Evidence

Each bar is one request to the project's own site

This one is installed and run on your own machine, so what we re-check is the project’s site — whether it is still published and still reachable. We cannot tell you from here that the tool itself runs.

How it looked

We hash the visible text on every check, so a redesign registers and a rotating advert does not. An app that has not changed in a long time is not necessarily abandoned — but it is a fact worth knowing before you depend on it.

What it does

A native macOS terminal built on Ghostty and aimed at running coding agents. It has vertical tabs showing git branch, working directory and ports, notification rings that light up a pane when an agent needs attention, split panes, an in-app browser and a CLI for scripting it. It works with Claude Code, Codex, OpenCode, Gemini CLI, Kiro and Aider.

What people say

No reviews yet.

We would rather show none than invent them.

Embed this status

Put it in your README. It updates itself every time we check, and links to your verification record — evidence a stranger can read, not a page selling them something.
