I've been there—trapped by vendor lock-in. You start with Firebase, everything works great, then bills climb and your game's future

is tied to someone else's ecosystem. PlayFab, Beamable—suddenly you're stuck.

With FastAPI For Unreal, that changes.

This plugin connects you to GBEngine—a completely open-source, self-hosted backend YOU control. Your data is yours. No vendor

lock-in. No surprise bills.

Why You'll Love This

The backend is intentionally minimal (~600 lines of clean Python). No bloat. Want to add features? It's simple. Want to modify how

data is stored? You own the code—no black boxes.

100% Open Source and Free

Every line is yours to fork, modify, and deploy on your servers.
