Most common complaint
Feature-level add-on pricing makes the final figure hard to anticipate before a quote
The pricing page contains neither tiers nor figures
Not one tier and not one figure on the pricing page
Windows only, so it is out of the question for a team on Macs

“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.
CELUM The pricing page contains neither tiers nor figures — ask them to answer this in writing before the trial.
Optimizely Not one tier and not one figure on the pricing page — ask them to answer this in writing before the trial.
IMatch Windows only, so it is out of the question for a team on Macs — ask them to answer this in writing before the trial.
