Verdict
An image and video API for real-time resizing, compression, and format conversion via URL parameters, built for developers at ecommerce, media, and agency teams.
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.
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.

Consumption-based credits, sold in monthly tiers ($25–$500/mo self-serve, custom above that). Credits are spent on Management (2 credits/GB/month for stored assets), Delivery (1 credit/GB bandwidth), and Transformation (variable by operation). Per-credit rate drops as plan tier rises ($0.25 down to $0.12, monthly billing; slightly cheaper on annual commitment). Each plan also states an implied storage/bandwidth cap in GB.
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
Subscription per user per year, cheaper at volume

On-premise is available only in the enterprise tier, whose price is not published
It is a file platform with DAM features rather than a DAM: asset-level metadata and rights are thinner
