Run rigorous A/B tests and personalize every visit on Shopify or any storefront โ no engineers required.
AB Tasty is a French-headquartered experimentation and personalization platform that targets mid-market and enterprise digital teams โ particularly European retail and media brands โ with strong feature flags, widget-based personalization, and engagement tools like push notifications. CustomFit.ai is purpose-built for D2C ecommerce brands, with Shopify-native integration, out-of-the-box revenue metrics, and AI-powered optimization at a fraction of AB Tasty's typical contract size. For a Shopify brand that wants to run A/B tests and personalize product pages without a developer or an enterprise contract, CustomFit.ai is the faster, more cost-effective choice. For a European enterprise with multi-surface experimentation needs and an existing AB Tasty relationship, AB Tasty offers genuine breadth.

CustomFit.ai's Shopify install takes under 5 minutes with no coding. For non-Shopify sites, the JS snippet goes in your <head> and tracks immediately. The visual editor is deliberately simple โ marketers describe it as approachable from day one without training.
AB Tasty offers a no-code visual editor as well, with a widget library for adding elements like pop-ups, banners, and countdown timers directly to pages. Setup for basic tests is accessible. For more advanced features โ feature flag rollouts, server-side tests, or SDK integration โ developer involvement is needed. AB Tasty's onboarding for enterprise accounts includes a dedicated CSM, which helps, but adds lead time before your first test is live.
CustomFit.ai covers A/B tests, multivariate tests, split URL tests, and multi-page funnel tests with no concurrent test limits on paid plans. AI dynamic traffic allocation continuously shifts visitors toward winning variants, reducing the time to reach statistical significance. Audience targeting uses 1000+ attributes including purchase history, cart state, behavioral signals, and predictive buyer intent. Indian D2C brands like Bellavita and Kapiva used this targeting to run product-page tests segmented by city tier and returning-buyer status.
AB Tasty's A/B testing capabilities are comprehensive: A/B, multivariate, split URL, and server-side tests. Its Autopilot mode uses multi-armed bandit logic to automatically allocate traffic โ similar to CustomFit.ai's AI allocation. AB Tasty also includes native support for progressive rollouts and feature flags, which are useful for product teams shipping new features gradually. AB Tasty's audience builder is powerful, though its depth requires time to configure.
CustomFit.ai's personalization layer is included at all plan levels. Using 1000+ targeting attributes, you can serve personalized product page layouts, homepage banners, and CTAs to segments built around purchase history, session behavior, device type, and AI-predicted intent. No separate module or upgrade is required.
AB Tasty's personalization product ("EmotionsAI") goes beyond rule-based targeting โ it uses an emotional state engine that categorizes visitors into affective profiles (reassurance-seeking, novelty-seeking, etc.) and adjusts content tone accordingly. This is a genuinely differentiated feature for brands that want psychographic personalization rather than purely behavioral targeting. EmotionsAI is an add-on, and this capability comes at additional cost.
CustomFit.ai reports on revenue per visitor (RPV), average order value (AOV), conversion rate, and add-to-cart rate as primary metrics. For Shopify brands, these pull from order data automatically with no custom event setup. Statistical significance is shown per test in a clean dashboard.
AB Tasty's reporting covers a wide range of goal types and integrates with major analytics platforms. Its dashboards are well-designed and support multiple concurrent metrics per test. AB Tasty also offers audience insights that surface behavior patterns beyond experiment results โ useful for hypothesis generation. The depth is real but adds complexity for teams that just want to know "did this test increase revenue?"

AB Tasty does not publish pricing. Third-party reviews and vendor comparison sites indicate contracts typically start in the mid-four-figures per month range for mid-market customers. CustomFit.ai's transparent, self-serve pricing makes it significantly more accessible to growth-stage D2C brands. For Indian D2C brands, CustomFit.ai's Starter plan at approximately โน8,300/month is a meaningful budget advantage.
