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.

A self-hosted file-sync and collaboration platform some organisations stretch into asset-library duty; tagging, batch metadata editing and dynamic tag-based collections are still limited or missing.

A DAM and PIM platform for mid-sized and enterprise companies with complex product data, not built for small teams.

An image and video API for real-time resizing, compression, and format conversion via URL parameters, built for developers at ecommerce, media, and agency teams.

Subscription per user per year, cheaper at volume

not disclosed — vendor states pricing is individually configured based on feature scope, integrations, hosting, and services; no per-user/per-GB/flat/credit unit is published

Consumption-based credits, sold in monthly tiers ($25–$500/mo self-serve, custom above that). Credits are spent on Management (2 credits/GB/month for stored assets), Delivery (1 credit/GB bandwidth), and Transformation (variable by operation). Per-credit rate drops as plan tier rises ($0.25 down to $0.12, monthly billing; slightly cheaper on annual commitment). Each plan also states an implied storage/bandwidth cap in GB.

Most common complaint

The calculator shows what drives the price without showing the price

It is a file platform with DAM features rather than a DAM: asset-level metadata and rights are thinner

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.
