Castalong
Remote guests,
straight into your stream.
Castalong brings your collaborators' cameras, screens and games right into OBS over WebRTC — switch them live, add on-screen titles, and run the whole show from one panel. No downloads for guests, no port-forwarding.
🎚️
Switch guests live
A vMix-style switcher — punch any guest's camera, screen or game to the program bus with a cut or fade.
🖥️
Cameras, screens & games
Guests share a webcam, a window, a whole screen or a game with audio — each becomes its own OBS source.
🏷️
On-screen titles
Customisable lower-thirds, centre cards and tickers — names appear automatically when you take a guest.
🧩
Lives inside OBS
Add the control panel as an OBS dock and the graphics as a browser source. Run everything without leaving OBS.

Use the link your host sent you — it opens the guest page and drops you straight into their room.
