XTermium with four panes in one window: htop on web-01 over SSH, a Grafana dashboard in a web tab, core-switch over telnet, and desktop-01 over VNC with a runbook open; five tabs above them

What it is, in six lines.

  1. You have a lot of machines.

    Servers, switches, Windows boxes, a BMC or two.

  2. Each one wants its own program.

    SSH here, RDP there, a VNC viewer, a browser for the dashboard.

  3. XTermium puts them all in one window.

    Tabs and split panes for every kind. Type once into many terminals.

  4. Your logins stay locked.

    Encrypted on disk, with the key in your OS keychain.

  5. An agent can use it too.

    AI agents open sessions and read the output. They never see a password.

  6. And it is free.

    Apache-2.0, every connection type, every OS. Only sync and Terminal Co-op are paid.

Ten kinds of connection. One window.

How agents work with XTermium

Encrypted on your disk, free for good.

One key in your OS keychain seals everything. A recovery passphrase brings it to a new machine.

  • Sealed with XChaCha20-Poly1305.
  • Apache-2.0: use it, change it, share it; keep the credit.
  • A Rust backend and a GPU-drawn terminal, native on every OS.

Not signed by Apple yet, so macOS blocks the first open of a .dmg from your browser: open System Settings › Privacy & Security, find “xtermium” was blocked to protect your Mac, and click Open Anyway. The command above isn’t blocked. Signing takes a yearly Apple Developer membership; sponsoring on GitHub helps pay for it.
