I'm building an ecommerce site and need a tool for A/B testing checkout and product pages

For ecommerce A/B testing on product and checkout pages, good options are:

Best all-around

• Optimizely — powerful experimentation platform, strong targeting, good for product/checkout testing, but pricier.
• VWO — easier to use than Optimizely, solid for A/B testing, heatmaps, and conversion tracking.

Best if you want simpler/cheaper

• Convert — good privacy-friendly A/B testing with solid features for ecommerce.
• Google Optimize alternatives — since Optimize is discontinued, look at GrowthBook or Statsig if you want more technical control.

Best for product analytics + experiments

• PostHog — combines feature flags, experiments, and analytics; great if you want one tool for dev-driven testing.
• Statsig — strong for feature flags and experimentation, especially if you have engineering resources.

Best for Shopify / ecommerce-focused teams

• Intelligems — built specifically for ecommerce and pricing/checkout experimentation.
• Dynamic Yield — personalization + A/B testing, strong for ecommerce merchandising.

What to look for

For checkout and product pages, make sure the tool supports:

• Flicker-free testing
• Feature flags for checkout logic
• Reliable revenue tracking
• Server-side experiments for checkout
• Audience segmentation
• Statistical significance / confidence reporting
• Easy integration with your cart/checkout stack

Quick recommendation

• If you want easy + powerful: VWO
• If you want enterprise-grade: Optimizely
• If you want dev-friendly + analytics: PostHog or Statsig
• If you’re on Shopify: Intelligems

If you want, I can also recommend the best tool based on your stack:

• Shopify / WooCommerce / custom
• budget
• whether you need checkout testing or just product pages
