Stream Any Tab to Your Sonos. Instantly.
High‑quality, low‑effort casting from Chrome to Sonos with automatic frame sync, dynamic visuals, and optional premium stereo up to 320 kbps.
Built Like a Native Sonos Experience
Household & Device Selection
Choose any household or device quickly—perfect for multi‑room setups.
Automatic Video Sync
Frame sync measures device delay & aligns playback to remove perceived AV lag.
Dynamic Color Matching
UI adapts its background based on the active tab for a cohesive look.
Dark Mode & Theming
Designed for low‑light comfort without sacrificing contrast.
Rich Player Presence
Artwork + logo appear within Sonos app for a unified playback surface.
Full Transport Control
Play, pause, volume—from either extension or Sonos app.
The extension runs a lightweight capture + encode pipeline and cleanly integrates with your Sonos session. Visual adaptation and frame sync logic are isolated so regular browsing stays fast.
Getting Started Fast
- Install the extension from the Chrome Web Store.
- Open any audio or video site (YouTube, podcasts, web players).
- Click the Cast to Sonos icon and select your device.
- Playback starts—adjust volume or frame sync in options.

Your Privacy, Engineered In
Secure Sign‑In

One‑Click Reset
Right‑click → Options → Clear data. Instantly revoke keys via Sonos account.
Optional Front‑End Scripts
Disable UI adaptation for maximum minimalism—performance impact is already negligible.
