What Proxim is
Proxim is a free Windows desktop companion for proximity voice chat and serverless multiplayer in PC games. It targets small peer-to-peer games with 4–12 players rather than games built around dedicated servers. Voice is positioned by player location, so audio fades with distance. The app handles peer-to-peer networking without requiring game servers and supports voice and game-data relay plus a WebRTC handoff for direct game connections. Games can integrate through an SDK or the raw WebSocket endpoint documented at ws://127.0.0.1:5656. The listed engine SDK supports Godot, with more planned. Players create accounts with an email and password, generate join codes, and use them for rooms. A tray app controls microphone levels, output device, and player audio. Proxim is in Alpha, is made by solo developer Ryan Remer, and is free while scalability is evaluated.
