Parallel Dev Environments for Agentic Coding

mAIestro Code lives in your menu bar and tracks every Claude Code, Codex, Antigravity and GitHub Copilot session you run in parallel.

Free and open source under the MIT license. No mAIestro account, no servers of its own, no telemetry.

macOS on Apple silicon and Intel. Windows 10 and 11 on x64, in preview.

What it does

Live status

Each session says whether its agent is working, waiting for you or idle, so you switch to the one that needs an answer instead of checking every tab.
Plan limits at a glance

A strip shows how much of your Claude, Codex and Copilot plan limits you've used, colored by whether you're on pace to run out before they reset.
Use your favorite IDE or terminal host

Each repo picks where its sessions open: VS Code on macOS and Windows, Terminal.app or cmux on macOS, or Windows Terminal on Windows.
A color per session

Every session gets its own color, so you can pick out its window when a dozen of them are open.
Four agent CLIs

Each repo picks its agent: Anthropic Claude Code, OpenAI Codex CLI, Google Antigravity CLI or GitHub Copilot CLI. Sessions run under your own login.
From idea to issue to pull request

Type a rough idea and the agent drafts the issue. When the work is done, it drafts the pull request, and you watch its checks and merge it from the same list.

mAIestro Code is built in the open. Report a bug, ask for a feature or tell us which agent to support next.
