Work from anywhere

Stand up. Walk away. Keep working.

Your sessions run in parallel on your Mac and your phone. Pick up mid-task from wherever you are. The terminal you left open, the screen you were sharing, the files you were browsing. Nothing is lost. Nothing to restart.

Files

File browser

Browse, open, and transfer files between your Mac and your phone. Your entire filesystem, right in your pocket.

All sessions persist. Switch devices whenever you want.

How It Works

Three steps to seamless access

No complex networking. No VPN configuration. Get connected in under two minutes.

01

Install the agent

A lightweight menu bar app runs on your Mac. No ports opened, no firewall rules. It connects outbound to our relay and that's it.

02

Pair your device

Open the iOS companion app and pair securely. Both devices verify a shared code on-screen so no one can intercept the connection.

03

Connect instantly

Open a terminal, share your screen, or browse files. Everything is encrypted end-to-end. If you disconnect, your sessions persist and are waiting when you return.

Security First

Encrypted by design, not by promise

We didn't bolt security on as an afterthought. The architecture makes it impossible for anyone, including us, to see what you're working on. Your keys never leave your devices. Your sessions are yours alone.

Only your devices hold the keys

AES-256-GCM encryption

Every byte between your devices is encrypted with military-grade AES-256-GCM. Keys are derived per-session using ECDH and never leave your hardware.

Zero-knowledge relay

Our servers route encrypted packets but cannot decrypt, read, or store your terminal content. We architecturally cannot access your data.

Verified pairing

Device pairing uses Short Authentication String verification. You visually confirm a code on both screens, preventing any man-in-the-middle attack.

No open ports

Both your Mac and iOS device connect outbound only. No firewall rules, no port forwarding, no attack surface exposed to the internet.
