Verdict
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
A DAM offered as both cloud and on-premise, aimed at small-to-mid teams that want fast metadata-driven search over large asset libraries and want files to stay on their own infrastructure.
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.
A self-hosted file-sync and collaboration platform some organisations stretch into asset-library duty; tagging, batch metadata editing and dynamic tag-based collections are still limited or missing.

Most common complaint

Like the platforms it competes with, it asks for a form submission before naming a price
It is a broader platform than a DAM — some capability has to be built rather than switched on
It is a file platform with DAM features rather than a DAM: asset-level metadata and rights are thinner
