What is bandersnatch?
Bandersnatch is a PyPI mirror client that creates and maintains a local copy of the Python Package Index. It implements PEP standards 381, 503, and 691 to sync static package metadata and files, enabling organizations to host their own Python package repositories. This solves problems like high latency, bandwidth constraints, and dependency on PyPI's availability for package installations.
System administrators, DevOps engineers, and organizations that need to host a local PyPI mirror for internal use, CI/CD pipelines, or air-gapped environments. It's also for Python packaging maintainers who require reliable, standards-compliant mirroring tools.
Developers choose Bandersnatch because it's the official PyPA-supported mirroring tool with full PEP compliance, ensuring compatibility with pip and other Python package managers. Its plugin system and Docker support make it highly customizable and easy to deploy in various infrastructure setups.
