termalTermalin · browser cabinet
The web SSH client with nothing to install.
Sign in at termal.in/account and get a real terminal on your hosts from any browser — plus SFTP, FTP and S3 file browsers, snippets and session recordings, all adapting to a phone. Private servers stay reachable through a keyless Termalin Connector, with no key ever entering the browser. Try the live demo — no account needed.
Free tier · 14-day Pro trial · Windows, macOS & Linux
01 / no install
A real terminal in the tab you already have open.
The browser cabinet is the same client, in the browser — a real terminal on your hosts, not a viewer. It works from a laptop, a phone, a tablet, a borrowed machine, or a locked-down work computer where you can't install software. Open termal.in/account, sign in, connect.
- ▸A real terminal on your hosts, from any device with a browser — the layout adapts down to a phone.
- ▸Files on the go — SFTP, FTP and S3 file browsers for browsing, uploading and downloading.
- ▸Snippets and per-host command history — end-to-end encrypted and searchable from the cabinet, same as the app.
- ▸Session recordings — on paid plans, replay cloud recordings right in the cabinet on a scrubbable timeline.
02 / behind the firewall
Reach private servers — no open port, no key handed out.
For a server behind a firewall, run one line to install a tiny Termalin Connector — no inbound port to open, and no SSH key to hand out. Then connect from the browser, keyless: no key ever enters the browser. The same enrolled servers are also what Termalin's hosted MCP endpoint can reach, so your AI agents can work on them too.

- ▸One line to enroll — install the agent on the server and the tunnel comes up on its own.
- ▸Nothing exposed — no inbound port on the server, no key to distribute or revoke later.
- ▸Keyless from the browser — connect from the cabinet without a password or a key.
03 / honestly
The desktop app is still the full experience.
The cabinet doesn't replace the desktop app — but it's no lite mode either: a grid view of every session, send-to-all broadcast, tunnels, command history and even Telnet run right in the browser. The app for Windows, macOS and Linux adds the dual-pane file manager, the master password with auto-lock, and the built-in MCP server for AI agents. With Pro's end-to-end encrypted sync, the same hosts, snippets and history show up in both. Get the desktop app →
Questions
Is the web SSH client free to try?
The live demo at termal.in/account?demo is free and needs no account. Every new account starts with a 14-day Pro trial — no card required. The Free tier is the whole desktop app, local-only with no host limits; Pro adds the encrypted cloud at $8/mo billed yearly or $10 monthly. See pricing →
Do I need to install anything?
Not on the machine you're browsing from — the cabinet runs entirely in the browser, on a laptop, phone or tablet. For a private server behind a firewall, you run one line on the server itself to install the tiny Termalin Connector; after that you connect from the browser, keyless.
How does it reach a server behind a firewall?
Through the Termalin Connector: run one line to install it on the server — no inbound port to open, and no SSH key to hand out. The server stays reachable from the browser cabinet, keyless.
Is SSH from a browser safe?
No SSH key ever enters the browser — private hosts are reached keyless through the Termalin Connector. Your vault is end-to-end encrypted with a key derived from your master password, so the server stores only encrypted blobs it can't read. More on security →
Does the web cabinet replace the desktop app?
It complements it. The cabinet is close to a full client — a grid view of every session, send-to-all broadcast, tunnels, command history, SFTP/FTP/S3 and even Telnet in the browser. The desktop app adds the dual-pane file manager, the master password with auto-lock, and the MCP server for AI agents. Use the cabinet from a phone, a tablet, or a machine where you can't install software. Download →
