Verdict
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 cloud portfolio and image-storage platform for individual photographers, with client galleries and built-in print/licensing sales.
An open-licence, self-hosted DAM for teams with in-house server admin capability, trading a free licence for the time to run upgrades, tune dependencies and troubleshoot it themselves.
Free, open-source, cross-platform photo cataloging software for large RAW libraries, with tagging, geotagging and duplicate detection, meant to pair with a separate RAW editor.

Most common complaint
It is a broader platform than a DAM — some capability has to be built rather than switched on
Not checked
The free route is genuinely free of licence fees but moves hosting, upgrades and support onto you
It has no collaboration, permissions or approvals by design
