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 file upload, transformation, and delivery API with a drop-in picker for 20+ sources, for developers adding file handling to web and mobile apps.

A digital asset management platform for enterprises, agencies, museums, and nonprofits, paired with in-house consulting and data-migration services.

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.

Seats, content types and volume

Monthly subscription tiers with bundled resource allowances (bandwidth in GB, uploads counted per file, transformations per file/image operation, storage in GB, number of team members), plus per-unit overage fees once a tier's allowance is exceeded (e.g. Start plan overage is $0.2/GB bandwidth).

Not disclosed publicly. Plans are differentiated by number of admin users, storage (TB), and number of portals (e.g. Essential: 5 admin users/1TB; Signature: 20 admin users/2TB/3 portals; Premium: 50 admin users/5TB/5 portals); exact per-unit or per-tier prices are not published, visitors must request a consult.

Not checked

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

“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.
