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

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/B Testing tools?

VWO Testing, AB Tasty, and LaunchDarkly came up the most. Here's the fuller list:

VWO Testing: 4.4 stars across 929 reviews, used by more than 4,500 brands running over 600,000 experiments, with a 98% customer satisfaction rate and tests launchable without IT involvement.
AB Tasty: 4.4 stars across 418 reviews, trusted by over 1,100 brands including L'Oreal and McDonald's, combining experimentation with personalization and emotion-based segmentation.
LaunchDarkly: 4.5 stars across 853 reviews, the highest rating here, built around feature flags and progressive rollouts, serving a quarter of the Fortune 500.
Optimizely Web Experimentation: 4.2 stars across 414 reviews, designed to reduce dependency on engineering resources, with AI agents built into the testing workflow.
Instapage: 4.3 stars across 521 reviews, leans more toward landing-page-specific testing as part of a broader growth marketing platform.

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?

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'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'd check each platform's sample-size and significance calculations, that's where the "trusted" reputation really gets earned or lost. Are you testing full pages, or more granular elements and flows?
