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 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.
A DAM built around search and tagging for mid-market teams, with unlimited free view-only accounts but per-seat pricing for editors that only appears after a sales quote.
Free, open-source, cross-platform photo cataloging software for large RAW libraries, with tagging, geotagging and duplicate detection, meant to pair with a separate RAW editor.

Most common complaint
It is a file platform with DAM features rather than a DAM: asset-level metadata and rights are thinner
A free start exists, but the terms for moving to a paid tier are not on the page
The tiers are named and described but cannot be compared on cost
It has no collaboration, permissions or approvals by design

“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.

Nextcloud It is a file platform with DAM features rather than a DAM: asset-level metadata and rights are thinner — ask them to answer this in writing before the trial.
Contentstack A free start exists, but the terms for moving to a paid tier are not on the page — ask them to answer this in writing before the trial.
Canto The tiers are named and described but cannot be compared on cost — ask them to answer this in writing before the trial.
digiKam It has no collaboration, permissions or approvals by design — ask them to answer this in writing before the trial.
