Nakama: realtime backend for games and apps with multiplayer, chat, leaderboards and storage
Nakama is an open source realtime backend for games and apps, made by Heroic Labs. It gives your client SDKs one server for user authentication, realtime multiplayer over WebSocket, a matchmaker, parties and chat, leaderboards and tournaments, friends and groups, and a flexible storage engine for player data. Server side runtime code in Lua, Go or JavaScript lets you add authoritative game logic, and a built in admin Console web UI lets you inspect players, storage, leaderboards, matches and live server status.
This cloudimg image runs Nakama 3.40.0 on Ubuntu 24.04 LTS as a single self contained Go binary, backed by a local PostgreSQL 16 database. Your game and app clients connect to the client API on port 7350, while the admin Console listens on the loopback interface behind an nginx reverse proxy on port 80, with WebSocket support and an unauthenticated health endpoint for Azure Load Balancer probes. The backend is migrated and ready the moment the instance boots.
The image is secure by default. Nakama normally ships several default secrets, including an admin Console login of admin and password and a client server key of defaultkey. On this image every one of them is regenerated uniquely on each instance's first boot: the Console username and password, the client server key, the session and runtime keys, and the PostgreSQL password. The defaults are rotated away and no longer work, and no secret is baked into the image or shared between deployments.
