Run Reef on your own Mac

Your hardware. Your data. Your agents.

Reef runs entirely on your hardware. Your data and your agents live on your Mac; reef.co is just the front door — reach your box from anywhere, and pull the plug on the cloud whenever you want.

Requirements: Apple Silicon Mac (M-series), macOS 14+, an admin password (one-time).

1. Download

Download the Apple Silicon package: reef-selfhost-<version>-arm64.pkg.

Download for Apple Silicon

2. Install

Double-click the .pkg and follow the installer (admin password once). Or Terminal:

sh
sudo installer -pkg ~/Downloads/reef-selfhost-<version>-arm64.pkg -target /

3. Set it up

Open http://localhost/ on that Mac. Sign in with Google (your email becomes the box's allowlist), paste your Anthropic API key, create your first agent.

4. Reach it from anywhere

reef.co/boxes → Connect. Open your box from any device; traffic runs over an encrypted uplink straight to your Mac — Lobster never stores your data.

Updates

Your box updates itself (health-gated, auto-rollback); you'll get a prompt when a new version is ready.

Uninstall

The bundled uninstaller removes Reef; your data is preserved unless you pass --purge-data.
