One browser source shows your whole overlay — you don't add a source per widget.
- In the overlay editor, open the brand menu (the GridCast mark, top-left) and find Browser Source Links.
- Copy Live channel, or Preview (this theme) to test an unpublished overlay.
- In OBS, choose Add → Browser, paste the link, and set the width and height to your overlay's canvas size. In Meld Studio, add a browser layer the same way.
Links include a private key (?k=...), so treat them like a password. Links copied before August 2026 don't have one and need pasting again.
