Start tasks from the subway, watch progress on your lock screen, approve risky commands with one tap — and when you need hands on the machine, Remote Desktop puts its screen on your phone. Runs on your own computer, end-to-end encrypted. Mac, Linux and Windows.
Tool calls and permission requests land on your phone for a one-tap allow or deny — away from the desk, nothing gets past you.

Two coding agents, one instrument. Switch a window’s engine mid-conversation and the context comes along; pick the model and reasoning effort per window.
native drive: streaming output, tool cards, resumable sessions
deep app-server integration, approvals through the same gate

when one account runs dry, the next takes over automatically
Everything between phone and computer is end-to-end encrypted; the keys live on your two devices only. Whoever runs the relay just moves ciphertext it can’t read — not one word of your session. Away from home it connects automatically: no public IP, no port forwarding.
Phone and computer on one Wi-Fi. Scan the QR and you are paired — direct, zero config, lowest latency.
Recommended — more private, the rendezvous is yours end to end. Works with or without a domain; recipe below in Cast off.
Zero setup — run for you and free too, so newcomers just connect. Want more privacy? Self-host one (see Cast off).
direct at home, relay when you leave — it switches under you, no toggles.

The computer’s screen, live on your phone: trackpad gestures as the mouse, a soft keyboard with a shortcut bar, system audio and clipboard along for the ride. Hardware codecs, direct P2P first, the same encrypted link as chat. Controls macOS and Windows; a Pro feature.
One window per project — several projects, several assistants, all working at once.
Scan to install on your phone
Point your phone camera at the code above
iOS · App Store Android · APKOr just open sextant.top on your phone
The iOS app is live on the App Store — tap above to get it. Android installs from the APK directly for now (you may need to allow installing apps from unknown sources).

Above were the highlights. This is the app’s full feature tour — every item is built and shipping, not a roadmap.
It lives on your machine — your files, your env, your logins. The phone is just the remote.
Direct on the same Wi-Fi; an encrypted relay punches through when you leave. No router config.
Claude Code and OpenAI Codex both drive; one engine per window, quotas counted separately.
Drafts a checklist, works and tests item by item — only green ticks count. Stuck? It changes tactics.
One big task split across parallel agents, merged at the end. Strongest — and hungriest.
One window per project; several tasks run at once without stepping on each other.
Commands wait on your phone; edit them before approving, answer from the lock screen.
Read, edit, Bash, network, subtasks, skills, MCP — each class set to allow / ask / deny. Side project automatic, company repo asks.
Even under “allow all”, rm still pops one more confirmation.
Paste one line on the computer, scan with the phone — that’s genuinely it.
curl -fsSL relay.sextant.top/install | sudo sh
Installs as a persistent service — running it again upgrades; the pairing QR and an 8-digit code print in the terminal, scan or type it and you’re connected. No Claude Code or Codex yet? One tap in the app installs it, and on Windows even Node.js and Git are set up for you.
To connect away from home you need a relay as the meeting point. The official one is free, but self-hosting is better — content is already end-to-end encrypted and the relay only moves ciphertext, so hosting it just keeps the meeting point in your hands. Three steps, no domain required:
① Get the relay — one command, installs and runs
npm i -g sextant-relay && sextant-relay
Run it on a server with a public IP; npm fetches the right binary for the platform and starts it, listening on 7290 by default — open that port in the firewall. No Node? go build ./relay works too.
② Point the computer at your relay (pick one)
sxt --relay-url ws://YOUR_VPS_IP:7290
Just use ws:// + the server IP. A plain port is fine — the content is already end-to-end encrypted; the relay only ever sees ciphertext.
Two lines of Caddy, auto-certificate (use your domain):
your-relay.com {
reverse_proxy localhost:7290
}sxt --relay-url wss://your-relay.com
Want it to auto-start on boot? Attach a systemd service to the relay (example in the repo).
Content is end-to-end encrypted either way — even the official relay sees only ciphertext. Self-hosting just puts the meeting point in your hands too.
The iOS app is already on the App Store. One email when Sixant reaches Google Play. No list, no noise — just the launch.
