What Astral is

Astral makes open-source developer tools for Python, including Ruff, a linter, and uv, a package and project manager. Both are written in Rust, and the company’s stated aim is to make the Python ecosystem more productive. uv brings together project management, a universal lockfile, script execution, Python version management, tool installation, workspaces and a pip-compatible interface. That interface is described as offering a 10–100x speedup over pip. uv supports macOS, Linux and Windows, with documented integrations across tools and services including Docker, Jupyter, GitHub Actions, PyTorch and AWS Lambda. Astral says its tools are permissively licensed and free. The company also describes security controls for workflows and releases, including read-only default workflow permissions and release attestations. Documentation directs users to the Discord community for support. The separate pyx registry is no longer accepting new signups. Astral has announced an agreement to join OpenAI as part of the Codex team.
