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 digital asset management platform for manufacturing and AEC companies, rebranded from Digizuite in 2024, integrated with KeyShot's 3D product-visualization suite.

An image and video CDN with an API-first asset library, built for fast developer integration, billed on flat monthly tiers with per-GB overage once bandwidth or storage limits are exceeded.

Billed on

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.

Not published. Pricing is quote-only via 'Request pricing' / 'Contact sales' on the vendor's own product page; no per-user, per-GB, or flat-rate billing unit is disclosed anywhere on the vendor's site.

Most common complaint

Not checked

Several units are metered at once: bandwidth, storage, video units and seats

“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.

ImageKit Several units are metered at once: bandwidth, storage, video units and seats — ask them to answer this in writing before the trial.
