Verdict
A self-hosted, single-container photo indexer under AGPL/commercial licensing, for people who want a private on-hardware archive without Google-Photos-level AI tagging or mobile app polish.
A developer-facing image and video transformation API and CDN, billed from one pooled credit balance covering storage, transformations and bandwidth together.
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 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.

Most common complaint
The gap between the free edition and the first paid one is wide: €200 a month
Prices are published for the API but not for the DAM, so the product being compared with a DAM still has no price
A free start exists, but the terms for moving to a paid tier are not on the page
The pricing page contains neither tiers nor figures

“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.
