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.
An image and video CDN with an API-first asset library, built for fast developer integration, billed on flat monthly tiers with per-GB overage once bandwidth or storage limits are exceeded.

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
Several units are metered at once: bandwidth, storage, video units and seats
