Verdict
A self-hosted, single-container photo indexer under AGPL/commercial licensing, for people who want a private on-hardware archive without Google-Photos-level AI tagging or mobile app polish.
A DAM module bundled inside the Optimizely CMS/Content Marketing Platform/DXP, for teams already on Optimizely who don't need best-of-breed asset management, bulk operations, or metadata governance.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
A file-processing API that handles uploading, transforming, and delivering video, audio, images, and documents, for developers who'd otherwise build that infrastructure in-house.

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.
GB of data processed per month (combined input + output file size); paid tiers also gate priority processing slots, collaborator seats, and max file size. Overage on the paid Startup tier billed at $1.80/GB. Enterprise tier is custom/quote-based tiered pricing with whitelabeling.

Most common complaint
The gap between the free edition and the first paid one is wide: €200 a month
Not one tier and not one figure on the pricing page

Not checked

“Not checked” means exactly that: we have not verified it, not that the platform lacks it. Every other value was read off the vendor’s own pages on the date shown on each platform page.

What to ask on the demo

One question per platform, drawn from what actually goes wrong with it — not a generic checklist. Vendors run the demo; this hands the agenda back to you.

PhotoPrism The gap between the free edition and the first paid one is wide: €200 a month — ask them to answer this in writing before the trial.
Optimizely Not one tier and not one figure on the pricing page — ask them to answer this in writing before the trial.
