Stream Overlay

Browser overlays on your screen

Borderless, transparent, click-through, always-on-top browser windows for streaming. For example, you can show your Twitch chat and alerts on your display, over your game.

I made this app because I would often not notice my chat messages on my other monitor, and I'd prefer to have them come up on the display I'm looking at, rather than only in an OBS overlay. It's also great for single monitor streamers.
