Upcoming changes to the Bitnami catalog (effective August 28th, 2025)

Q: Are Bitnami’s free images going away?
A: Not entirely. Bitnami will continue to offer a limited subset of free, latest-version images intended for development use. These images will be more hardened and secure, but older versions and many applications will be removed from the free tier and moved to the Bitnami Legacy repository. You can browse the images available for free at https://hub.docker.com/u/bitnamisecure before August 28th, and after that date, the main Bitnami registry will have the same content.
