Concepts referenced in this article, defined.
Run rigorous A/B tests and personalize every visit on Shopify or any storefront โ no engineers required.
Convert.com is a well-regarded A/B testing platform with a strong reputation in the CRO agency community, known for its privacy-first approach, extensive integration options, and fair pricing for traffic volume. CustomFit.ai is purpose-built for D2C ecommerce brands, with Shopify-native integration, native revenue metric tracking, and AI-powered optimization that Convert.com does not offer. For a CRO agency managing client accounts or a mid-market company that needs deep analytics integrations, Convert.com is a solid choice. For a Shopify D2C brand that wants fast setup, out-of-the-box revenue metrics, and AI-driven optimization without developer involvement, CustomFit.ai has a clear advantage.

CustomFit.ai's Shopify install is one click from the App Store. For other platforms, the JS snippet installs in under 10 minutes. The visual editor is deliberately straightforward โ described by users as intuitive from day one. Revenue tracking for Shopify is automatic; no goal configuration needed.
Convert.com uses a snippet-based installation and a visual editor that CRO practitioners find reliable and precise. Convert has historically been a favorite among CRO agencies for its stability and clean codebase. Setup for basic A/B tests is accessible to non-developers; more complex configurations (JavaScript experiments, server-side tests, custom revenue tracking) require developer input or CRO expertise. Convert.com's UI is functional but more technical in feel compared to CustomFit.ai's consumer-friendly interface.
CustomFit.ai covers A/B tests, multivariate tests, split URL tests, and funnel experiments. AI dynamic traffic allocation shifts visitors toward winning variants during the test, reducing time to statistical significance without sacrificing validity. Targeting uses 1000+ attributes including purchase history, behavioral signals, predictive buyer intent, and ecommerce-specific data like cart value and product affinity.
Convert.com's A/B testing capabilities are comprehensive and technically precise: A/B, multivariate, split URL, and multi-page tests. Convert uses frequentist and Bayesian statistical options, giving experienced CRO practitioners control over their statistical methodology. Its audience targeting is thorough, with integrations into dozens of analytics and data platforms. Convert's traffic allocation does not include AI-driven dynamic shifting โ it uses traditional fixed-split or manual adjustments. For agencies running methodologically rigorous tests for clients, Convert's controls are an asset. For D2C brands that want AI to optimize traffic automatically, CustomFit.ai's approach is more hands-off.
CustomFit.ai's personalization uses 1000+ consumer-oriented targeting attributes and AI-predicted purchase intent to serve differentiated content to audience segments. This is available on all paid plans without additional modules. Brands like Bellavita (11% CVR uplift) used geo and behavioral targeting to serve personalized product page content.
Convert.com focuses primarily on A/B testing and does not offer native personalization in the same sense as CustomFit.ai. You can build targeted experiments for specific audience segments, but there is no standalone personalization engine that continuously serves differentiated content outside of active experiments. For ongoing personalization (not just test-driven), CustomFit.ai is the stronger option.
CustomFit.ai tracks revenue per visitor (RPV), average order value (AOV), add-to-cart rate, and conversion rate natively from Shopify data. Reporting is focused on revenue impact with clear significance indicators.
Convert.com's reporting is detailed and integrates with Google Analytics 4, Heap, Mixpanel, Segment, and 100+ other tools. For CRO agencies that need to pull experiment data into client-specific dashboards, Convert's integration depth is excellent. Convert also provides SRM (Sample Ratio Mismatch) checks and advanced statistical diagnostics that are appreciated by experienced practitioners. For D2C brands that want simple revenue-first reporting, Convert's depth can add overhead.
| Plan | CustomFit.ai | Convert.com |
|---|---|---|
| Starter | $99/mo (50K MUV) | ~$99/mo (1K sessions โ very limited) |
| Growth | $249/mo (100K MUV) | ~$599/mo (50K sessions) |
| Enterprise | Custom | Custom |
| Free trial | 14 days, no credit card | 15-day free trial |
| Agency multi-client | No | โ (agency plans available) |
Convert.com's pricing is session-based and can escalate quickly for high-traffic stores. At 50,000 monthly unique visitors, CustomFit.ai's $249/month Growth plan compares favorably to Convert's comparable traffic tier. Convert does offer agency plans with multi-project support that CustomFit.ai does not match for agency use cases.
Switching from Convert.com to CustomFit.ai is straightforward:
How does Convert.com pricing compare to CustomFit.ai at scale? Convert.com uses session-based pricing that scales with traffic. For a store with 100,000 monthly unique visitors, Convert's equivalent tier costs approximately $599/month. CustomFit.ai's Growth plan at that traffic level is $249/month. At enterprise traffic, both move to custom pricing.
Does Convert.com have a Shopify app? No. Convert.com does not have a native Shopify App Store listing. It integrates via JavaScript snippet. CustomFit.ai has a one-click Shopify app with automatic order data integration.
Is Convert.com better for agencies than CustomFit.ai? Yes, for agencies specifically. Convert.com offers multi-project management, collaborative workspaces, and agency billing structures that CustomFit.ai does not currently support. CustomFit.ai is optimized for individual brand accounts.
Does Convert.com support AI-powered traffic allocation? No. Convert.com uses traditional A/B testing with manual traffic split controls. CustomFit.ai's AI dynamically reallocates traffic toward winning variants as the test runs, which can reduce test duration by 20โ40%.
How does statistical significance methodology differ between the two? Convert.com offers both frequentist and Bayesian significance options with practitioner-controlled settings. CustomFit.ai uses frequentist significance with AI-driven traffic allocation. Convert's statistical flexibility is better for teams with strong CRO methodology expertise; CustomFit.ai's automated approach is better for marketing teams that want results without statistical overhead.
Can I use CustomFit.ai for privacy-compliant testing? Yes. CustomFit.ai is GDPR-ready, ISO 27001, and SOC 2 certified. For strongly regulated industries, Convert.com's deeper cookieless tracking options may offer more configuration flexibility.
