Verdict
A self-hosted, permission-based photo/video catalog with album hierarchies, tagging and a large plugin ecosystem, for archives and small orgs willing to maintain their own server as the library grows.
An enterprise DAM bundled with workflow and creative-review tools, aimed at mid-to-large manufacturing and consumer brands needing deep Adobe/PIM/CMS/e-shop integration and partner-led setup.
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.

Flat price per account by storage; users are unlimited
Quoted per customer
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.

“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.

Piwigo A ten per cent price rise is announced for 1 September 2026 — ask them to answer this in writing before the trial.
CELUM The pricing page contains neither tiers nor figures — ask them to answer this in writing before the trial.
