Astral vs revive

Astral makes open-source tools for Python development, including Ruff, a linter, and uv, a package and project manager. Both are written in Rust. uv brings together project management, a universal lockfile, script execution, Python version management, tool installation, workspaces and a pip-compatible interface. Astral describes that interface as providing a 10–100x speedup over pip. uv supports macOS, Linux and Windows. Its documented integrations include Docker, Jupyter, marimo, GitHub Actions, GitLab CI/CD, pre-commit, PyTorch, FastAPI, Bazel, artifact registries, Renovate, Dependabot, AWS Lambda and Coiled. Astral says its tools are permissively licensed and free forever. It describes security controls for workflows and releases, including read-only default workflow permissions, full-length commit-SHA pinning, Trusted Publishing, Sigstore attestations and immutable GitHub releases. Documentation directs users to its Discord community for support. The separate pyx package registry offers optimized installs and other package-management features, but is no longer accepting new signups. Astral has announced an agreement to join OpenAI as part of the Codex team.
