Finds your Macs
Macs on your network show up by themselves, each with the right icon. Tap one to add it.

Nothing to install on your Mac
Screen Door uses the Screen Sharing built into macOS. Turn it on, then sign in with the same username and password you use on the Mac.
At home or away
Give a Mac its Tailscale address too. Screen Door uses your local network when it can, and Tailscale or another VPN when you're out.
Made for touch
Look around and zoom without touching the Mac, or switch to Mouse mode to click, scroll and drag.
Like being at your desk on iPad
Use a trackpad, mouse or hardware keyboard. Each Mac opens in its own window, so you can keep two side by side.

Private and open source
No account, no analytics, no tracking. The code is on GitHub.
New
Made for iPhone Duo
Open it, and your Macs sit beside the one you're using. Stand it up like a laptop, and it becomes a little MacBook.
Open for two
Your Macs on one side of the fold, the one you're using on the other. One button takes it full screen, and the same button brings the list back.
A MacBook in your pocket
Fold it partway and stand it on a table. The Mac's screen moves to the top half. Below the fold, a full Mac keyboard with a trackpad under it. Tap ⌘, then C, to copy.
Picks up where you left off
Close it and you stay on your Mac, still connected. Open it again and the list is back beside it.
Shortcuts in the toolbar
Mission Control, Spotlight, Switch Apps, screenshots and Lock Screen stand in the bar beside the screen.
Every key a Mac needs
Command, Option, Control, Shift, esc, tab and the arrow keys sit right above the keyboard. Tap a modifier, then the key, for shortcuts like ⌘C.

On Apple Vision Pro, as big as you like
Look at something and tap to click it. The window takes the shape of your Mac's screen, and you can put it anywhere.
Set up in a minute
- On your Mac, open System Settings > General > Sharing and turn on Screen Sharing.
- Open Screen Door. Macs on your network appear in the list.
- Tap your Mac and sign in with your Mac username and password.
Your password is stored in the Keychain on your device. Screen Door connects straight to your Mac. There are no Screen Door servers in between.
