The features

Yes, at the core this is tmux over SSH. Here is what we add.

Your whole environment on every deviceAgents, terminal, git diffs, files, browser and simulator, mirrored live between Mac, iPhone and Watch.
The real CLIs, not a wrapperThe exact claude, codex and grok binaries: same flags, config, MCP servers and skills. New CLI features on day one, on desktop and phone.
Test agent builds from your phoneWeb apps over an SSH tunnel. iOS builds straight to the phone in your hand, no TestFlight. The simulator mirrored from your Mac.
Agents on your wristWatch app plus watch-face complication: see who needs you, read the question, answer with a tap or dictate. Runs through your paired iPhone.
Survives crashes and reboots, conversation includedHost-owned tmux plus claude --resume and codex resume, wired in per tool, automatically.
Works with your laptop fully offThe host runs on any Mac or Linux box you own: under your desk, in a rack, or on a VPS. The apps are thin mirrors, so nothing depends on them.
Every provider on one boardClaude Code, Codex, Grok and your shell, side by side, each in its native CLI. A grid board instead of tabs: see who is running and who is waiting.
Runs on your existing subscriptionsNo metering, no token resale, zero cost per agent hour.
Direct by default, relay only when neededEvery connect races the fastest path: same Mac, LAN, Tailscale, relay. The optional relay is end-to-end blind, SSH ciphertext only, switchable per host.
Seamless connection handoffWi-Fi to hotspot to hotel network: dead paths are detected in seconds and the connection migrates. Sessions never notice.
Realtime voice inputSpeak your prompt on iPhone or Watch; words appear live as you talk, with a clean fallback on bad networks. Uses your OpenAI key.
No content on our serversNo account, no telemetry. Push notifications carry no content, just that a turn finished. Verify with tcpdump.
Native apps, no subscriptionA real Mac app, a real iPhone app, a real Watch app. No Electron. Pay-once model after the beta.
FAQ

The questions Hacker News will ask.

Is this just tmux over SSH?

At the core, yes. On top: full-environment mirroring, per-tool conversation restore after reboots, phone-side testing of agent builds, hook-based notifications, the grid board, native apps. The feature list above is the honest version of this answer.

Is “3x output” real?

It is arithmetic, not magic. Agents idle whenever they wait for you. At a desk you unblock them 8 hours a day. With the whole environment in your pocket you unblock them whenever you glance at your phone. Your agents work more hours. You do not.

Do I need another AI subscription?

No. Offsite runs the official CLIs with the Claude, ChatGPT or Grok plan you already have. We never meter or resell tokens.

Do I need Tailscale or a VPN?

No. Flip on the relay toggle and your host is reachable from anywhere: both ends dial out, so there is no port forwarding, no Remote Login, no VPN. If you have Tailscale anyway, Offsite uses it: every connect races all paths and the fastest direct one wins. Prefer zero third parties? Leave the relay off.

What happens to my code?

It stays on your machines. SSH end to end; the optional relay cannot decrypt it. Verify with tcpdump.

So nothing of yours can read my traffic?

Correct. Direct connections have nothing in between. The optional relay pipes SSH ciphertext it cannot decrypt: your devices pin the host key, so even a compromised relay could disrupt but never read or inject. Push notifications carry no content, just events, and can be turned off. Both are optional and off when you say so.

What does it cost?

Nothing during the beta: macOS, host, iPhone and Watch are free. After launch, Offsite becomes a pay-once license, no subscription, and beta testers get a discount. We will publish exact pricing before the beta ends. No bait and switch: you will never be silently moved onto a paid plan.

What if Offsite the company goes away?

Your sessions are plain tmux plus the official CLIs. Nothing is locked in.

Mac only?

Hosts: macOS and Linux (Ubuntu, Debian, x86 and ARM). Clients: macOS, iOS and watchOS. The Mac app bootstraps a Linux host over SSH, no manual install.

Does it work on Apple Watch?

Yes. Notifications, a watch-face complication with live agent status, the session's live output, tap-to-answer for agent questions, and dictated replies. The watch talks through your paired iPhone.

Does it work when my laptop is closed?

If the laptop is the host: yes, close the lid, sessions keep running and the app keeps the host awake. If the host is another machine: your laptop can be fully off.
