Verdict
A flat-fee-per-account DAM and MAM with a free 500GB/5-user tier and unlimited paid users, for teams willing to pilot without much recent independent review evidence.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
An on-premise DAM known for deep metadata and search, for existing Portfolio users who size and maintain their own server, now under Axle AI ownership after a March 2026 acquisition.
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.

Billed on
Flat price per account by volume; the vendor states there are no per-user fees
No published price on islandora.ca — the core software is free open source ("free to use and always will be"). Paid options are hosting/installation/migration/support/training contracts sold by independent third-party service providers listed on islandora.ca/service-providers (e.g. Born-Digital, discoverygarden); islandora.ca itself does not publish their rates or billing units.
Quoted per customer; the licensing model was preserved through the change of owner
Self-hosted: no licence fee. Hosted: a user ceiling per tier

Most common complaint
On-premise is available only in the enterprise tier, whose price is not published
Not checked
It changed hands in March 2026, so anything written before that date describes it as an Extensis product
The free route is genuinely free of licence fees but moves hosting, upgrades and support onto you
