4x

CLI that splits AI coding work into isolated Design, Code, Review, and Test agent roles.

Desktopfreeglobal

4x is an open-source command-line tool that orchestrates AI coding agents into separate Design, Code, Review, and Test roles, so the same model doesn't write and approve its own code. It enforces guardrails like scope locks and evidence-based test gates directly in the CLI rather than by prompting, and supports batching many features for overnight processing. It targets development teams building features that need to survive contact with production.
