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.
A DAM built around search and tagging for mid-market teams, with unlimited free view-only accounts but per-seat pricing for editors that only appears after a sales quote.
An open-source DAM, CMS, and PIM platform combining asset, content, and product management for mid-to-large enterprises in banking, insurance, and retail.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.

Billed on
Flat price per account by volume; the vendor states there are no per-user fees
Team size and storage volume
Cloud service: billed by storage capacity (GB) plus which optional modules you select; user accounts are unlimited/uncapped. No public price list — pricing is obtained via a configurator/calculator or by requesting a quote. On-premise/hosted deployments use Free, Standard, and Enterprise license editions (feature-gated), also quote-only. A non-commercial Free Edition exists with no disclosed price.
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.
