Prefect, the Python-native workflow orchestration server for data pipelines. prefect from PyPI in a Python 3.13 venv on a hardened nonroot Wolfi base; the default command runs the server (API and UI on 4200), and the same image runs workers and flow code.

Version

The latest line lives at the base page; older lines have their own page so you can pin and verify exactly that version. Only the most recent releases are listed — an older chart pins an older image digest.

The chart pins its image by this signed digest, so you never track it yourself. Signatures, SBOM, and provenance attach to the same digest.
