An enterprise DAM module within Adobe Experience Manager, for large organizations managing thousands to millions of brand assets across marketing channels.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
An enterprise headless CMS and composable DXP for developer-led teams needing multi-channel content delivery, with a native asset-management module that's newer and thinly reviewed.
A digital asset management platform for enterprises, agencies, museums, and nonprofits, paired with in-house consulting and data-migration services.

No public price list; sales quote required for both packages (Prime and Ultimate). Adobe's own on-premise product description sheet lists separate license metrics per component — AEM Assets itself is licensed 'Per Instance', 'Users' are licensed 'Per User', Brand Portal is licensed 'Per Brand Portal User', and Dynamic Media/Personalized Media are licensed by 'Page Views per month' — so billing is multi-metric and only available via custom quote, not a single flat per-user or per-GB rate.
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.
Quoted per customer

Plans are differentiated by number of admin users, storage (TB), and number of portals (e.g. Essential: 5 admin users/1TB; Signature: 20 admin users/2TB/3 portals; Premium: 50 admin users/5TB/5 portals); exact per-unit or per-tier prices are not published, visitors must request a consult.
