Verdict
A PIM platform with a built-in DAM module, used by manufacturing and ecommerce companies to manage product data and assets; also available as a free open-source Community Edition.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
A visually organized, board-based DAM for photo/image-heavy creative and marketing teams, with a genuinely usable free tier and a history of shifting, steep paid-tier pricing.
A self-hosted file-sync and collaboration platform some organisations stretch into asset-library duty; tagging, batch metadata editing and dynamic tag-based collections are still limited or missing.

No genuine dollar pricing is published. The vendor's package-comparison page lists four tiers: Community Edition (free, open-source, self-hosted), Growth (SaaS, shown only as "Starting at $0 Annually" with a free-trial CTA — no real recurring price disclosed), Advanced and Premium (both "Call for a quote"). No billing unit (per user, per SKU, per asset, per GB) is stated anywhere on the site for the paid tiers.
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.

The free tier is described in detail while the paid tiers are named only
It is a file platform with DAM features rather than a DAM: asset-level metadata and rights are thinner
