Verdict

A visually organized, board-based DAM for photo/image-heavy creative and marketing teams, with a genuinely usable free tier and a history of shifting, steep paid-tier pricing.

An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.

A digital asset management platform layered on Google Drive (or S3/Dropbox), for marketing, creative, and e-commerce teams organizing and sharing brand assets in place.

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.

Credits; users are not billed

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.

Flat monthly/annual subscription per plan tier (tiers differ by included user count and storage cap), plus per-additional-teammate add-on fee ($15-25/mo depending on plan) and optional paid feature add-ons (custom fields, watermarking, branding, API, CSV import, Okta SSO, etc.)

Most common complaint

The free tier is described in detail while the paid tiers are named only

Not checked

A free start exists, but the terms for moving to a paid tier are not on the page

“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.

Air The free tier is described in detail while the paid tiers are named only — 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.
