Frequently Asked Questions
? Is HyperKitty hard to install?
HyperKitty offers Docker deployment for simplified setup, though integrating with an existing Mailman3 instance requires configuring REST API access. While some technical knowledge helps, official documentation provides step-by-step guides for both Docker and Django-based installs, making it manageable for most self-hosters.
? Is HyperKitty a good alternative to proprietary mailing list archivers like Google Groups?
Yes—HyperKitty is a privacy-focused alternative that lets you self-host archives and control your data, unlike proprietary options. It integrates deeply with Mailman3, making it ideal for communities that value data ownership and want to avoid third-party platforms.
? Is HyperKitty completely free?
Yes! HyperKitty is open-source software licensed under the GNU General Public License (GPLv3), so it’s completely free to download, install, modify, and self-host without any subscription fees or hidden costs.
