A real terminal on your iPhone — for every machine you own. SSH boxes, servers, your home lab, and the AI agents you leave running. One command to install, one QR to pair. No VPN, no port forwarding, and encrypted so not even the relay can read a byte.
Two short videos — the desktop app that shares a machine, and the iPhone app that connects to it.
No port forwarding. No VPN. No firewall rules. Just install, scan, and connect.
One command. Auto-detects platform and installs everything.
Open Termcast from your Applications folder.
Download Termcast on your iPhone, then scan the QR code to pair.
Download on the App Store ↗Full terminal on your iPhone. E2E encrypted. Auto-reconnects. Remembers your pairing.
Not a toy. A professional terminal client with the features developers actually need.
X25519 key exchange with ChaCha20-Poly1305. The relay sees only opaque blobs — never your terminal data.
Swipe between tmux windows. Dedicated shortcut bar for splits, new windows, and detach. Auto-resume sessions.
Esc, Ctrl, Tab, arrow keys — all from a dedicated toolbar. Ctrl+C, Ctrl+Z, and tmux prefix shortcuts on tap.
Switch apps, lock your phone, walk to another room. Termcast reconnects automatically when you come back.
Read logs comfortably on any screen size. Pinch to zoom in and out of your terminal content smoothly.
Choose your font, size, cursor style. Per-connection settings so each server feels right.
Think of it as a private mesh for your terminals — set up by scanning one QR code. Pair a few computers with your iPhone and Termcast quietly links them together. From any one of them, open any other's terminal right in your browser — no VPN, no port forwarding, and your phone doesn't even need to be nearby.
Pair your computers the same way you already do. That one scan is the whole setup — your phone links them together, then bows out.
From any linked computer, open any other one's terminal right in your browser. No VPN, no firewall rules, no port forwarding.
Once introduced, your machines talk directly over the same end-to-end encrypted relay — even while your phone is asleep or gone.
Agent-only remotes control a single AI. VPNs still need an SSH client and network setup. Termcast gives you a real terminal on any machine you own — and links them into a mesh — from one QR scan.

Comparison reflects typical out-of-the-box setups; other tools are capable and evolving. Termcast's edge is being a full terminal for any machine, meshed together, with nothing to configure.
Termcast isn't for writing a whole app on a phone. It's for the five minutes when a machine needs you and your laptop isn't there. Here's where it shines — and why it fits.
You set Claude Code or Codex loose on a big refactor and stepped out — now it's stuck on a yes/no question and the whole run is idling until you answer.
Perfect fit Because Termcast is a real terminal, you see the agent's actual screen — approve, redirect, or Ctrl-C right from your phone. It works with any agent, not just one vendor's.
A service falls over at dinner. Prod is throwing 500s, the pager is buzzing, and your laptop is at home.
Perfect fit Reach any box — even a jump host — with one QR and no VPN. Restart the service, tail the logs, and confirm recovery before your food gets cold.
A model is training, a build is churning, a migration is running for hours — and you need to know the moment it finishes or breaks.
Perfect fit Kick it off, leave, and watch from anywhere. Pinch-to-zoom logs, auto-reconnect after your tunnel drops, and step in the instant it asks for input.
Your NAS, your Pi, and the home server all need the occasional poke — but you refuse to punch holes in your router to the open internet.
Perfect fit The server mesh links every box behind your router. No port forwarding, nothing exposed — hop between them from the couch or the office.
A laptop, a cloud VPS, a beefy workstation at home — and you're never sitting at the right one when you need it.
Perfect fit Introduce them once with your phone, then jump from any machine into any other's terminal in the browser. After setup, your phone can stay in your pocket.
Your terminal data is encrypted before it leaves your device. The relay routes messages but can never decrypt them. Not even we can see what you type.
6 automated security checks run on every build before distribution.
All results are public and verifiable.
The app is free for direct connections. Upgrade for encrypted relay access — start with 7 days free.
Ever wish you could fix a website bug or start a new project while waiting for coffee? Now you can. Stop hauling your laptop everywhere and start coding on the go.
Access your computer and files from your phone or tablet. It's like having your office desk in your jeans pocket.
Get instant coding help from Claude and Gemini whenever inspiration strikes. It's like having a genius partner with you 24/7.
Your servers are always within reach. If something goes wrong, you can fix it in seconds, from anywhere in the world.
Whether you're "vibe coding" a new idea or running serious commands, do it all with a few taps.
You don't need to be glued to a desk to be productive. Take your terminal to go and turn every "waiting" moment into a "doing" moment.
