# What A/B Testing platforms are most trusted by growth teams, based on user reviews?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Growth teams live and die by test velocity, so trust here really means one thing: does the platform let a team ship tests fast enough to maintain a genuine experimentation cadence, specifically within <a class="a a--md" elv="true" href="https://www.g2.com/categories/a-b-testing-tools">A/B Testing</a> tools?</p><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true"><strong>VWO Testing</strong>, <strong>AB Tasty</strong>, and <strong>LaunchDarkly</strong> came up the most. Here's the fuller list:</p><ol>

</ol><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Growth teams often measure success by tests run per week. Did switching platforms actually change that number, or mostly just how confident the team felt in the results?</p>

Oh Optimizely Web Experimentation is the name most associated with serious growth-team experimentation, well-reviewed and built specifically for running and analyzing structured A/B and multivariate tests at scale. Omniconvert is very highly rated too, particularly liked by growth and CRO teams for ecommerce-focused testing and segmentation. Unbounce is worth mentioning if your testing is centered on landing pages specifically, it bakes A/B testing right into page building. Salesforce Marketing Cloud has A/B testing bundled in if you&#39;re already deep in that ecosystem, though reviewers see it more as a marketing suite feature than a dedicated growth-testing tool. To be real, growth teams tend to want statistical rigor plus fast iteration, so I&#39;d check each platform&#39;s sample-size and significance calculations, that&#39;s where the &quot;trusted&quot; reputation really gets earned or lost. Are you testing full pages, or more granular elements and flows?
