AB Tasty: sovereignty score and 8 European alternatives

AB Tasty is an experimentation platform for marketers, product teams and developers. It supports client-side tests for web changes, server-side tests for back ends and APIs, and feature flags for controlled rollouts. Teams can set up A/B, multivariate and split-URL tests, define audiences and goals, follow results in dashboards and connect to analytics and data platforms. It is delivered as SaaS.

AB Tasty is based in Paris. In January 2026 the company combined with Wingify, the company behind VWO; reports describe this as either an acquisition or a merger. Wingify's majority shareholder is Everstone, a Singapore-based private equity firm. Ultimate ownership may therefore sit outside the EU, which is relevant to your CLOUD Act assessment. Wingify reports data centres in the US, the EU and India; which region applies to AB Tasty customers depends on your contract and should be confirmed with the vendor. The software is not open source.

Why digital sovereignty matters with AB Tasty

AB Tasty is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

AB Tasty hosts data outside the EU (EU only). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

AB Tasty is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs AB Tasty together with your other vendors and gives a total score, a heatmap and the main risk drivers.
