The problem

You’ve found something you want to watch on your phone or laptop.

You want to see it on your TV.

Your options in 2026:

• AirPlay: Can’t use your phone for anything else while AirPlaying. Sometimes TV audio level is tied to phone volume.
• AirPlay screen mirroring: Slow with heavy artifacting. The New York Times crossword is unplayable. Can’t cast a single window.
• Chromecast classic: Barely supported. Some YouTube videos silently refuse to play.
• Chromecast with Google TV: Often needs you to press a button on its remote to start playback.
• Chromecast screen mirroring: Can’t cast the screen with audio.

Abeam

Abeam is an app for your iPhone and Mac that helps you do two things:

1. Put a video on your TV by URL.
2. Mirror your screen to your TV.

Send a video

Use the Share button in your video streaming app to send a video to your screen. Chromecast and AirPlay support does not need to be built into the streaming app.

Currently supported services:

• YouTube
• Dropout

Seeking contributors: Please help implement support for more services. Here’s how you can help:

1. Tap the Share button in your unsupported sharing service and create a Note with the result. Copy that text and file it as a GitHub issue in this repository.

   Self-promotion: Need to move that text to your computer? Try Degap.

2. Know how to code? Send me a pull request with a VideoParser for the service (in //Abaft/VideoParsers).

Screen mirroring

Screen mirroring is based on ScreenCaptureKit. Not all platforms supported by Abeam have ScreenCaptureKit available, so screen mirroring is conditionally compiled out with macros of the following form.

#if canImport(ScreenCaptureKit)

ScreenCaptureKit is only available on the following:

• macOS. All versions of macOS supported by this app support ScreenCaptureKit.
• Physical iOS 27+ devices. Simulators are not supported.

Abaft

Abeam has a companion app called Abaft that runs on a Mac connected to your TV. Abaft shows the videos you send or your mirrored screen full screen.

For sending videos, Abaft works like a web browser. Log in and dismiss cookie banners directly in Abaft from your keyboard and mouse, then put your peripherals away.
