Verdict

A combined PIM and DAM platform for managing product data and media, built for SMB and mid-market ecommerce brands, manufacturers, and agencies.

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

A DAM built around search and tagging for mid-market teams, with unlimited free view-only accounts but per-seat pricing for editors that only appears after a sales quote.

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.

Tiered plans priced by SKU (product) count, not by user seat — all plans include unlimited user seats. Each tier also caps monthly AI credits, API calls/hour, and DAM file storage + CDN traffic (GB/month). Standard is free (500 SKUs, 50GB storage); Pro is $499/mo (50,000 SKUs, 750GB storage); Enterprise is custom/quote-only (unlimited SKUs, custom storage). Optional flat-fee add-ons (Product Feeds $300/mo, Brand Portals $300/mo, Product Data Sheets $200/mo) and one-time onboarding fees ($0 / $3,000 / custom).

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

Not checked

The tiers are named and described but cannot be compared on cost

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.
