About

VWO

VWO is an all-in-one conversion rate optimization and experimentation platform built for marketing, product, and CRO teams who want A/B testing, behavioral analytics, and personalization in a single tool without enterprise-level complexity or pricing.

It is primarily used by digital marketers, product managers, and CRO practitioners at SMB-to-mid-market companies who need to run experiments independently without heavy engineering involvement, and want built-in heatmaps and session recordings to inform test hypotheses

Teams choose VWO for its visual editor that enables non-technical users to create tests without code; its VWO Insights module that provides heatmaps, session recordings, and surveys natively alongside testing; its AI Copilot that suggests experiment ideas based on behavioral data; and its server-side and feature flag capabilities for engineering teams that need full-stack testing.

Note: VWO and AB Tasty completed a corporate merger under Everstone Capital in late 2025 — they remain separate products but share a parent company. VWO free Starter plan was significantly restricted in late 2025. Paid plans start around $198/month billed annually and scale with monthly tracked users.

Choose VWO if you are a mid-market CRO or product team that wants A/B testing, heatmaps, and personalization in one platform without enterprise pricing or a sales process. Published pricing from ~$198/mo (annual); restricted free Starter plan available.

Note the late-2025 merger with AB Tasty under Everstone Capital — ask about long-term pricing guarantees before committing.

Choose Optimizely if you have a mature, dedicated experimentation program at an enterprise organization with the budget, technical resources, and team size to justify the investment. Best for companies running 30+ tests per quarter with dedicated CRO headcount. Starts ~$36,000/year (sales required; no published pricing). Avoid it if you are a small or mid-market team — the budget barrier and implementation complexity make it the wrong tool below enterprise scale.

Before you run the test, do you know what to test?

VWO and Optimizely are both built for the moment after you have decided what to test. You have a hypothesis, you build the variant, you run the experiment, you read the result. Both tools handle that process well — at very different price points.

But most teams spend more time deciding what to test than actually running tests. Lucky Orange Discovery AI is built for that earlier question. It analyzes your session data continuously and answers plain-language questions about what is blocking your users — so your next experiment hypothesis comes from evidence, not intuition. You do not need to run a test to find out where the friction is.

Ask questions like:

  • Which elements on the pricing page are getting interaction from users who do not convert?

  • What are visitors doing on the homepage in the 30 seconds before they leave?

  • Where in the checkout flow do returning visitors drop off more than new visitors?
