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 combined PIM and DAM platform for managing product data and media, built for SMB and mid-market ecommerce brands, manufacturers, and agencies.

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 gap between the free edition and the first paid one is wide: €200 a month

Not checked

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.
