leaf
A game server framework in Go (golang)
A modular Go framework for building online game servers, handling player connections, message routing, and multi-core load distribution so you only write game logic.
Leaf is a game server framework written in Go. A game server framework is a set of reusable building blocks that handles common backend tasks for online games, such as managing player connections, routing messages between clients and the server, and keeping the server running reliably under load. Using a framework means you write the game-specific logic while the framework handles the lower-level plumbing.
The README is very short and lists four characteristics: easy to use, reliable, multicore support, and a modular structure. Multicore support means the server can spread work across multiple CPU cores, which matters for games with many simultaneous players. Modularity means you can include or exclude pieces of the framework depending on what your game needs.

Where it fits
- Build the backend server for a multiplayer mobile game that handles hundreds of simultaneous player connections.
- Prototype a real-time online game server quickly by plugging in only the Leaf modules your game needs.
- Scale a game server across multiple CPU cores without writing custom concurrency code.
- Replace a slow single-threaded game backend with a multicore Leaf server to handle more players.
