Verdict
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.
An enterprise DAM bundled with workflow and creative-review tools, aimed at mid-to-large manufacturing and consumer brands needing deep Adobe/PIM/CMS/e-shop integration and partner-led setup.
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.
An image/video optimization and delivery API with a lightweight DAM layered on top, aimed at EU-based teams that want GDPR/France-hosted processing and hands-on vendor support.

Most common complaint
It is a file platform with DAM features rather than a DAM: asset-level metadata and rights are thinner
The pricing page contains neither tiers nor figures
A free start exists, but the terms for moving to a paid tier are not on the page
Three tiers described by features, none of them priced

“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.
