Verdict
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
An API-first, developer-configurable content platform with DAM features, built for enterprise teams (100+ users) with in-house developers, not a low-code tool for non-technical editors.
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.
A developer-facing image and video transformation API and CDN, billed from one pooled credit balance covering storage, transformations and bandwidth together.

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.

Most common complaint
Not checked
No prices, and no explicit confirmation of on-premise on the product page
It changed hands in March 2026, so anything written before that date describes it as an Extensis product
Prices are published for the API but not for the DAM, so the product being compared with a DAM still has no price
