OpenFUT

Offline Ultimate Team — like SPT, but for FIFA 23.

OpenFUT replaces EA's retired FUT servers with a fully offline, single-player backend. You own FIFA 23 legitimately. You just want to keep playing after EA shut down the servers.

Core is game-independent. It speaks a clean REST API and knows nothing about FIFA 23 internals.

Bridge is FIFA-specific. It speaks FIFA 23's wire protocol and translates it into Core API calls. Bridge is where all reverse engineering work happens.

Design Principles

• Offline-first. No EA account required. No internet connection needed.
• Single-player only. This is not a multiplayer server emulator.
• Data-driven. All cards, packs, SBCs, and objectives are JSON files. Everything is moddable.
• Clean architecture. Core has zero knowledge of FIFA 23. Bridge has zero game logic.
• No copyrighted assets. No real player images, no EA trademarks in data files.
