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 DAM built around search and tagging for mid-market teams, with unlimited free view-only accounts but per-seat pricing for editors that only appears after a sales quote.

An open-source DAM, CMS, and PIM platform combining asset, content, and product management for mid-to-large enterprises in banking, insurance, and retail.

An image and video API for real-time resizing, compression, and format conversion via URL parameters, built for developers at ecommerce, media, and agency teams.

Team size and storage volume

Cloud service: billed by storage capacity (GB) plus which optional modules you select; user accounts are unlimited/uncapped. No public price list — pricing is obtained via a configurator/calculator or by requesting a quote. On-premise/hosted deployments use Free, Standard, and Enterprise license editions (feature-gated), also quote-only. A non-commercial Free Edition exists with no disclosed price.

Consumption-based credits, sold in monthly tiers ($25–$500/mo self-serve, custom above that). Credits are spent on Management (2 credits/GB/month for stored assets), Delivery (1 credit/GB bandwidth), and Transformation (variable by operation). Per-credit rate drops as plan tier rises ($0.25 down to $0.12, monthly billing; slightly cheaper on annual commitment). Each plan also states an implied storage/bandwidth cap in GB.

Not checked

“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.
