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 flat-fee-per-account DAM and MAM with a free 500GB/5-user tier and unlimited paid users, for teams willing to pilot without much recent independent review evidence.

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 Nordic/European DAM, with optional PIM, aimed at mid-market brand, retail and ecommerce teams wanting fast onboarding without heavy IT involvement, backed by a 30-day no-commitment trial.

Most common complaint

The free tier is stated as personal use only

On-premise is available only in the enterprise tier, whose price is not published

Not checked

Feature-level add-on pricing makes the final figure hard to anticipate before a quote

“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.
