Choosing between CustomFit.ai and AB Tasty comes down to fit: AB Tasty is a capable experimentation tool, but CustomFit is purpose-built for D2C and Shopify brands — cart- and AOV-aware, no-code for marketers, and bundled with an AI Copilot, personalization, and feature flags in one platform.
Where many AB Tasty deployments need engineering support, custom widgets, or per-seat licensing, CustomFit gives growth teams a visual editor, 100+ ready ecommerce widgets, and usage-based pricing with unlimited users. Migration is guided — your active experiments, goals, and audiences are mapped over during onboarding, so you keep momentum instead of restarting.
Both tools run rigorous A/B and multivariate tests with solid statistics. The difference is everything around the test: CustomFit closes the loop from observation to personalized rollout, ties every experiment to real revenue, and is typically live in days rather than a multi-quarter implementation.
Most D2C teams migrate in days. CustomFit’s team maps your live AB Tasty experiments, goals, and audiences during onboarding so you don’t lose history or restart from scratch.
