VWO review

From VWO to Wingify

VWO (Visual Website Optimizer) is the testing product of Wingify, the Indian software company Paras Chopra and Sparsh Gupta co-founded in 2010. Everstone Capital bought a majority stake in January 2025. On January 20, 2026, Wingify announced a merger with the French testing company AB Tasty, and in September 2026 the combined business launched under the Wingify name. vwo.com now redirects to wingify.com. Wingify said existing contracts, pricing, service levels and support stay the same, and that the product lines will become more connected over time.

Web testing

The core product is web experimentation: A/B, split URL and multivariate tests, built in a point-and-click visual editor or a code editor. Every plan includes unlimited experiments, variations and metrics. Pro adds guardrail metrics, which can switch off an underperforming variation, sample ratio mismatch detection, multivariate tests and cross-domain tests. Enterprise adds self hosting, approval workflows, mutually exclusive groups and SSO.

Reporting and stats

Reports run on a Bayesian engine by default. Wingify also lists fixed-horizon tests and sequential testing, which adjusts for peeking, as options. With Wingify's behavior analytics, heatmaps and session recordings can show inside campaign reports. You can filter results by device, traffic source, UTM parameters, geography and custom segments.

Wingz AI

Wingz is the AI layer across the platform. For experiments, a hypothesis agent turns data into test ideas and drafts variations, an experiment agent prepares audiences, variations and metrics, and an insight agent looks for segments that behaved differently. Wingify says nothing goes live without your approval. Wingz Core comes with every paid plan. Wingz Advanced and credit packs are paid extras.

Revenue tracking

VWO can report revenue, average order value and other value metrics, but you set it up. The documented method is a JavaScript snippet on your thank-you page that passes the order total, placed in the page or through a tag manager. The Shopify integration sends which campaign and variation a visitor saw into Shopify's event stream. It doesn't track goals or revenue by itself.

Server-side and apps

Feature Experimentation adds feature flags and server-side tests through open-source SDKs, which Wingify lists in more than 10 languages across front-end, back-end, mobile and OTT.

Who it suits

VWO suits marketing and product teams that want testing, behavior analytics and personalization from one vendor, and have someone to own the program. It suits small teams less well. Prices are quote-only and based on monthly active users, and a person still decides what to test and signs off each AI suggestion.
