Best A/B testing tool — according to AI
We asked AI assistants 6 questions a real buyer would ask about A/B testing tools — “what's the best?”, “what would you recommend for a small business?”, “what's a good affordable option?” — and counted which products the AI actually named. This is what the models recommend today (last checked October 5, 2026).
| # | Product | AI answers mentioning it |
|---|---|---|
| 1 | VWO“best all-around value. A/B testing plus heatmaps, session recordings, and surveys in one platform.” | 6/6 |
| 2 | Optimizely“still the enterprise standard. Strong stats engine, good integrations, and solid for complex multi-page experiments.” | 5/6 |
| 3 | AB Tasty“strong for personalization and experimentation, especially if you're doing more than simple button-color tests.” | 5/6 |
| 4 | Google Optimize“shut down in September 2023, so ignore it.” | 5/6 |
| 5 | Convert.com“a favorite for privacy-conscious teams. Strong GDPR/CCPA posture, no data leakage issues, and it's fast.” | 4/6 |
| 6 | PostHog“if you're already using PostHog for analytics, its experimentation feature is convenient and cheap.” | 4/6 |
| 7 | GrowthBook“open-source and self-hostable. Great if you want warehouse-native experimentation.” | 3/6 |

Methodology & honesty notes
Counts come from asking an AI model 6 standardized buyer questions and extracting the products it names — model knowledge, not live web search, and small samples move week to week. Treat position as directional, not a verdict. Not sponsored; no product can pay to appear here.
