Verdict

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.

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 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 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.

Most common complaint

The free tier is stated as personal use only

Not checked

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

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.
