Webinars that feel live — because they are.
STARCAST puts your speakers on a sub-second live stage and streams to thousands over a global CDN. Studio-grade production and a control room built like a broadcast desk.
Everything you need to run a real broadcast
Real-time interaction for your panel, rock-solid scale for your audience, and the production tools to make it look the part.
Sub-second live stage
Speakers and co-hosts join a real-time WebRTC stage — no 30-second delay, so conversation and Q&A feel natural.
Scales to thousands
Your audience watches an adaptive stream over a global CDN. 400 or 40,000, the quality holds and the box never breaks a sweat.
Studio production
Slides, lower-third overlays, standby screens, hold music, and bring guests on stage — all from one control panel.
Control room + green room
Line speakers up backstage, see everyone in multiview, cue the next segment, and go live with one click.
Registration & reminders
Branded registration pages and automated email reminders, so seats fill up and people actually show up.
Adaptive quality
Viewers on weak connections smoothly drop to a lower rung instead of buffering — every seat gets a clean stream.
