Meta is entering the AI coding-agent race with Muse Code, a new terminal-based tool now available in beta for macOS and Linux.

Powered by the new Muse Spark 1.2 model, it is designed to handle complex software engineering work across large repositories.

For Mac users, Muse Code installation is a one-line command:

curl -fsS dev.meta.ai/install.sh | bash

Unlike ChatGPT Codex and Claude Code, there’s currently no dedicated app for Muse Code.
