About
Remote access, reimagined
Seasalt is a remote access app for developers who need to reach their Mac from their iPhone. It gives you a full terminal, remote desktop, and file browser, all protected by end-to-end encryption with AES-256-GCM.
Unlike traditional SSH or VPN setups, Seasalt requires zero configuration. There's no port forwarding, no static IP, and no firewall rules to manage. Both your Mac and iPhone connect outbound to an encrypted relay, and keys are exchanged directly between your devices during pairing. The relay never sees your data.
Seasalt is built for developers who run long-running processes, monitor CI builds, manage servers, or just need to grab a file while away from their desk. Your terminal sessions persist, your scroll position is saved, and you can pick up right where you left off. Available for macOS 15+ and iOS 18+. Start with a 14-day free trial, no credit card required.
How It Works
Three steps to seamless access
No complex networking. No VPN configuration. Get connected in under two minutes.
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.
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.
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.
Use cases
Built for developers who ship
Run Claude Code from your iPhone
Complete setup guide. Install Claude Code CLI on your Mac, pair with Seasalt, and run AI coding sessions from your phone in under 5 minutes.
Read the guide →Monitor long-running builds
Kicked off a CI pipeline or a Cursor AI coding session? Check progress from your phone without context-switching. Your terminal output streams in real time.
Grab files on the go
Browse your Mac's filesystem, open documents, or transfer files to your iPhone. No AirDrop proximity required, no iCloud sync delays.
Manage servers and processes
Restart a service, tail logs, or SSH into staging, all from a proper terminal on your phone. Multiple concurrent sessions supported.
Check in from anywhere
Left something running at home? Seasalt connects through NATs and firewalls automatically. No VPN, no same-network requirement, no open ports.
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.
