What do people build with it?

USE CASE 1

Build the backend server for a multiplayer mobile game that handles hundreds of simultaneous player connections.

USE CASE 2

Prototype a real-time online game server quickly by plugging in only the Leaf modules your game needs.

USE CASE 3

Scale a game server across multiple CPU cores without writing custom concurrency code.

USE CASE 4

Replace a slow single-threaded game backend with a multicore Leaf server to handle more players.

In plain English

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. Documentation is available in both Chinese and English through tutorial files in the repository. The project is licensed under the Apache License 2.0, which allows free use and modification as long as the license notice is kept.

Copy-paste prompts

Prompt 1
Using the Leaf game server framework in Go, show me how to define a new message type and register a handler that broadcasts that message to all connected players.
Prompt 2
Help me set up a Leaf server that manages player sessions: players connect, get a unique ID, and get removed from the session map when they disconnect.
Prompt 3
I want to build a real-time chat room inside a Leaf game server. Walk me through creating the module, registering the message router, and broadcasting chat messages to all players in a room.
Prompt 4
Show me how to structure a Leaf project so that game logic, networking, and database access are in separate modules that can be enabled or disabled independently.
Prompt 5
Using Leaf's multicore support, how do I distribute player message processing across 4 CPU cores without creating race conditions in shared game state?
