What it solves

Termio is a terminal-first agentic development environment (ADE) designed for a workflow where AI agents perform the majority of the coding. It solves the problem of managing multiple parallel AI agents (like Claude Code or Codex) running in separate terminal sessions, allowing developers to monitor their status, review their changes, and unblock them when they get stuck, without needing a full IDE.

How it works

Termio provides a high-performance native Mac terminal (built with Swift, AppKit, and libghostty) that organizes sessions into projects and git worktrees. It automatically detects the status of CLI agents (working, idle, or needing user input) and signals this via a menu-bar tray and session dots. It includes a read-only git pane for reviewing changes and a file tree for quick edits.

Additionally, it provides a termio CLI that allows agents to script their own environment—such as spawning sibling agents or reading their output—and a companion iOS app that mirrors the live TUI of Mac sessions for remote monitoring and interaction.

Who it’s for

Software engineers and developers who use CLI-based AI agents for coding and want a centralized, native environment to manage and supervise them.

Highlights

• Native Performance: Built with Swift and Metal, avoiding Electron or xterm.js for a real terminal experience.
• Agent Status Tracking: Built-in hooks for popular CLI agents to signal when they need human intervention.
• Agentic Scripting: A CLI that allows agents to spawn and manage other agent sessions.
• Mobile Mirroring: A companion iPhone app that mirrors the full TUI of active sessions.
• Git Integration: Integrated read-only git pane and support for git worktrees to handle parallel tasks.
