04 / BEFORE THE ADVENTURE

Before you begin: a few questions.

Talk to us ↗
What kinds of games is Zekumo for?＋

Zekumo is designed for web games, WeChat mini games and small indie games. It provides authentication, saves, leaderboards, live operations and lightweight realtime interaction. Rooms support lightweight state sync; complex competitive games still need an authoritative game server designed for their gameplay.

Can I host it on my own server?＋

Yes. Zekumo includes a Docker Compose deployment setup and uses Go, PostgreSQL and Redis. Release artifacts can be stored locally or in S3-compatible storage. Follow the repository’s deployment guide to configure domains, secrets and the database before going live.

How can clients connect?＋

Official JavaScript / TypeScript and Go SDKs are available. Other languages and engines can use the HTTP API and WebSocket. Environments such as WeChat require adapters for their networking APIs; see the SDK documentation for details.

Is this a hosted cloud service? How do I get started?＋

Zekumo is an open-source backend you can host yourself. Deploy it using the quick-start guide, then create a game in the console to get an App ID. This website does not offer hosted plans or online service signup.
