Verdict
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
A cloud service for storing, resizing, optimizing and delivering images via API and CDN, aimed at developers building web and mobile apps that handle images at scale.
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 Windows-only photo cataloging tool for large image libraries (50,000+ files), built by a single developer, sold as a one-time perpetual licence instead of a subscription.

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.
Storage ($5 / 100,000 images stored / month), delivery ($1 / 100,000 images delivered / month), and transformations (first 5,000 unique transformations/month free, then $0.50 / 1,000 unique transformations/month). A unique transformation is billed per distinct parameter combination (e.g. same image at 100x100 and 200x200 counts as two). Storage/delivery charges apply only to images hosted in Cloudflare Images; transforming externally-hosted images is billed only under transformations.
