Cairn v0.5.2

Download an installer for your platform from the assets below.

macOS: not yet notarized — on first launch, right-click the app and
choose Open to get past Gatekeeper.

If you still have a problem opening it, use the "Open Anyway" setting:

1. Try to open the app and dismiss the warning dialog.
2. Open the Apple menu and select System Settings.
3. Click Privacy & Security in the left sidebar.
4. Scroll to the Security section — you'll see a message that the app was blocked.
5. Click Open Anyway, enter your Mac's login password, and click OK.

Linux: use the .AppImage (portable), or the .deb / .rpm for your distro.

No Docker needed — Cairn installs the engines it manages (Ollama and, via
uv, Open WebUI) on first run. You just need an internet connection for that
initial setup.
