As answered by people managing TurnKit and CodeSandbox.
TurnKit's answer
Indie game devs and studios.
TurnKit's answer
Basic relay just forwards messages. TurnKit Relay enforces turns, hides hands and has enforces voting result (end game, skip turn on illegal move as voted by clients).
TurnKit's answer
Speeds up development overall, adds security over basic relay and skips infrastructure and headache of building your own server. It is specifically built for turn based games while competition targets any game.
TurnKit's answer
I built many times as a freelancer multiplayer turn games for clients and it was taking too much time, but simple relays were too insecure and hacking even in unpopular games would break them fast. This was a solution I used to build games on top of and give clients faster results.
TurnKit's answer
Its powered by modern Java 25 backend with Spring making it engine agnostic. Also provided is a Unity SDK and general docs for other engines to implement their own SDK.
TurnKit's answer
We just launched, looking for devs to try it. Biggest customer are some of my games built for clients.
