One codebase gives you the authoritative server, the game client, the map editor, the content pipeline, and packaging for desktop, mobile, and the browser — you bring the game: content, scripts, and rules live in your own repository that embeds the engine. In continuous development since 2006, the engine powers community multiplayer RPGs; a current example is Last Frontier, a post-apocalyptic MMO built on it. Why FOnline? - Multiplayer first. Not a single-player engine with networking bolted on: an authoritative server, replicated entity state, and client/server separation are the core design, all the way down to the entity model. - Complete vertical. Server, client, mapper, editor, resource baker, script compiler, test runner, auto-updater — all built from the same sources by one CMake pipeline. - Engine/game split that stays clean. The engine is a reusable submodule; your game owns content, scripts, configuration, branding, and release policy. Engine updates don't drag game policy with them. - Data-driven content. Prototypes, maps, dialogs, localization, and GUI are authored as plain-text assets and baked into runtime packs — friendly to diffs, reviews, and tooling. - Runs where players are. Native Windows/Linux/macOS, Android and iOS, and a WebAssembly client that plays in the browser over WebSockets.
