a large share of grassroots FGC events, incur no platform fee at all. start.gg’s own updates page also confirms an expanded Stripe integration that now supports Google Pay, Apple Pay, and more than 20 additional regional payment methods, a change aimed at organizers running events outside North America and Western Europe.
This fee-per-transaction structure is fundamentally different from a flat monthly subscription. For an organizer running one $10-entry local tournament a month with 40 players, the 6 percent fee amounts to roughly $24 total, well under what a Challonge Premier subscription would cost across the same period. For an organizer running weekly $25-entry events with 200 players, the math flips, and the transaction fee starts adding up faster than a flat monthly rate would.
start.gg’s game coverage stretches well beyond Super Smash Bros, even if that’s the community most associated with the Smash.gg name historically. Current listings on the platform span Street Fighter 6, Tekken 8, Guilty Gear Strive, and a long tail of regional and community-run titles that never show up in mainstream esports coverage but still need a place to seed a 64-player Saturday bracket. That breadth is a direct legacy of the platform’s grassroots FGC origins, where a single regional organizer might run five different fighting games out of one weekend venue and needs one login to manage all of them.
Challonge: The Veteran Bracket Tool
Challonge is the oldest of the three, founded in 2009 and backed early on by Techstars. Its pricing has stayed close to the same two-tier structure for years: a free, ad-supported Standard plan and a paid Premier plan. As of September 2026, Standard tournaments are capped at 256 participants and carry a $0.75 Challonge service fee on every paid order, on top of whatever the payment processor charges. Premier raises that ceiling to 512 participants, strips out the advertising, drops the $0.75 per-order fee, and adds priority support, larger 25MB match-file attachments, and one free Pro Community License.
Premier runs $12 per month billed monthly, or an effective $6.99 per month when billed annually, according to multiple current 2026 pricing trackers including itechguides.com and mycup.me. Additional Pro Community Licenses beyond the one bundled with Premier cost $14.99 per year, or $1.99 per month, for organizers running multiple simultaneous communities under one account.
Challonge changed its developer API terms in 2026. The current documentation confirms that free API usage is capped at 500 requests per month, with a grace period for existing integrations that ended on July 6, 2026. Beyond that limit, applications receive a 429 “Too Many Requests” response unless the account is upgraded to a paid tier. That’s a meaningful shift for Discord bots and community sites that auto-pull bracket data, since a busy weekly tournament with live embeds can burn through 500 requests quickly.
Because Challonge doesn’t specialize in any single genre, it shows up across an unusually wide range of communities: League of Legends amateur ladders, Rocket League 3v3 cups, Smash Bros side events that don’t use start.gg, tabletop and card-game tournaments, and even non-gaming brackets for office pools and local sports leagues. That generalist positioning is both its main selling point and the reason it lacks the genre-specific tooling, like start.gg’s pools system, that a more specialized platform can justify building.
Battlefy: The Quiet Vancouver Incumbent
Battlefy is the hardest of the three to pin down on hard numbers, and that opacity is itself part of the story. Company records place Battlefy as a 14-year-old private company headquartered in Vancouver, British Columbia, still listed as an independently operating business as of September 2026 with no public evidence of a shutdown or acquisition. Unlike start.gg and Challonge, Battlefy does not publish a pricing page with tiers, dollar figures, or participant caps that reviewers can independently verify, which is why several current comparison sites list its pricing simply as “not published.”
That doesn’t mean Battlefy is inactive. The platform continues to market itself around tournament creation, match management, and competitive-gaming discovery, and it remains a name organizers searching for Challonge or start.gg alternatives run into regularly. But for anyone comparing hard costs before committing a community’s tournament history to a platform, Battlefy is the one where you’ll need to contact sales or sign up directly to get a real number, rather than relying on a published rate card the way you can with Challonge or start.gg’s transaction-fee terms.
Full Specs Comparison: start.gg vs Challonge vs Battlefy
The table below lines up the verifiable specifications for all three platforms as of September 2026. Fields marked “not published” reflect a genuine gap in publicly available information rather than an oversight in this research.
| Category | start.gg | Challonge | Battlefy |
|---|---|---|---|
| Founded | Launched as Smash.gg; acquired by Microsoft/Xbox 2021, independent again since early 2025 | 2009 | Private company, ~14 years old |
| Headquarters / ownership | Independent company (formerly Xbox-owned) | Independent, Techstars-backed | Vancouver, British Columbia, Canada; private |
| Pricing model | 6% platform fee on paid online registrations | Flat monthly/annual subscription | Not publicly published |
| Free tier | Free for events with no paid registration | Standard: free, ad-supported, 256 participants | Free tier reported to exist; limits not published |
| Paid tier price | 6% added to attendee total on paid online entries only | Premier: $12/mo, or $6.99/mo billed annually | Not published |
| Participant cap | No published hard cap | 256 (Standard) / 512 (Premier) | Not published |
| Cash/on-site payments | No platform fee applied | N/A (processor fees still apply) | Not published |
| Per-order service fee | None beyond the 6% platform fee | $0.75 (Standard only; removed on Premier) | Not published |
| Developer API | Available; used for event and bracket data | Free up to 500 requests/month, paid required above that since July 6, 2026 | Not publicly documented |
| Primary community focus | Fighting games (FGC) and grassroots esports | General-purpose brackets across any game | General competitive gaming |
| Payment processing | Stripe, PayPal, Google Pay, Apple Pay, 20+ regional methods | Stripe integration | Not published |
| Bracket embeds | Yes | Yes, including themed embeds on Premier | Reported, not independently verified |
Two patterns stand out immediately. First, Challonge is the only one of the three with a transparent, independently confirmed price. Second, start.gg’s decision to charge nothing on free events and cash payments makes it structurally cheaper for the huge share of grassroots tournaments that never touch a credit card.
Pricing Breakdown: Subscription vs Transaction Fee
The single biggest decision an organizer makes when picking a bracket platform in 2026 is whether they’d rather pay a predictable flat fee or a variable cut of registration revenue. These two models produce very different totals depending on how many paid entries a community runs.
| Scenario | start.gg (6% on paid entries) | Challonge Premier ($12/mo or $6.99/mo annual) |
|---|---|---|
| Free weekly tournament, 30 players, no entry fee | $0 | $6.99–$12/mo regardless of entries |
| One $10-entry event/month, 40 players ($400 collected) | ~$24/month | $6.99–$12/mo flat |
| Weekly $15-entry events, 60 players ($900/week, ~$3,600/mo) | ~$216/month | $6.99–$12/mo flat |
| Large monthly event, 500 players at $20 entry ($10,000 collected) | ~$600 for that event | $6.99–$12/mo flat (if under Premier’s 512-participant cap) |
The crossover point is clear: for organizers collecting more than roughly $115 to $170 in paid registration per month (the range where the 6 percent fee equals $6.99 to $12), a flat Challonge Premier subscription becomes the cheaper option. Below that threshold, and especially for organizers running mostly free community events with the occasional paid entry, start.gg’s transaction-fee model wins by charging nothing when there’s nothing to charge against.
Because Battlefy doesn’t publish pricing, it can’t be slotted into this comparison with confidence. Organizers evaluating Battlefy specifically for cost reasons should treat the “not published” listing as a signal to get a quote directly rather than assume either model applies.
Bracket Formats and Tournament Structures Compared
All three platforms support the tournament formats that cover the overwhelming majority of competitive gaming events: single elimination, double elimination, round robin, and Swiss-style pairing. Where they differ is in the depth of multi-stage tournament support and how much manual setup a complex bracket structure requires.
Challonge’s current public API documentation explicitly states that its API does not support two-stage tournaments, meaning organizers who want a group stage that feeds into a separate elimination bracket need to manage that transition manually through the web interface rather than automating it through the API. That’s a real limitation for larger events with pool play followed by playoffs, a format common in Valorant and Overwatch community leagues.
start.gg’s fighting-game roots show up in its pools-and-bracket structure, which is built specifically around the common FGC format of splitting a large field into pools, running round robin or double elimination within each pool, then advancing top finishers into a top-cut bracket. This structure is baked into the product rather than bolted on, since it mirrors how offline FGC majors have run for over a decade.
Documentation for Battlefy’s specific format support is limited publicly, which makes it difficult to confirm whether its multi-stage tournament tools match either competitor’s depth without creating a test account and running a live event.
API, Discord, and Developer Integrations
For community organizers who run a Discord server alongside their tournaments, live bracket updates posted automatically into a channel are close to a must-have feature at any real scale. Here’s how the API access compares heading into late 2026.
Challonge’s REST API documentation is the most thoroughly documented of the three, with endpoints for creating tournaments, managing participants, and reporting match scores programmatically. The catch is the new rate limit: 500 free requests per month, enforced since July 6, 2026, after which further calls return an HTTP 429 error unless the account carries a paid plan. For a Discord bot that checks bracket status every few minutes during a live event, that ceiling can be exhausted in a single tournament day.
curl -X GET "https://api.challonge.com/v1/tournaments.json"
-H "Accept: application/json"
-d "api_key=YOUR_API_KEY"
# Response includes tournament objects with:
# id, name, url, state, participants_count,
# started_at, tournament_type, progress_meterstart.gg also exposes an API used by third-party Discord bots and community dashboards, though its documentation is oriented more toward event discovery and player data than toward the granular bracket-editing endpoints Challonge offers. No specific free-tier request limit for start.gg’s API was confirmed in current documentation, which makes direct comparison difficult beyond noting that both platforms support programmatic access in some form.
Battlefy’s current API and Discord-bot documentation could not be verified through public sources as of September 2026, which is consistent with the platform’s broader pattern of keeping technical and pricing details out of public view compared to its two competitors.
Discord itself sits underneath a lot of this integration work, since most tournament communities coordinate check-ins, match calls, and disputes through a Discord server regardless of which bracket platform holds the actual data. That dependency has gotten more complicated as Discord rolled out stricter identity checks; the platform’s new Account Signal age-verification system skips ID checks for roughly 90 percent of users by relying on account-behavior signals instead, but organizers running tournaments with real money on the line, or events open to minors, still need to think through how Discord-side verification interacts with whatever registration and age gates the bracket platform itself enforces.
Streaming and Broadcast Integration
A bracket that isn’t visible to spectators loses most of its value for anything beyond a private ladder. All three platforms support embedding a live, auto-updating bracket on an external website, which organizers typically pair with a stream overlay pulling the same data. None of the three run their own video streaming infrastructure, so the actual broadcast still happens on Twitch, YouTube Gaming, or Kick, with the bracket platform feeding match status and up-next information into chat bots or overlay software rather than hosting video itself.
start.gg’s event pages double as a spectator hub in a way Challonge’s don’t as strongly, listing stream links, commentary assignments, and station numbers alongside the bracket itself, a layout that traces back to how FGC majors have organized their setup areas for years. Challonge’s embeds are more minimal by design, favoring a clean bracket widget that a community can drop into any website template without extra chrome around it. Battlefy’s spectator-facing tools could not be independently verified for this comparison.
Anti-Cheat and Competitive Integrity
None of the three bracket platforms function as anti-cheat systems, and that’s worth stating plainly since organizers sometimes assume otherwise. A bracket tool tracks who won a reported match; it has no visibility into whether the underlying game session was clean. That job falls to the game’s own anti-cheat layer, and cheat detection rates have been climbing across the industry through 2026 as publishers invest more heavily in kernel-level and server-side detection.
What bracket platforms can do is provide the dispute-resolution scaffolding around a cheating accusation: match history, submitted scores, and timestamps that a tournament admin can reference when a player reports foul play. Challonge’s match-attachment feature, which lets participants upload screenshots or short clips as evidence up to 25MB on Premier, is the most direct nod to this need among the three. start.gg’s structured match-reporting flow inside its pools system serves a similar purpose, giving admins a paper trail without requiring a separate ticketing tool.
What Reviewers and Organizers Report
Independent reviews from software-comparison sites tracking these platforms through 2026 converge on a few consistent points worth weighing alongside the raw specs.
Clutch’s Best Online Tournament Platforms in 2026 comparison, evaluating platforms across tournament formats, registration and payments, live brackets, mobile experience, and community features, lists Challonge’s Premier tier at the same $6.99-per-month annualized rate and Standard at free with a 256-participant cap, matching the pricing confirmed elsewhere. The same tracker flags that Challonge’s mobile experience trails newer platforms, since its interface was originally built desktop-first and its dedicated mobile app hasn’t seen major updates in recent years, pushing most mobile users toward the browser version instead.
A separate bracket-maker roundup echoes that assessment of Challonge’s interface, describing it as aged and confirming that a mobile app exists but has seen limited development, while still recommending the platform for fast, no-frills bracket creation in esports and amateur sports settings alike.
Mycup.me’s tournament-software pricing guide, comparing subscription and pay-per-event pricing models across the category, independently reaches the same conclusion documented above about Challonge’s entry price: free for 256 participants with ads, $12 monthly or $6.99 monthly billed annually for the ad-free 512-participant Premier tier. That three-source agreement across itechguides.com, Clutch, and mycup.me is about as close to a verified price as third-party software pricing gets, since none of the three appear to be syndicating from a single shared source.
The table below cross-checks the three sources directly against each other on the specific numbers that matter most to a budget-conscious organizer.
| Data point | itechguides.com | Clutch | mycup.me |
|---|---|---|---|
| Challonge Standard participant cap | 256 | 256 | 256 |
| Challonge Premier participant cap | 512 | Not restated | 512 |
| Challonge Premier price (annual, per month) | Not published on-site, third-party confirmed | $6.99/month | $6.99/month (billed annually) |
| Challonge Premier price (monthly billing) | Not directly stated | Not directly stated | $12/month |
| Standard tier advertising | Ad-supported | Ad-supported | Not restated |
The agreement on the 256/512 participant caps across all three independent trackers is what makes this comparison confident rather than speculative. Where the sources diverge slightly is in how they present the monthly-versus-annual framing, though the underlying $6.99 annualized rate and $12 monthly rate both show up consistently once each source’s presentation is normalized.
Real-World Use Cases: Which Platform Fits Which Event
The right platform depends heavily on what kind of event is actually being run. These five scenarios cover the situations organizers most commonly ask about.
A weekly local fighting-game meetup with $5 pot-bonus entries. start.gg is purpose-built for exactly this. The pools-into-bracket structure matches how FGC locals have always run, entry fees under $10 mean the 6 percent fee is a few cents per player, and the platform’s player-profile system tracks head-to-head history across events automatically, which matters to communities that care about seeding.
A Discord community running a free monthly 1v1 ladder. Challonge’s free Standard tier covers this without hesitation, since there’s no entry fee to tax and the 256-participant cap comfortably covers most Discord server tournament turnouts. The ad-supported interface is a minor tradeoff for a $0 tool.
A university esports club running a semester-long league with sponsorship money. This is the scenario where Challonge Premier’s flat $6.99-to-$12 monthly rate usually wins over start.gg’s transaction fee, assuming the club is collecting real registration revenue across multiple events per month rather than one-off entries. The 512-participant cap on Premier also comfortably covers most collegiate league sizes.
A charity gaming marathon with a single large paid bracket. A one-off high-dollar event, such as a $10,000-pot Smash tournament, is where start.gg’s per-transaction model can add up fast, since 6 percent of a large one-time pot is a meaningful dollar figure. Organizers running this kind of event should run the math against a Challonge Premier month before committing, since the flat rate could be dramatically cheaper for a single large event.
A game publisher or brand running a sponsored, white-labeled competitive circuit. None of the three platforms compared here specialize in white-label deployment the way some publisher-facing tools do; that’s a different tier of the market entirely, aimed at studios needing a fully branded, self-hosted competition platform rather than a bracket tool bearing the vendor’s own name. Organizations at that scale typically move past consumer bracket tools altogether.
A regional fighting-game major with on-site console stations and arcade sticks. This is start.gg’s home turf, and it’s also where hardware choice starts to matter for the event itself. FGC majors typically standardize on a shared pool of controllers at each station, and organizers picking gear for that purpose are choosing between the same category of premium fight-focused controllers covered in recent head-to-head controller testing. The bracket software and the physical setup are separate decisions, but both get planned together when a major is scaling past a few dozen entrants into the hundreds.
Migration Guide: Moving Between Platforms
Switching bracket platforms mid-community is a common enough need that dedicated export guides exist for it. The core challenge is the same regardless of direction: rosters, seeding history, and match records live inside each platform’s own data model, and none of the three offer a one-click migration tool to move directly into a competitor.
Step 1: Export your current roster. Challonge allows CSV export of participant lists through its web interface. start.gg exposes player and event data through its API, which third-party tools can query to pull registration lists. Battlefy’s export options are not clearly documented publicly, so organizers should confirm export capability with support before assuming a migration path exists.
Step 2: Preserve seeding and standings history separately. None of the three platforms carry historical standings across a platform switch automatically. Organizers who care about season-long rankings should export standings as a spreadsheet before migrating, since that history won’t follow the roster import into a new platform.
Step 3: Re-create the bracket structure on the new platform. Because Challonge’s API doesn’t support two-stage tournaments while start.gg’s pools system does, organizers moving from Challonge to start.gg for a pools-based format may actually gain functionality, while organizers moving the other direction need to plan how to replicate pools-into-bracket manually inside Challonge.
Step 4: Update Discord bot integrations and embed links. Any Discord bot pulling live bracket data via API needs to be reconfigured to point at the new platform’s endpoints, and organizers should test the new integration against Challonge’s 500-request monthly cap, if migrating there, before relying on it during a live event.
Step 5: Communicate the switch to your community early. Player accounts, saved payment methods, and tournament history don’t transfer automatically. Giving a community at least one full event cycle of notice before switching avoids confusion during registration for the first event on the new platform.
One migration path worth flagging separately: organizers running mostly free events on Challonge who start collecting entry fees for the first time often reconsider start.gg at that exact moment, since the transaction-fee model means there’s no cost to trial it against a real paid event before committing a whole community’s history to a full switch. Running one event in parallel on both platforms, before decommissioning the old one, is a low-risk way to compare the actual registration experience side by side rather than relying on spec sheets alone.
Security and Data Ownership
Every registration collected through any of these three platforms includes at minimum a player’s display name, and typically an email address and, for paid events, payment information processed through a third-party provider like Stripe or PayPal rather than stored directly by the bracket platform itself. Challonge and start.gg both document their reliance on established payment processors rather than handling card data in-house, which is the standard, lower-risk approach for a small software company rather than a payments-focused business.
Data portability is the bigger practical concern for most organizers, not security in the breach sense. None of the three platforms guarantee that a community’s full multi-year match history remains exportable in a clean format indefinitely, which is why the migration guidance above recommends exporting standings as a standalone spreadsheet on a regular cadence rather than treating the platform as a permanent archive. Battlefy’s lack of published export documentation makes this a bigger unknown for organizers on that platform specifically.
Pros and Cons
start.gg
Pros: No cost for free events or cash payments; purpose-built pools-and-bracket structure for FGC-style events; broad payment method support including Apple Pay and Google Pay; large existing player base and event history in fighting games; independent ownership after the Microsoft/Xbox period removed uncertainty about long-term platform direction.
Cons: 6 percent fee can outpace a flat subscription for high-volume paid events; no published flat-rate alternative for organizers who’d prefer predictable monthly costs; API request limits for third-party integrations are less clearly documented than Challonge’s.
Challonge
Pros: Transparent, independently verified pricing; predictable flat monthly cost regardless of entry volume; well-documented API for developers; free tier covers most casual community brackets at 256 participants; general-purpose format works for any game, not just fighting games.
Cons: No API support for two-stage tournaments; mobile experience lags behind newer platforms; 500-request monthly API cap can be limiting for active Discord integrations; $0.75 per-order fee on the free Standard tier stacks on top of payment-processor charges.
Battlefy
Pros: Still actively operating after 14 years as an independent company, suggesting stability; broader competitive-gaming positioning beyond a single genre.
Cons: No published pricing, participant caps, or API documentation makes it impossible to budget or plan integrations with confidence before signing up; harder to independently verify feature claims compared to its two competitors.
Which Platform Should You Choose?
Choose start.gg if you’re running fighting-game locals, majors, or any event built around a pools-into-bracket format, especially if most of your events are free or low-entry-fee. Choose Challonge if you want a predictable flat monthly cost, need solid API access for a Discord bot or website embed, and don’t need multi-stage tournament automation. Choose Challonge Standard specifically if your tournaments are free or informal and stay under 256 participants. Choose start.gg specifically if entry fees are collected mostly through cash at physical venues, since that traffic avoids the 6 percent fee entirely. Evaluate Battlefy directly with their sales team if neither of the other two fits your game or community style, but budget extra time to get pricing and technical answers that aren’t published anywhere public.
The Verdict
For most organizers reading a comparison like this one in September 2026, the decision comes down to start.gg versus Challonge, since Battlefy’s lack of published data makes it difficult to recommend with confidence for anyone doing real cost planning. Between the two, there’s no universal winner: it’s a direct tradeoff between a transaction fee that scales with revenue and a flat subscription that doesn’t.
The numbers say this clearly. At roughly $115 to $170 in monthly paid registration revenue, the two pricing models cost about the same. Under that line, start.gg’s 6 percent fee model wins, especially for free or cash-heavy events. Over that line, Challonge Premier’s flat $6.99-to-$12 monthly rate is the cheaper option, and it stays cheaper no matter how large the paid registration volume grows. Fighting-game organizers get additional value from start.gg’s purpose-built pools structure regardless of the cost math, while general-purpose community organizers running any other game are usually better served by Challonge’s simpler, format-agnostic bracket tool. For events at either platform’s outer edge, especially large paid tournaments, running the math against your own expected entry volume before the first paid registration opens is worth the ten minutes it takes.
Frequently Asked Questions
Is start.gg still owned by Microsoft or Xbox in 2026?
No. Microsoft acquired the platform, then known as Smash.gg, in 2021. start.gg announced its return to independent ownership in early 2025, confirming it would continue operating as a self-service esports platform outside Microsoft and Xbox.
How much does Challonge Premier actually cost per month?
Challonge Premier costs $12 per month when billed monthly, or an effective $6.99 per month when billed annually. This is confirmed consistently across multiple independent 2026 pricing trackers.
Does start.gg charge fees on free tournaments?
No. start.gg’s 6 percent platform fee applies only to paid online registrations processed through providers like Stripe or PayPal. Free events and cash or on-site payments at physical venues are not subject to the fee.
What is Battlefy’s pricing?
Battlefy does not publish pricing tiers, participant caps, or plan names on a public rate card the way Challonge and start.gg do. Organizers who need firm numbers should contact Battlefy directly rather than rely on third-party estimates.
Can Challonge handle a two-stage tournament with group play followed by playoffs?
Challonge’s current public API documentation states that its API does not support two-stage tournaments. Organizers needing that structure through the API should evaluate whether the web interface can accommodate it manually or whether a different platform better fits the format.
What is Challonge’s current API rate limit?
As of a grace period that ended July 6, 2026, Challonge’s free API tier is limited to 500 requests per month. Requests beyond that limit return an HTTP 429 error unless the account is upgraded to a paid plan.
Which platform is best for fighting-game tournaments specifically?
start.gg is the strongest fit for fighting-game communities, since its pools-into-bracket structure was built around how FGC locals and majors have traditionally run events, and it carries the deepest existing player history in that scene as the successor to Smash.gg.
Do any of these platforms offer a mobile app?
Challonge has a mobile app, but independent reviewers report it has seen limited recent development, and most users manage brackets through a mobile browser instead. Current, verified mobile app details for start.gg and Battlefy were not established in available public documentation.
Can I export my tournament data if I switch platforms later?
Challonge supports CSV export of participant rosters through its web interface, and start.gg’s API can be queried by third-party tools to pull registration and event data. Battlefy’s export capabilities are not clearly documented publicly, so organizers should confirm directly with the platform before relying on a migration path.
Do bracket platforms handle anti-cheat or match integrity themselves?
No. start.gg, Challonge, and Battlefy manage registration, seeding, and bracket progression, not in-game cheat detection. That responsibility sits with the game’s own anti-cheat systems and with human tournament administrators reviewing disputed match reports.
