Proxim lets you ship multiplayer games without running any infrastructure and adds proximity voice chat that's spatialized to player positions in your world. Use either feature on its own, or combine them for a full peer-to-peer multiplayer experience with voice. Proxim is targeted for peer to peer games of about 4-12 players, not games with huge lobbies.
Players run the Proxim companion app alongside your game; your game talks to it through an SDK or the raw WebSocket protocol.
- Multiplayer without infrastructure — peer-to-peer networking handled by the Proxim app. No game servers to host, scale, or pay for.
- Proximity chat — spatialized voice that fades with distance, so players hear each other based on where they are in your game.
- Modular — wire up just networking, just voice, or both. The two systems are independent.

More engine SDKs are on the way. If your engine isn't listed yet, you can integrate directly against the protocol below.
For engines without an official SDK, modding runtimes, or manual testing, see raw-protocol.md. It documents the local WebSocket on ws://127.0.0.1:5656 and every message the companion app accepts and emits.
