What Proxim is

Proxim is a Windows desktop companion for proximity voice chat and serverless multiplayer in PC games. It is aimed at small peer-to-peer games with 4–12 players, rather than games designed for dedicated servers. Voice audio is positioned according to players’ locations, fading as they move farther apart. Proxim handles peer-to-peer networking without requiring game servers to host or scale, and supports voice and game-data relay as well as a WebRTC handoff for direct game-to-game connections. Games can integrate through an SDK or a raw WebSocket protocol documented at ws://127.0.0.1:5656. The listed engine SDK is for Godot, with additional engine SDKs planned. Players create accounts with an email and password, generate a join code, and use it to enter a room. The tray app provides controls for microphone levels, output device, and player audio before a game starts. Proxim is in Alpha; its maker describes testing with friends and people he knows. The Free Alpha plan costs nothing while the maker evaluates scalability. The SDK is MIT-licensed, and the protocol is described as open.
