Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

What drives the bill

The metric that actually scales your invoice.

Quote-based annual contracts priced by traffic volume, now sold as part of the merged Wingify platform.

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.
