Download APK

  1. Open Polyth on your computer

    The desktop app, or your server in a browser.

  2. Pair the phone

    Scan the QR code, use nearby discovery or type a six-digit code.

  3. Approve it

    From then on the phone reconnects on its own, without opening any port.

Your own server

For a team, run one Polyth server on a machine everyone can reach: a workstation, a home server or a VPS. People sign in from any browser and pair their phones to it.

Docker

The image includes the server, OpenCode, Git, the GitHub CLI and Polyth Link. Add a Caddy proxy for automatic HTTPS.

git clone https://github.com/Polyth/Polyth.git
cd Polyth/deploy/docker
cp .env.example .env
docker compose build
docker compose run --rm polyth setup-claim
docker compose up -d

From source

Needs Node.js 22.16 or newer and at least one agent CLI installed and signed in.

git clone https://github.com/Polyth/Polyth.git
cd Polyth
npm install
npm run build
npm run setup:claim
npm start

Setup prints a one-time claim token. Open http://127.0.0.1:4400, paste it, create the owner account and keep the recovery codes. The README covers HTTPS proxies, upgrades and backups.

Questions.

Which version is this?

The newest build from the stable channel, version 1.2.281. The desktop app can update itself and lets you pick a release channel in its settings.

What does the desktop app include?

A complete Polyth server running on your computer, OpenCode, and Chromium for the built-in browser. Install Claude Code, Codex or any other agent you want to use and sign in to it as usual.

How do I install the Android app?

Download the APK on the phone and open it. Android asks once whether your browser may install apps; allow it, install, then pair the phone with your Polyth server.

Can I use Polyth without the desktop app?

Yes. Polyth is one server and any number of clients. Run the server in Docker or from source, and open it in a browser or the phone app.
