Twitch overlay with animated virtual pet alerts
StreamRio turns follows, subscriptions, raids, Bits, channel rewards, and chat into animated character reactions inside your Twitch stream overlay.
Reactions for key Twitch moments
Map follows, subscriptions, raids, cheers, and other Twitch events to mascot reactions that match the energy of the moment.
Preview before you stream
Use Test Reaction in the dashboard to check timing, animation style, and text bubbles before your overlay goes live.
Transparent overlay URL
Add StreamRio as a browser source and keep the animated mascot layered over gameplay, camera scenes, or intermission screens.
