Verdict
A disk-native photo cataloguer and batch editor sold as a one-off perpetual licence, for photographers with large libraries who don't need Lightroom/Capture One-level RAW editing.
An open-source PHP/Symfony platform unifying PIM, DAM, CMS and MDM on one codebase, for teams with in-house developers or an integrator partner rather than a marketing team wanting to self-serve.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
A team file library billed as a flat monthly fee with unlimited users, aimed at organisations where most people only need to download an approved file a few times a month.

Most common complaint
The published prices are promotional and dated; list price is roughly double
It is a broader platform than a DAM — some capability has to be built rather than switched on
Not checked
Storage ceilings are modest next to enterprise platforms, so large video libraries outgrow the tiers quickly
