Is there a free AI coding app for Mac?

Yes. Wavefunction, Yardlet and Mudroom are free and open source (MIT), and Termy is free with an optional $4.99 Pro upgrade. You still need a model: your own API key, a local model, or an AI plan you already have.

Which Mac app is a coding agent on its own?

Wavefunction is a full coding agent: you connect a model (local, your own key or a ChatGPT sign-in) and it does the work. Most other apps here run agents you already have, like Claude Code and Codex.

Can I run Claude Code and Codex side by side on a Mac?

Yardlet, Starkomand, SKI, ManyAgents and Harness all run several agents at once, most with a git worktree per agent. The multi-agent coding list has more, including tools for teams.

Can I keep a coding agent away from my real files?

Mudroom runs the agent in a Linux micro-VM on a copy of your project, and Wavefunction runs computer use in a local Docker container. The free AI coding tools list covers more free options.

Is there a Windows version?

BAND runs on macOS, Windows and Linux, and VibeiDE on macOS and Windows. On Windows only, nana is a free-beta terminal that runs coding agents side by side.

Best AI coding apps for Mac

These are desktop apps you install on a Mac, not browser tools or plain CLIs. Some are a coding agent on their own; most run the agents you already use, like Claude Code and Codex, in a better window. Every tool here names the Mac or macOS in its DreamBuilds listing, and prices are shown only where they were verified.

10 tools. Ordered by how directly each listing matches this job, judged from its DreamBuilds description. This is an editorial order, not a benchmark or a test result.
