Verdict
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-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
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-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.

Quoted per customer; the licensing model was preserved through the change of owner
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.
Flat price per account by volume; the vendor states there are no per-user fees
Self-hosted: no licence fee. Hosted: a user ceiling per tier

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