Verdict
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
A CDN and edge-computing platform bundling storage, video streaming, DNS and image optimization, aimed at developers and cost-conscious teams as an alternative to larger CDN providers.
A self-hosted, permission-based photo/video catalog with album hierarchies, tagging and a large plugin ecosystem, for archives and small orgs willing to maintain their own server as the library grows.
A developer-facing image and video transformation API and CDN, billed from one pooled credit balance covering storage, transformations and bandwidth together.

A ten per cent price rise is announced for 1 September 2026
Prices are published for the API but not for the DAM, so the product being compared with a DAM still has no price

“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.

Piwigo A ten per cent price rise is announced for 1 September 2026 — ask them to answer this in writing before the trial.
Cloudinary Prices are published for the API but not for the DAM, so the product being compared with a DAM still has no price — ask them to answer this in writing before the trial.
