Verdict

A disk-native photo cataloguer and batch editor sold as a one-off perpetual licence, for photographers with large libraries who don't need Lightroom/Capture One-level RAW editing.

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.

A cloud service for storing, resizing, optimizing and delivering images via API and CDN, aimed at developers building web and mobile apps that handle images at scale.

An open-licence, self-hosted DAM for teams with in-house server admin capability, trading a free licence for the time to run upgrades, tune dependencies and troubleshoot it themselves.

Billed on

One-off perpetual licence; a cloud subscription is sold separately

Quoted per customer

Storage ($5 / 100,000 images stored / month), delivery ($1 / 100,000 images delivered / month), and transformations (first 5,000 unique transformations/month free, then $0.50 / 1,000 unique transformations/month). A unique transformation is billed per distinct parameter combination (e.g. same image at 100x100 and 200x200 counts as two). Storage/delivery charges apply only to images hosted in Cloudflare Images; transforming externally-hosted images is billed only under transformations.

Self-hosted: no licence fee. Hosted: a user ceiling per tier

Most common complaint

The published prices are promotional and dated; list price is roughly double

The pricing page contains neither tiers nor figures

Not checked

The free route is genuinely free of licence fees but moves hosting, upgrades and support onto you

“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.
