Corneta
Free local multistreaming for Windows with unified chat and replays
Corneta is a free, open-source Windows app for local multistreaming. Receive video from OBS or another RTMP encoder and send it to Twitch, YouTube, Kick, and custom RTMP/RTMPS destinations.
Manage supported platform chats in one view, set quality per destination, crop for vertical output, monitor connections, and configure a BRB fallback. Optionally record locally and revisit broadcasts with synchronized chat replay.
