Two-repo monorepo for an offline FUT backend inspired by SPT. openfut-core: game-independent REST API backend (Axum, SQLite, SQLx) - 19 API endpoints: auth, profiles, clubs, cards, packs, squads, objectives, SBCs, match rewards, NPC market, statistics - JSON-driven card/pack/objective/SBC data (fully moddable) - SQLx migrations, weighted pack generator, SBC validation engine - 5 integration tests passing openfut-bridge: FIFA 23 traffic proxy + reverse-engineering scaffold - Catch-all HTTP proxy with request capture to captures/ - Known-route mapper (FUT paths → Core API calls) - Placeholder responses for unknown endpoints - Admin endpoints: captures, unknown endpoint list - 4 unit tests passing cargo fmt ✓ cargo clippy -D warnings ✓ cargo test ✓ Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
OpenFUT Bridge
FIFA 23 integration layer and reverse-engineering proxy.
OpenFUT Bridge sits between the FIFA 23 client and the internet. It intercepts all FUT API traffic, logs every request, and routes known endpoints to OpenFUT Core. Unknown endpoints receive safe placeholder responses so the client keeps running.
What it does
- Transparent HTTP proxy — point FIFA 23 here instead of EA's servers
- Logs every request (method, path, headers, body, timestamp) to
captures/ - Maps known FUT endpoints to OpenFUT Core API calls
- Returns placeholder JSON for unknown endpoints (prevents client crashes)
- Admin API for reviewing captures and identifying unmapped routes
- Foundation for building the full FIFA 23 integration

Quick Start
# Run Core first
cd ../openfut-core && cargo run
# Run Bridge
cargo run
# Or with config
CORE_URL=http://127.0.0.1:8080 BRIDGE_LISTEN_ADDR=127.0.0.1:8443 cargo run

/_bridge/captures |
All captured requests |
GET |
/_bridge/unknown |

Reverse Engineering Workflow
- Point FIFA 23 at the Bridge (see
docs/setup-notes.mdfor proxy setup) - Start a game session
- Check
captures/or/_bridge/unknownfor new endpoints - Document the endpoint in
docs/endpoint-map.md - Add a mapping in
src/mapper.rs - Implement the Core handler
Proxy Setup (Research Notes)
See docs/setup-notes.md for notes on:
- Windows
hostsfile redirection - RPCS3 network config (PS3)
- Certificate bypass approaches
- mitmproxy integration
