GTK Overlays

Browser-source overlay renderer. Load a show with:

/<userId>/<templateId>?chyron=1&header=1&up_next=1

Section flags (one per OBS source): chyron, header, up_next, host_1..3, video, slideshow, chat. Add ?demo=1 to show everything, ?single=<flag> to isolate one, ?fit=1 to scale to the window, ?eid=<episodeId> to pin a specific episode.
