CS DevSync
Sign in

Private beta

Your machines, from anywhere. Even from your phone.

CS DevSync gives you real terminals, files and a live browser on the computers you already own — from a phone on the other side of the world. Your work keeps running on your hardware; you just get a window into it.

Accounts are invitation-only while the beta runs.

Real terminals, not a toy

A genuine shell on the machine — PowerShell or zsh, full colour, scrollback, the tools you already have. Reconnects where you left off when your phone drops the network.

Files both ways

Browse, read and edit text in place, download what you need, and drop a screenshot straight into a terminal — it lands on the machine and its path is typed for you.

See the machine's browser

Drive a real browser window on your desktop from your phone, when a login or a preview only exists over there.

Wake it, keep it awake

Wake a sleeping desktop over the network, or ask a laptop to stay up while you are away from it.

One tap for the usual things

Your projects are discovered automatically: pull, build, run the dev server, or start Claude Code in the right directory — from a phone, in one tap.

Installs like an app

Add it to your home screen and it behaves like a native app, including notifications on the lock screen when a long job stops and wants you.

Your sessions never touch our servers

Terminals, files and the browser view travel directly between your browser and your machine over your own private Tailscale network, encrypted end to end. We coordinate who owns which machine and keep the app updated — we never see, proxy or store what you type, read or run. The agent that runs on your machines is open to inspect, cryptographically signed, and updates itself only after verifying that signature.

  • Every machine is bound to one account; nothing is shared across tenants.
  • Export or delete everything we hold, yourself, at any time.

What you need to start

  1. 1

    A Tailscale account

    Free for personal use. It creates the private network your devices meet on — you own it, not us.

  2. 2

    One command per machine

    The setup guide gives you a single line to paste. It installs the agent, starts it at boot and pairs it with your account.

  3. 3

    Install the app

    Add CS DevSync to your phone's home screen and your machines are one tap away.
