We build Terminal-first Agentic Development Environment for

Anthropic's agentic coding CLI. Session status flows into the sidebar as it works.

Agents driving agents

The termio sessions CLI turns the fleet into an API: any agent — or your own scripts — can start siblings, answer their prompts, and supervise the whole project without touching a GUI.

Pinned JSON shapes, explicit waits, honest exit codes — read the API docs.

What's inside

Built for watching agents work

Several agents going at once, most of them fine without you, one of them stuck — Termio keeps the whole fleet in view.

Knows when an agent needs you

Session dots show working, idle, or needs-you, aggregated into a menu-bar tray — calm while agents work, ringing the moment one is blocked on you.

Command palette

Jump to any session, project, or action from one search box — themes too, previewed live as you browse, Enter to keep or Esc to revert.

Usage at a glance

Your Claude and Codex plan limits in Settings, read locally from your own credentials — no proxy, no account.

Native appearance

Light, dark, and a glass look that follows the system, with hundreds of built-in terminal themes or your own. A real Mac app, down to the chrome.

Also in the box: git worktrees nested under each project, a read-only git pane with unified diffs, a click-to-edit file editor, and Ghostty-style split panes.

Your sessions, from anywhere

Start an agent on your Mac, then keep the same live terminal in reach from your iPhone — check progress, answer prompts, approve a blocked run.

Same session
The phone attaches to the Mac's terminal — output, prompts, and status stay in sync.
Works away
Direct over LAN at home, an outbound tunnel when away. No port forwarding.
Paired, not hosted
Pair every Mac you work on with a QR code and switch between them. Token-gated, no Termio cloud in the middle.
