ConfigCat vs VWO

From $110 per month (Pro)

Free tier available

Plans run Free, Pro $110, Smart $325, Enterprise $900 and Dedicated $4,500 a month. Unlimited seats and unlimited flag reads on every plan, including free — unusual and genuinely valuable for wide access; paid tiers mainly raise flag, environment and product limits.

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.
