How it works

  • Using the livestream's URL, ChallaChat will make a connection and monitor the chat.
  • Messages are processed locally and appear in the overlay. This is secure and private; the chat data never leaves your computer.
  • Add the overlay endpoint as a Browser Source to any streaming software.
  • The overlay's appearance can be customized, and messages are rendered with full styling (emotes, badges, avatars, donations, subs, and more).
  • Multiple livestream connections (across multiple different streaming platforms) can be added to the same session, keeping all messages visible in one place.
