🎙️ Streamer Overlay

5,900+ cards

Show any reference card on stream. Search below, check the preview — it renders exactly what the overlay shows — and push it. The overlay page is /obs, a transparent page made to be an OBS Browser Source; this panel drives it. Cards cover every entity on the site plus all story, harvest and study events with their options and rewards.

OBS setup
  1. Overlay: add a Browser Source in OBS with this URL (transparent background, suggested 460 × 800):
  2. Controls: in OBS, View → Docks → Custom Browser Docks…, add this page as a dock:

    The dock and the browser source share one browser profile inside OBS, so the panel drives the overlay directly — everything stays on your machine. (The overlay source keeps its transparency either way; it's the Browser Source that renders on stream, the dock is only controls.)
  3. Prefer controlling from your own browser? OBS's browser is a separate program that shares nothing with yours. Tick Remote session above — the overlay URL gains your private session code and pushes travel over a free public relay (ntfy.sh; only card ids are sent, each visitor gets their own random code). Off by default; with it off, nothing leaves your browser. Re-copy the overlay URL after toggling.
  4. Fully offline alternative: run make overlay-server (or node scripts/overlay_state_server.cjs) from the repo and add ?server to the Browser Source URL.
  5. Pin a card statically: /obs?id=UNIT_HOPLITE shows one card with no controls at all — handy for testing the look.
