You keep building your scenes in OBS. Corneta receives that signal on your Windows PC and sends it to the platforms you pick (Twitch, YouTube, Kick or any RTMP server), with the chats in one place. You can set the quality per platform and record the stream with its chat to watch later. With drop protection on, a BE RIGHT BACK screen keeps the stream up if OBS crashes. Free and open source (MIT), no account needed. Each platform uses your own upload.
