Most common complaint
Feature-level add-on pricing makes the final figure hard to anticipate before a quote
A free start exists, but the terms for moving to a paid tier are not on the page
A page titled pricing that contains a benefit calculator instead of prices
It has no collaboration, permissions or approvals by design

“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.

Kontainer Feature-level add-on pricing makes the final figure hard to anticipate before a quote — ask them to answer this in writing before the trial.
Contentstack A free start exists, but the terms for moving to a paid tier are not on the page — ask them to answer this in writing before the trial.
OpenAsset A page titled pricing that contains a benefit calculator instead of prices — ask them to answer this in writing before the trial.
