Verdict
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.
A cloud portfolio and image-storage platform for individual photographers, with client galleries and built-in print/licensing sales.
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.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.

Billed on
Bandwidth, storage and user seats, with published per-unit rates above the limits
Quote-only. Priced per named "Library Seat" (2-5 seats depending on tier, custom for Enterprise) plus a storage allotment per tier (1TB-5TB, custom for Enterprise) and a cap on "Advanced Integrations" (0 to unlimited). Unlimited invited/contributor users and unlimited Social Content Publisher seats included on all/most tiers. Annual or monthly billing toggle shown on the pricing page, but no dollar amounts are published — all tiers show a "Get Pricing" CTA to a demo/sales call.
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.

Most common complaint
Several units are metered at once: bandwidth, storage, video units and seats
Not checked
A free start exists, but the terms for moving to a paid tier are not on the 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.

ImageKit Several units are metered at once: bandwidth, storage, video units and seats — ask them to answer this in writing before the trial.
Contentstack A free start exists, but the terms for moving to a paid tier are not on the page — ask them to answer this in writing before the trial.
