Clear message

Help us test PyPI!

Warehouse is a next-generation Python Package Repository which will replace the existing code base that currently powersPyPI (source code on GitHub,roadmap). We are seeking maintainers of Projects on PyPI to test it and send us bug reports.

Since Warehouse must be a reimplementation of the existing PyPI, please focus on any differences, missing features, or incorrect behavior that is exhibited on that affect your workflows for account management and package maintainership initially. We'll be soliciting feedback on other concerns soon! Feedback on user experience, accessibility, and overall ease of use are welcome. Go to the pre-production deployment at and try it out!

Things to test

Most of these you can test on, using the same login as you use on (legacy PyPI). For testing destructive actions, like removing an owner, deleting a project, or deleting a release, please use



If you find any potential security vulnerabilities, please follow our published security policy. Please don't report security issues in Warehouse via GitHub, IRC, or mailing lists. Instead, please directly email one or more of our maintainers.

IRC livechat hours

Warehouse developers will be in IRC, in #pypa-dev on Freenode, and available to talk about problems you run into, or about how to hack on Warehouse:

  1. Tuesday Feb 27th: 1700 UTC / noon-1pm EST

  2. Thursday March 1st: 1700 UTC / noon-1pm EST

  3. Thursday March 1st: 2300 UTC / 6pm-7pm EST

Feel free to drop in!


We're working hard on nearly every aspect of the Warehouse codebase to get it ready for production deployment and are shipping features nearly every day, so check back and maybe even try using for your maintainer activities full time. Due to the rate of change some errors, downtime, and outright broken features may occur. We have some automated reporting of the scenarios in place, but let us know!

Reminder! Sign up for the PyPI Announcement Mailing List to be kept in the loop as we continue this process!

Contact us

Thank you for testing Warehouse! You're helping us launch sooner and future users of PyPI will appreciate it. :)
