Challonge vs Skillz

Challonge is competition management software for organizers handling registration, tournament progress, and records. It offers more than 25 formats, including single and double elimination, round robin, Swiss, and Grand Prix. Tournament pages can bring together brackets, participants, standings, sponsor details, stations, discussions, and score reporting. Event tools cover paid or unpaid tickets, registration fees, analytics, and attendee check-in; communities can host tournaments, events, contests, announcements, statistics, and Elo leaderboards. Applications can use its API to create tournaments and report scores. Paid registration runs through Stripe. The free Standard plan supports unlimited tournaments, events, and communities, up to 256 participants per tournament, and charges a $0.75 per-order Challonge fee on paid registrations. Premier is $83.88 a year, billed annually, and supports up to 512 participants, with no Challonge registration fee. Both plans limit single-stage Round Robin tournaments to 40 participants. Brackets can be embedded on websites; Premier adds custom themes and priority support. Challonge is available on web and through an API.

Skillz is a multiplayer tournament platform for mobile games where players compete for cash or virtual in-game currencies. Its formats include head-to-head matches, tournaments, brackets, and leaderboards. Skillz says its system matches players of similar skill levels to support fair opportunities. Players can join for free, enter free tournaments, or join cash tournaments starting at $0.60. Cash competitions are restricted to people aged 18 or older in regions where cash play is enabled. Skillz also serves independent game developers seeking to add social competition to their games. The developer SDK supports Unity, native iOS, and Android integrations, including direct Apple and Google API integrations; Unity SDK APIs can also support browser games hosted on Skillz. SIDEkick lets developers test supported integration workflows in the Unity editor without connecting to Skillz servers. Current requirements list Unity 2021.3 or 2022.3 LTS, iOS 14 or later, and Android API level 24 or later. Some features are unavailable on web, including brackets, real-time tournaments, chat, progressive leagues, and some payment methods.
