Download Turret.

macOS

For Macs with Apple silicon. Turret arrives as a zip holding Turret.app. Open the zip and drag Turret.app into your Applications folder.

The Mac build is signed and notarised, so macOS opens it after its usual check on an app from the internet.

Computer use on a Mac keeps its permissions only for /Applications/Turret.app, so run it from there.

Windows

For 64-bit Windows on Intel or AMD. Turret arrives as an installer. It installs for your account alone, and needs no administrator rights.

The installer isn't signed yet, so the first time it runs Windows shows a blue panel headed Windows protected your PC. To carry on:

1. Press More info.
2. Check the app is Turret-Setup with the version you downloaded.
3. Press Run anyway.

Linux

For 64-bit Linux on Intel or AMD. Turret arrives as an AppImage, one file that runs on its own.

The AppImage isn't signed. Before the first run, mark it as a program. Allow it to run as a program in the file's properties, or run chmod +x on it. Then open it.

Computer use on Linux needs GNOME on Wayland, or an X11 session.

After the first launch

Turret checks for a new version when it opens and every four hours after that. It downloads the update in the background, and installs it when you press Restart now.

Turret opens on a card for each engine. Press Sign in to Claude Code or Sign in to Codex, or add a Gemini or DeepSeek API key in Settings. Turret installs Claude Code or Codex for you if it isn't there.
