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.

An image and video CDN with an API-first asset library, built for fast developer integration, billed on flat monthly tiers with per-GB overage once bandwidth or storage limits are exceeded.

A CDN and edge-computing platform bundling storage, video streaming, DNS and image optimization, aimed at developers and cost-conscious teams as an alternative to larger CDN providers.

A developer-facing image and video transformation API and CDN, billed from one pooled credit balance covering storage, transformations and bandwidth together.

Most common complaint

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

Several units are metered at once: bandwidth, storage, video units and seats

Not checked

Prices are published for the API but not for the DAM, so the product being compared with a DAM still has no price

“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.
