Frequently Asked Questions
Everything you need to know about Multiplayer API.
What is Multiplayer API?
Multiplayer API is a cross-platform backend for multiplayer games. It provides player accounts, game rooms, matchmaking, leaderboards and realtime updates through a REST API and official SDKs for Unity, Java, .NET and C++.
Is Multiplayer API free to use?
Yes. There is a free plan with 128 MB storage, 1 game and up to 100 concurrent players. Paid plans (Standard and Pro) raise the limits for larger games. The source code and SDKs themselves are open source under MIT-0.
What license is the project released under?
The server source code and all SDKs are released under the MIT No Attribution (MIT-0) license. You can use, modify and distribute the code in any project — commercial or not — without giving attribution.
Which platforms and languages are supported?
Official SDKs exist for Unity (JsonUtility), Java (Jackson), .NET (System.Text.Json) and C++ (nlohmann::json). Any other platform can integrate directly through the language-agnostic REST API.
What features does the API provide?
Player registration and authentication, sessions and heartbeats, game data storage, game rooms with realtime actions, matchmaking lobbies with join requests and passwords, leaderboards, server time sync, and player moderation (timed and permanent bans).
Do I need to host my own server?
No. You can use the hosted service at api.michitai.com with a free developer account. Because the project is MIT-0 licensed, you may also self-host it — in that case your own deployment and privacy policy apply.
How do I get started?
Create a free account, generate an API token from your cabinet, then pick an SDK (Unity, Java, .NET or C++) or call the REST API directly. The API documentation includes copy-paste examples for every endpoint.
Where is my data stored?
The hosted service stores data on servers in Europe (France) provided by Hostinger, in compliance with GDPR. See the Privacy Policy for details on retention and your rights.
How do I report a bug or request a feature?
Contact support@michitai.com. You can also follow planned and completed work on the public development roadmap.
