Server runtime
Server-authoritative execution. The backend owns runtime state and validates actions through the engine’s contracts.
Gessa provides a server-authoritative runtime. Player clients submit actions and render the resulting state; the backend owns execution and validation. Build your game’s rules on this shared foundation.
Server-owned state
The backend is the source of truth, not the client.
Server-side validation
Actions are validated on the server, so the server decides what happened.
No backend to build
The authoritative loop comes with the engine, ready to run.
