What we build
  • CastBrowser app icon

    CastBrowser

    Send web video to your television.

    • Android
    • iOS

    A browser for Android and iOS that finds the video on a page and plays it on your TV — Chromecast, AirPlay, Roku, Fire TV, smart TVs, and even a games console through its own browser.

    • CastBrowser playing a web video on a television while the phone shows the same page

      Browse any site, tap cast

    • The CastBrowser device list showing Chromecast, Roku, Samsung, Apple TV and Fire TV targets

      Every device on one list

    • A video stream going straight to the television while the phone shows its lock screen

      Direct cast, not mirroring

    • CastBrowser playback controls on a phone driving a video on a Roku Streaming Stick

      Play, pause, seek, volume

More in development. Everything we ship

How we got here

15 years of building software, spent mostly on the difficult parts.

Native mobile, web, desktop, and the streaming and media plumbing underneath all three. We learned it by shipping, and we keep learning it the same way — in our own products, where the support inbox is ours too.
