On Air
Run the show,
not the call.
STARCAST is a hybrid webinar platform — a sub-second WebRTC stage for your speakers, seamless HLS for an unlimited audience, wrapped in the calm confidence of a broadcast control room.
Sub-second stage
Speakers and promoted guests run on WebRTC — a real broadcast mesh, not a call grid.
Seamless audience
Passive viewers get adaptive HLS through a CDN. Unlimited scale, uninterrupted playback.
A real vision mixer
Six program layouts, preview/take, spotlight and lower-thirds — switch live with a clean dissolve.
One calm control room
Backstage rail, raised-hands queue, health panel. A non-technical host can run a 6-speaker show.
