OBS is a free open source application that most Twitch and Youtube streamers use to do their thing. My web app is intended to function as a window capture outside of OBS. The user overlays the window capture over their streaming scene and matches chroma key colors between apps for a transparent background. Then they can activate games, tools, effects, and audio from Streamboy's control panel to enhance their streams.
I named the app Streamboy and added convenience features like hotkeys to make it easier to use. I intend to write documentation and open the app up to allow anyone to use, but that's a work in progress. Shout-out to Luke VanTrieste for the original games, QA help, and some creative direction.
