Verdict
A file upload, transformation, and delivery API with a drop-in picker for 20+ sources, for developers adding file handling to web and mobile apps.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
An image/video optimization and delivery API with a lightweight DAM layered on top, aimed at EU-based teams that want GDPR/France-hosted processing and hands-on vendor support.
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.

Billed on
Monthly subscription tiers with bundled resource allowances (bandwidth in GB, uploads counted per file, transformations per file/image operation, storage in GB, number of team members), plus per-unit overage fees once a tier's allowance is exceeded (e.g. Start plan overage is $0.2/GB bandwidth).
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.

Three tiers described by features, none of them priced
It is a file platform with DAM features rather than a DAM: asset-level metadata and rights are thinner
