Kameleoon vs VWO

From $495 per month (PBX Starter: 10 experiments, 50k tested visitors)

Free tier available

Kameleoon now publishes an entry price. Above Starter it is priced by traffic and modules on a custom quote.

Priced by monthly tracked users across modules, so buying testing plus insights raises the total substantially. The Wingify rebrand has moved pricing behind Growth/Pro/Enterprise tiers without published figures — get a quote rather than relying on an old VWO list price.
