HyperKitty, the next-generation mailing-list archiver

HyperKitty is a Django-based application providing a web interface to access GNU Mailman v3 archives, and interact with the lists.

The project page is https://gitlab.com/mailman/hyperkitty.

There is a demo server available, but it’s also a development server, so it may be broken at the time you access it. It’s usually OK though.

The authors are listed in the AUTHORS.txt file.


Why HyperKitty?

Mailman is in need for replacement of its default Pipermail archiver. It is over 10 years old, users’ expectations have changed and their requirements are more sophisticated than the current archiver can deliver on. Mailman3 is the currently under active development and it offers a pluggable architecture where multiple archivers can be plugged to the core without too much pain.

Some of the drawbacks of Pipermail :

  • It does not support stable URLs.

  • It has scalability issues (it was not suitable for organizations working with hundred of thousand of messages per day, e.g, Launchpad)

  • The web interface is dated and does not output standards-compliant HTML nor does it take advantage of new technologies such as AJAX.

The HyperKitty archiver addresses most of the drawbacks of Pipermail.
