Verdict

A brand-guidelines and asset portal for mid-market marketing teams, with a genuine free tier that covers a branded guidelines page but not the full asset library or workflow tools.

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.

A self-hosted, permission-based photo/video catalog with album hierarchies, tagging and a large plugin ecosystem, for archives and small orgs willing to maintain their own server as the library grows.

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

A ten per cent price rise is announced for 1 September 2026

“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.
