Most common complaint
A free start exists, but the terms for moving to a paid tier are not on the page
Not checked
The pricing page contains neither tiers nor figures
Not checked

“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.

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.
CELUM The pricing page contains neither tiers nor figures — ask them to answer this in writing before the trial.

No email required — the page prints as it stands.
