We build our own apps and keep them running.
One developer in Amersfoort. One product, live since February 2026.
syncup.tv
Watch videos together, in sync. Create a room, share the link, and everyone sees the same frame of the same video — pause or skip and it happens for the whole room. Playback state travels over a WebSocket connection, so a pause reaches everyone without anyone refreshing. YouTube, Twitch, Kick and direct video links play in the browser with nothing to install, and a free extension for Chrome, Firefox and Edge adds the streaming services that keep their video behind DRM. Voice chat and screen sharing run over WebRTC, and your own video files stream straight from your device — they are never uploaded to a server.
