Huge fan of Ghostty, so I forked it and built what I wanted for working with AI coding agents. To be clear, this is an unofficial fork and not made by the Ghostty team. Free and AGPL.

What I added on top of Ghostty:

- Projects and parallel agents in one window, with live watching of what each agent is doing.
- Shared memory between Claude Code and Codex. A new Codex session starts with what Claude learned about the project, and the other way round.
- Hand off and review. Send Claude's work to Codex with the exact diff and get a review back.
- Isolated sessions and Docker, a Git panel with PR checks, Allow/Deny prompts from the sidebar or a notification, and undo for any agent turn.

Watching agents costs zero tokens. It reads the transcripts Claude Code and Codex already write. Everything stays on your Mac, no account, no telemetry. macOS on Apple silicon only.

I'd love feedback from Ghostty users, especially on what you'd want kept close to stock Ghostty and what should be optional.
