Offsite Docs

Host your agents on macOS and Linux. Drive them live from your Mac, iPhone and Watch. The real CLIs, your subscription, no wrapper.

Start here

The big pictureWhat runs where, why the CLI is the harness, and how the loop from prompt to test closes on your phone.

Hosts, sessions and clientsThe three pieces the rest of the docs build on.

Install & set upDownload the Mac app, set up This Mac, pair your iPhone by QR code.

Your first sessionFrom a paired host to a working agent, and what happens when you walk away.

What macOS will ask youEvery system prompt you may see during setup, in order, with the reason behind it.

PrerequisitesWhat each machine needs before you install — and what Offsite sets up for you.

HostsThis Mac, a second Mac, Linux — plus surviving reboots and staying awake.

Workspaces & sessionsWhat a session is, why it survives, permission modes, Icebox and handoffs.

The boardCards, tabs, focus mode, keyboard control, themes and file uploads.

Cards & toolsGit, Files, Browser, the Agent Browser, the iOS Simulator, deploy to your phone, Workspace Actions.

Testing what you buildTunnelled dev servers, a browser your agent can drive, a mirrored Simulator, and real builds on your phone.

Phone & WatchThe iOS app, the command bar, notifications, dictation and the Watch.

ConnectivityLAN, Tailscale and the relay — how devices reach your host, and pairing.

Under the hoodThe architecture, what leaves your machine, and what lands on disk.

No account

Offsite has no sign-up and no server-side user. Your Mac is the host; your phone pairs with it by scanning a QR code.

The real CLIs

Sessions run the actual claude, codex and grok binaries in tmux on your machine — with your existing subscription and your keys.

No telemetry

No analytics SDK and no crash reporter. Feedback reaches us only when you send it from the app.

Your wire

Direct on the LAN, over Tailscale, or through the end-to-end-blind relay — whichever is fastest and reachable, switched live.
