Termio runs on Apple Silicon Macs. Installation is a normal drag-to-Applications — there's no account to create and no license key to enter.
Before you begin
Termio is an Apple Silicon (M-series) Mac app running macOS 14 or later. It hosts the agent CLIs you already have installed — it doesn't bundle them.
Download and install
- Download the latest build from downloads.termio.sh. The link always serves the newest notarized release.
- Open the
.dmgand drag Termio into your Applications folder. - Launch it from Applications. Because the app is notarized by Apple, it opens without a Gatekeeper warning.
Staying up to date
Termio updates itself through Sparkle. It periodically checks the download server for a newer version and offers to install it in place. The check carries no account or device identifier — the server sees only an IP address and the version being asked about.
You can trigger a check any time from Termio ▸ Check for Updates.
Bring your own agents
Termio doesn't bundle the coding agents — it hosts the ones you already have on
your Mac. Install whichever CLIs you use (for example claude, codex, or
gemini) and make sure they're on your PATH. Termio launches each one in a
login shell, so anything your shell profile sets up will be available.
Once an agent is installed, it shows up as a launchable option when you start a session.
The termio command (optional)
Termio ships a small command-line tool. Open Settings ▸ General and click
Install Command-Line Tool to symlink termio onto your PATH. From then on
termio in any directory opens it as a project, and termio sessions … lets your
agents coordinate with each other. It's entirely optional — see
Session control & the CLI.
