We build Terminal-first Agentic Development Environment for

Anthropic's agentic coding CLI. Termio ships it a skill, so it can list, spawn, and answer the sessions running beside it — the panel here is that skill running.

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.

What's inside

Built for agentic coding

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

A fleet you can read

Every session reports a live status — working, finished, or blocked on you — and the same three states aggregate into the menu-bar tray.

Command palette

⇧⌘P runs any action, and Open Quickly jumps to any session, project, or file. Themes preview live as you browse them — Enter keeps, Esc puts it back.

Files beside the terminal

Browse the project, open files in a syntax-highlighted editor, read the git diff, search contents — a side panel that never pulls you out of the terminal.

Markdown you can actually read

Open a README or a plan and Termio renders it — GFM tables, task lists, math, Mermaid diagrams — in your terminal theme, beside the agent writing it.

Your other machines

Termio runs sessions on the hosts in your own ~/.ssh/config, each wearing its machine's mark. System OpenSSH does the connecting — no embedded client, no relay.

A worktree per agent

Worktrees are read straight from git and nested under the project, so two agents can work the same repo without ever touching each other's files.

Also in the box: your Claude and Codex plan limits read from your own credentials, hundreds of terminal themes with light, dark, and glass window looks, 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.
