Verdict
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.
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.
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 developer-first file upload and CDN/media-processing API for apps, pitched as a lighter, faster-to-integrate alternative to Cloudinary for teams that don't need its full DAM/video/AI stack.

Most common complaint
The free route is genuinely free of licence fees but moves hosting, upgrades and support onto you
It has no collaboration, permissions or approvals by design
A free start exists, but the terms for moving to a paid tier are not on the page
The free tier is stated as personal use only

“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.
