Definition
An OBS Browser Source is a source type in OBS Studio that renders a live web page inside your streaming scene. It uses a built-in Chromium browser to load URLs, display interactive elements, and render web apps directly in your stream.
Browser Sources are used for alerts, overlays, chat widgets, and — via StreamTranslate — real-time translated subtitles.
How OBS Browser Sources Work
- OBS embeds a Chromium browser internally
- You provide a URL and dimensions (e.g. 1920×1080)
- The web page renders live and appears as a transparent overlay in your scene
- Web apps can communicate with OBS via JavaScript APIs
- Browser Sources update in real time — changes to the web app appear instantly
How StreamTranslate Uses Browser Sources
StreamTranslate gives you a unique overlay URL. You paste that URL into an OBS Browser Source. The page connects to StreamTranslate's AI translation service, listens to your microphone, and renders translated subtitles directly in your OBS scene — all in real time.
- No plugin installation needed — browser source is built into OBS
- Transparent background — subtitles overlay your game or camera
- Fully customizable position and styling via StreamTranslate dashboard
