devpi-server: backend for hosting private package indexes and PyPI on-demand mirrors

PyPI on-demand package mirror

You can point uv, pip or another Python package installer to the root/pypi/+simple/ index, serving as a transparent on-demand mirror for PyPI-hosted packages.

User specific indexes

Each user (which can represent a person, project or team) can have multiple indexes, and can upload packages and documents to these indexes via standard twine or setup.py invocations. Users and indexes can be manipulated through devpi-client and a RESTful HTTP API.

Index inheritance

Each index can be configured to merge in other indexes so that it serves both its uploads and all releases from other index(es). For example, an index using root/pypi as a parent is a good place to test out a release candidate before you push it to PyPI.

Sensible defaults for a low friction deployment

Get started easily and deploy a devpi-server instance with pre-configured templates for nginx and process managers.

Separate tool for Packaging/Testing activities

The complementary devpi-client tool helps to manage users, indexes, logins and typical package upload and installation workflows.

See https://doc.devpi.net on how to get started and further documentation.
