Most common complaint
The gap between the free edition and the first paid one is wide: €200 a month
Not checked
Prices are published for the API but not for the DAM, so the product being compared with a DAM still has no price
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.
