Convert Experiences vs VWO

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.

Entry price

From $299 per month (Growth, paid annually, 100k tested users; $399 monthly)

What drives the bill

The metric that actually scales your invoice.

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.

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.

Strengths

  • 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.
  • Observation and experimentation in one place shortens the hypothesis loop.
  • Visual editor is capable and marketer-friendly.
  • Cheaper than Optimizely at comparable traffic.

Limitations

  • Client-side only — no server-side experimentation.
  • No feature-flag capability.
  • Smaller vendor with a modest ecosystem.
  • 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.

Best for

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

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

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