How these comparisons are made.
Verifiable, dated facts, with shared features stated as such.
- Sources
- Official sources only: the vendors’ own pages (documentation, pricing, subprocessor lists, legal notices, and app listings) and, for the Dynamic Yield acquisition, a Mastercard filing with the SEC. No reviews or third-party articles.
- Date
- AB Tasty, Kameleoon, VWO, and Optimizely: pages accessed November 7, 2026. Adobe Target, Dynamic Yield, Convert, Varify.io, Omniconvert, Intelligems, Shoplift, GrowthBook, PostHog, Statsig, Eppo, LaunchDarkly, and Amplitude: pages accessed November 11, 2026. Documentation changes, so a point may have changed since.
- Quotes
- Every statement about a competitor links to its page, with the quote in its original language.
- “Not mentioned”
- Nothing was found in the vendor’s public documentation, which does not prove a feature is missing.
- Shared features
- When a competitor does the same as Probant (sequential testing, stepped rollouts, hosting in Europe…), the page says so.
- Wingify
- AB Tasty and VWO merged under the Wingify brand (announced January 20, 2026), which states that it keeps running both platforms. Each has its own page.
- Acquisitions
- Statsig was acquired by Amplitude, and Eppo by Datadog, which sells it as Datadog Experiments. Their pages say so at the top, with sources.
