Contribute from OBS
Install the free Symphony plugin on a desktop or laptop, compose with normal OBS sources, and send that canvas to another OBS user running the same plugin.
Remote contribution, built for OBS
Symphony
Many contributors.
One production.
Keep the OBS workflow you already know. Symphony lets desktops, laptops, phones, and tablets send complete audio and video canvases to one host, where every contributor becomes an independent OBS source.

How Symphony works
Everyone builds their part. The host builds the show.
A contributor arranges a camera, browser, application, microphone, images, or other sources into one canvas. Symphony sends that finished canvas to the host—not to a streaming platform. The host places it in OBS alongside every other contributor and publishes the final production.

Use the standalone Symphony Mobile app to compose on a phone or tablet and connect to an OBS host through the plugin.
Direct the final production
The host independently positions, crops, filters, mutes, hides, mixes, or removes every Symphony source inside OBS.
Use the combination you need
Mobile is optional. The plugin stands on its own.
Three desktops can connect using only the free plugin. A phone or tablet joins through Symphony Mobile. Mixed sessions work the same way: each contributor delivers one independently controlled source to the host.
