Optimizely, Contentstack, Kontainer, Uploadcare

Side by side on what we have verified on each vendor’s own pages. Where a fact was not checked, the table says so rather than leaving a blank that reads as “no”.

Most common complaint
Not one tier and not one figure on the pricing page
A free start exists, but the terms for moving to a paid tier are not on the page
Feature-level add-on pricing makes the final figure hard to anticipate before a quote
The free tier is stated as personal use only

“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.
