Develop on the go exactly as you do at your desk. Your agents work around the clock. CLI only, no wrapper.
The real claude, codex and grok. Your subscription, your keys.
Do the laundry. Ship the feature.
A MacBook on your desk, a Mac mini in the closet, a Linux VPS in the cloud. Offsite keeps them all warm and races every route on connect: direct LAN, your Tailscale, or the optional end-to-end blind relay. The pill never lies: real path, real latency, live.
Relay is per host and off whenever you say so. Direct stays direct.
Real screenshot. LAN at 7 ms. The relay only when you need it.
Everything runs on your machines, mirrored to your devices. Nobody else’s server in between.
| Your whole environment on every device | Agents, terminal, git diffs, files, browser and simulator, mirrored live between Mac, iPhone and Watch. |
|---|---|
| The real CLIs, not a wrapper | The 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 phone | Web apps over an SSH tunnel, in a real browser card with tabs and dev tools. iOS builds straight to the phone in your hand, no TestFlight. The simulator mirrored from your Mac. |
| Agents on your wrist | Watch 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 included | Host-owned tmux plus claude --resume and codex resume, wired in per tool, automatically. |
| Works with your laptop fully off | The 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 board | Claude 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. |
| Point at the bug instead of describing it | Mark an area in the browser card, circle what is wrong, number it, write a line per number. The agent gets the marked screenshot, your notes, the URL and the element's selector, instead of "the blue one, below the header". |
| A browser your agent drives itself | A real Chromium on your host, in a card: the agent opens the page it just built, reads it, clicks and screenshots, with no extension or automation stack to install. You watch the cursor move and take over whenever you want. Responsive by default, plus iPhone, iPad and desktop sizes. |
| Pass context between agents | Ask one session what another concluded, or start a fresh session that inherits the context of a long one. A session can read another, never type into it. |
| Runs on your existing subscriptions | No metering, no token resale, zero cost per agent hour. |
| Direct by default, relay only when needed | Every 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 handoff | Wi-Fi to hotspot to hotel network: dead paths are detected in seconds and the connection migrates. Sessions never notice. |
| Realtime voice input | Speak 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 servers | No account, no telemetry, no crash reporter. A push notification carries the session and workspace name so you know who wants you, never terminal content, code or prompts. Verify with tcpdump. |
| Native apps, no subscription | A real Mac app, a real iPhone app, a real Watch app. No Electron. Pay-once model after the beta. |
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 spells out the rest.
It is arithmetic. 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.
No. Offsite runs the official CLIs with the Claude, ChatGPT or Grok plan you already have. We never meter or resell tokens.
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.
Yes. The Agent Browser is a real Chromium on your host that the agent drives with built-in tools. No extension, no Playwright setup, nothing to keep alive. It opens your dev server, reads the page as text, clicks, fills forms and takes screenshots. It is a card, so you watch it work and take over whenever you want, on any device.
It stays on your machines. SSH end to end; the optional relay cannot decrypt it. Verify with tcpdump.
For your sessions, 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. The one readable exception is a push notification: a lock screen has to display it, so it carries the event plus the session and workspace name, never terminal content, and it can be turned off per device. The security page lists every byte that leaves your machines.
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.
Your sessions are plain tmux plus the official CLIs. Nothing is locked in.
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.
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.
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.
Install on your Mac, pair your iPhone, walk out the door. That’s the whole setup.
