Real-time video dubbing requires a browser with good support for tab audio capture, an MV3 extension API, and WebRTC or WebSocket for streaming. Not every browser has all three. Here's the current state.
Fully supported
- Google Chrome — fully supported, this is where we test.
- Microsoft Edge — fully supported, same Chromium base.
- Brave — fully supported, no issues.
- Opera — fully supported, no issues.
- Arc — fully supported.
Partial support
- Firefox — works in beta via Firefox Add-ons. DRM-protected streams (Netflix, Disney+) sometimes need a flag. We'll publish a stable Firefox release in Q3 2026.
- Safari (macOS) — Apple's extension API is restrictive; we don't currently ship a Safari extension. There's a community-maintained wrapper but it's not officially supported.
Mobile
- iOS — no Safari extension support for tab audio capture. We don't ship iOS support yet.
- Android — Chrome for Android supports extensions in some configurations, but tab audio capture is unreliable. Use desktop for the best experience.
Why we focus on Chromium
Three reasons: (1) Chrome, Edge, Brave, Opera and Arc together represent about 75% of the desktop browser market in 2026. (2) Chromium's MV3 extension API has the cleanest support for tab audio capture. (3) Building for one engine lets us ship features faster. Firefox is our next priority.
