obs-websocket

obs-websocket is the WebSocket control interface for OBS Studio, enabling external applications to monitor and control OBS remotely. It lets developers build tools that change scenes, control streaming or recording, manage sources, adjust inputs, read status information, and automate production workflows. The plugin is included by default in OBS Studio 28 and newer, so most modern OBS users do not need a separate installation. It exposes a structured request, response, and event protocol that can be used by dashboards, stream decks, bots, automation scripts, remote controllers, and broadcast systems. obs-websocket is especially useful for streamers, developers, live-event teams, and studios that need programmable control over OBS. It turns OBS from a manual desktop tool into an automation-ready production engine.
