obs-websocket

WebSocket API for OBS Studio.

Downloads

obs-websocket is now included by default with OBS Studio 28.0.0 and above. As such, there should be no need to download obs-websocket if you have OBS Studio > 28.0.0.

Binaries for OBS Studio < 28.0.0 on Windows, MacOS, and Linux are available in the Releases section.

Using obs-websocket

It is highly recommended to keep obs-websocket protected with a password against unauthorized control. obs-websocket generates a password for you automatically when you load it for the first time. To change this, open the "obs-websocket Settings" dialog under OBS' "Tools" menu. In the settings dialog, you can enable or disable authentication and set a password for it.

(Psst. You can use --websocket_port(value), --websocket_password(value), --websocket_debug(flag) and --websocket_ipv4_only(flag) on the command line to override the configured values.)

Possible use cases

• Remote control OBS from a phone or tablet on the same local network
• Change your stream overlay/graphics based on the current scene
• Automate scene switching with a third-party program (e.g. : auto-pilot, foot pedal, ...)
