OBS browser source overlay for animated stream mascots
StreamRio gives streamers a transparent browser-source overlay URL for animated mascots that react to Twitch and TikTok LIVE viewer events inside OBS, Streamlabs, TikTok Live Studio, and similar tools.
One URL for your stream scene
Copy the StreamRio overlay URL into OBS as a browser source and position the mascot wherever it fits your layout.
Transparent animated characters
Use browser-ready transparent video reactions so the mascot can sit naturally over gameplay, camera, or chat scenes.
Works with Twitch and TikTok LIVE
Connect platform events to rules, then let viewer actions drive the animations while your OBS scene stays simple.
From viewer event to mascot reaction
StreamRio is built around browser-source overlays, so the same setup works in OBS, Streamlabs, TikTok Live Studio, and other tools that can load a web source.
Create your StreamRio overlay
Choose a mascot and confirm the idle and reaction animations you want available.
Copy the browser-source URL
Open the dashboard and copy the overlay URL generated for your StreamRio scene.
Add a Browser Source in OBS
Paste the URL into OBS, set the source size, and keep the background transparent.
Test reactions before going live
Use Test Reaction to confirm the mascot, text bubble, and event rules display correctly in your OBS preview.

Does the mascot overlay have a transparent background?
Yes. StreamRio uses transparent character video assets so the mascot can appear over your existing scene without a boxed background.
