Verdict

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.

A visually organized, board-based DAM for photo/image-heavy creative and marketing teams, with a genuinely usable free tier and a history of shifting, steep paid-tier pricing.

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.

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.

Most common complaint

It has no collaboration, permissions or approvals by design

The free tier is described in detail while the paid tiers are named only

Not checked

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

“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.
