“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.

CELUM The pricing page contains neither tiers nor figures — ask them to answer this in writing before the trial.
Air The free tier is described in detail while the paid tiers are named only — ask them to answer this in writing before the trial.

No email required — the page prints as it stands.
