Hey Product Hunt! 👋 I'm JAJA, the builder behind Syncast — and today's the day! The frustration was real: as an esport caster, you're constantly alt-tabbing between browser tabs to monitor multiple streams, losing focus right when the action happens. Existing tools either eat your bandwidth with RTMP relays or force you to install heavy software. So I built Syncast — a browser-based multiplex control room for esport casters. No install, no RTMP, no bandwidth overhead. Just open your browser and you're live. What it does: 🎮 Monitor 6 to 8 Twitch/Kick/YouTube streams simultaneously with SMPTE timecode and real-time signal indicators ⚡ One-click switch to push any source directly to your OBS output — without interrupting the other feeds 🌐 100% browser-based — works anywhere, zero setup Built for the casters who cover tournaments and need to stay sharp across every feed at once. I'd love to hear from the casters and esport orgs in the community — what's your biggest pain point during a live multiplex broadcast? — JAJA
