What AB Tasty is
AB Tasty is a French-founded experience optimization company. Its platform has covered client-side A/B and multivariate testing with a visual editor, personalization and audience targeting, feature flagging and server-side experimentation, and e-commerce features such as product recommendations and search. It's used largely by retail and consumer brands, particularly in Europe.
In January 2026, Everstone Capital announced it was combining AB Tasty with Wingify, the company behind VWO. TechCrunch reported the combined company would have over $100 million in annual revenue and more than 4,000 customers. In September 2026 the business adopted Wingify as its unified brand and launched a single platform drawing on both products.
What ABFinal is
A free set of calculators and guides for planning and analyzing A/B tests. It doesn't run experiments, doesn't need an account and stores nothing.

Choosing
Pick a platform like AB Tasty when you need to run many tests and personalization campaigns with a visual editor and support, and the budget is there. As with VWO, ask how the merger affects the product you'd be buying.
Use ABFinal when you need to answer the questions around a test: is the traffic enough, how long will it take, is the split clean, and what does the result really say. It's also handy as an independent check on numbers from any platform.
