VWO and AB Tasty are both mid-market CRO and experimentation platforms that compete for the same audience: marketing and CRO teams at digital businesses who need A/B testing, personalisation, and behaviour analytics in one place. VWO has a stronger integrated analytics suite (heatmaps, session recordings, surveys) and is particularly popular in South Asia and India. AB Tasty โ which merged with Kameleoon in 2024 โ has strengthened its personalisation and feature management capabilities. Post-merger, AB Tasty/Kameleoon positions itself more heavily at enterprise personalisation. For D2C brands running standard conversion optimisation, VWO remains the more complete, accessible platform.
VWO (Visual Website Optimizer) is a CRO platform built by Wingify, an Indian company. It offers A/B testing, multivariate testing, personalisation, heatmaps, session recordings, surveys, funnels, and a visual editor for no-code test creation. VWO serves mid-market and enterprise brands across ecommerce, SaaS, and media. Pricing starts at around $199/month for the Testing plan (50,000 monthly tested users), with broader platform packages available at higher tiers.
AB Tasty is a French-origin CRO and personalisation platform founded in 2013. In 2024, AB Tasty and Kameleoon โ a fellow French experimentation platform โ merged their products and organisations. The combined entity offers web and mobile A/B testing, feature flagging, AI-driven personalisation, and audience targeting. Post-merger pricing is enterprise-oriented; AB Tasty does not publish list prices, and custom contracts typically start around $30,000โ$60,000/year.

VWO offers transparent, tiered pricing starting at $199/month โ accessible for growing D2C brands without requiring a sales conversation. The Testing plan at this level covers 50,000 monthly tested users, sufficient for a mid-size store.
AB Tasty, post-merger with Kameleoon, has moved upmarket. Their pricing is entirely custom and sales-led. Published estimates suggest entry-level contracts in the $30,000โ$75,000/year range, with larger personalisation deployments going significantly higher. This is a fundamental access gap: VWO is accessible to D2C brands doing โน10โ100 crore in revenue; AB Tasty/Kameleoon effectively prices out companies below โน200โ500 crore.
The merger has strengthened AB Tasty technically but made it less accessible to the mid-market it previously served. Some former AB Tasty mid-market customers have migrated to VWO or other platforms as a result.
The AB Tasty and Kameleoon merger combined two distinct product philosophies:
Post-merger, the combined platform has gained feature flagging (Kameleoon's strength) and broader personalisation AI capabilities. AB Tasty's marketer-friendly UI has been retained but the overall platform is now more complex.
For D2C brands evaluating AB Tasty today, the relevant questions are: (1) Has the pricing moved beyond what your budget allows? (2) Do you need the feature flagging and server-side capabilities the merger added, or were you primarily using AB Tasty for standard web A/B testing?
Both platforms handle standard web A/B testing well โ visual editor, URL targeting, audience segmentation, statistical reporting.
VWO's statistical engine (SmartStats) uses Bayesian statistics, which gives probability-based results rather than binary pass/fail significance thresholds. This is generally more actionable for ecommerce teams who need to make decisions before reaching arbitrary p-values.
AB Tasty offers both frequentist and Bayesian modes, giving teams statistical flexibility. Kameleoon's full-stack testing capabilities (now part of the merged entity) are enterprise-grade for server-side feature experimentation.
This is a meaningful difference: VWO includes heatmaps, session recordings, and surveys as part of its platform (either bundled or as add-ons). AB Tasty does not. If you want to understand why users aren't converting before you test solutions, VWO gives you the qualitative tools alongside the testing tools.
AB Tasty's EmotionsAI personalisation โ which segments users by emotional profile and adapts content accordingly โ is an interesting differentiator that VWO doesn't directly replicate. Whether it translates into measurable conversion lift for D2C ecommerce (versus content or media brands) is debated.
Both VWO and AB Tasty are general-purpose platforms that work on any website. For D2C brands specifically on Shopify, it's worth considering whether a Shopify-native testing platform might be a better fit โ particularly if the general platforms' pricing or complexity is overkill.
CustomFit.ai is purpose-built for D2C and ecommerce brands on Shopify. It provides a no-code visual editor, A/B testing, personalisation, and conversion rate reporting in a Shopify-native environment โ at a fraction of VWO's cost and without the post-merger complexity of AB Tasty. If you're evaluating VWO or AB Tasty for your D2C stack, try CustomFit.ai free for 14 days before committing to a larger contract. It handles the same A/B testing use cases for ecommerce without the enterprise overhead.
Did AB Tasty and Kameleoon fully merge their products? The companies merged in 2024 and are consolidating their products. The integration of Kameleoon's feature flagging and server-side testing into AB Tasty's platform is ongoing.
Is VWO still owned by Wingify? Yes. VWO is built and operated by Wingify, an independent Indian B2B SaaS company headquartered in New Delhi.
Can VWO replace Google Optimize? Yes. VWO is one of the most common migrations from Google Optimize, which shut down in September 2023. VWO offers similar or better functionality at comparable price points.
Does AB Tasty work in India? AB Tasty has enterprise customers in India but does not have a local support team. VWO (Wingify) is India-based with local support.
What stats engine does VWO use? VWO uses SmartStats, a Bayesian statistical engine that provides probability-based decision-making rather than traditional p-value significance testing.
