VWO vs Convert Experiences

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.

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.

Priced only on tested traffic — unlimited experiments, domains and users at every tier. Growth is $299/month paid annually ($399 monthly) for 100k tested users; Pro starts around $420/month annually.

Strengths

  • Observation and experimentation in one place shortens the hypothesis loop.
  • Visual editor is capable and marketer-friendly.
  • Cheaper than Optimizely at comparable traffic.
  • Unlimited experiments and seats, so nobody rations testing to save licence cost.
  • Serious privacy posture with EU hosting and no data resale.
  • Transparent, published pricing.

Limitations

  • Module-based pricing means the useful configuration costs much more than the headline.
  • Client-side flicker on complex single-page applications.
  • Server-side capability lags the flag-first platforms.
  • Client-side only — no server-side experimentation.
  • No feature-flag capability.
  • Smaller vendor with a modest ecosystem.

Best for

Conversion-optimisation teams that want testing and behavioural insight from one vendor.

Mid-sized e-commerce teams that want unlimited client-side testing with clean privacy handling.

All of these integrate with: Google Analytics, Segment, Shopify, Mixpanel.
