fb is an open-source project for building and operating a 2D MMORPG game server.
It provides the server-side foundation for a persistent online game world—player sessions, in-game systems, and script-driven content such as quests, items, and NPC behavior. The stack is split into microservices (gateway, login, game, internal APIs, write-back, and supporting services) with Lua-driven game logic.
This repository contains server code and deployment tooling only. It does not include a game client or commercial game assets.
