Verdict

A headless CMS with a built-in asset library for images and files, not a standalone DAM — it lacks file versioning, rights/expiry management and native video transcoding.

An open-licence, self-hosted DAM for teams with in-house server admin capability, trading a free licence for the time to run upgrades, tune dependencies and troubleshoot it themselves.

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 product experience management (PXM) platform for brands and manufacturers that centralizes and syndicates product data to retail and ecommerce channels.

The free route is genuinely free of licence fees but moves hosting, upgrades and support onto you

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.
