Tilde

macOS and Linux. Then tilde start to keep it running, and tilde pair to add your phone.

• Text, not video

  The Mac sends what the shell writes, not a picture of it. About a megabyte an hour instead of two gigabytes — and the text stays sharp, selectable and searchable.

• It follows you off the network

  On the same Wi-Fi your phone finds the Mac by itself. Elsewhere it reaches it over the internet, through a relay that carries ciphertext and cannot read a byte of it.

• Losing signal doesn't lose your work

  The terminal keeps running on the Mac while the connection is gone. Your phone comes back and picks up what it missed.

• The windows you already have

  Your tmux sessions are listed as they are, and tapping one joins it without resizing what somebody at the Mac is looking at. A new terminal can open on the phone, or in a window on the Mac's own screen.

• It tells you when it needs you

  A long build that finished, or a tool asking for permission, arrives as a notification — sealed on the Mac, so the service that delivers it never learns what it says.

• Keep the Mac awake

  Hold the machine awake from your phone while a job runs, with the lid open or closed, and let it sleep again when the job is done.
