Running a D2C brand on Shopify today is not just about having good products. It’s about giving every visitor an experience that convinces them to stay, explore, and finally purchase. That’s where A/B Testing comes in—an indispensable tool for ecommerce founders who want to increase conversion rate in ecommerce.
Shopify merchants now have several options for testing platforms, and two names often come up: Intelligems and CustomFit.ai. For brands evaluating an Intelligems alternative, CustomFit.ai often stands out as one of the best alternatives a/b testing tool for Intelligems, offering more flexibility beyond pricing experiments. Both are powerful in their own right, but they differ in approach, focus, and long-term fit for growing brands.
This blog dives deep into the comparison between the two, looking at how each platform works, what they do well, where they fall short, and why CustomFit.ai could be the better choice for Shopify A/B Testing if you’re serious about scaling without adding unnecessary complexity.
Intelligems is a Shopify app designed to help merchants experiment with pricing, shipping fees, and on-site elements. Instead of just focusing on headlines or button colors, Intelligems markets itself as a profit optimization platform. Its key premise is that even small tweaks in pricing or free shipping thresholds can significantly impact margins.
Intelligems works well as a niche A/B Testing Platform for pricing and shipping, but when it comes to broader ecommerce needs, many merchants find themselves looking for more versatility. This is where many store owners start searching for the best alternative for Intelligems, something that can handle pricing tests while also supporting full website experimentation and personalization.
CustomFit.ai is a full-stack A/B Testing Platform built specifically for ecommerce, with Shopify integration at its core. Unlike tools that focus on only pricing or simple element tests, CustomFit.ai enables merchants to create, test, and personalize experiences at scale without needing developers.
Intelligems:
Built as a Shopify-native app, Intelligems makes it straightforward to run experiments on pricing, shipping thresholds, and simple page elements. Installation is quick, but the scope is narrow. If your main interest lies in testing profit-related experiments, it does the job well.
CustomFit.ai:
CustomFit.ai focuses on speed, simplicity, and accessibility for marketers. Its visual editor allows non-technical users to run experiments on Shopify without coding. From headlines to product images, setup takes minutes, not days.
Why CustomFit.ai?
If your priority is fast execution with minimal learning curve, CustomFit.ai is a better choice. It enables experimentation across product pages, landing pages, and checkout without limiting you to pricing or shipping alone.
Intelligems:
The app primarily optimises pricing and shipping rules. While useful, it lacks advanced personalisation features that modern ecommerce demands. Every visitor sees the same experience, even if they behave differently.
CustomFit.ai:
Personalisation is at the heart of CustomFit.ai. Beyond A/B Testing, it allows targeting based on location, referral source, device, or user history. This means a returning shopper can see a loyalty discount, while a new visitor might see a welcome banner.
Why CustomFit.ai?
For ecommerce brands where customer journeys differ, CustomFit.ai’s dynamic content helps increase conversion rate ecommerce by showing the right experience to the right audience. Merchants who want more than just pricing tests often view CustomFit.ai as the most practical Intelligems alternative for Shopify a/b testing.
Intelligems:
Best known for price testing (e.g., ₹999 vs ₹1,099) and shipping experiments. It’s effective for profit optimisation but doesn’t support deeper website layout or funnel testing.
CustomFit.ai:
Supports A/B testing, split URL testing, and personalisation experiments. You can ab test product descriptions, banner designs, checkout layouts, and upsell flows—all in the same platform.
Why CustomFit.ai?
If you’re looking for a well-rounded A/B Testing Platform, CustomFit.ai provides flexibility for high-impact website and funnel experiments, not just profit levers.
Intelligems:
Provides ecommerce-focused reporting around revenue per visitor and profit impact, which is excellent for pricing-driven tests. However, insights stop short when you want granular behavioural data.
CustomFit.ai:
Offers real-time analytics with an intuitive dashboard. Its AI suggests top-performing variants and provides actionable insights on user behaviour, engagement, and conversions.
Why CustomFit.ai?
For brands wanting fast, data-backed decision making, CustomFit.ai provides real-time clarity beyond just pricing numbers.
Intelligems:
Strong for blanket experiments (everyone sees variant A or B), but lacks segmented targeting capabilities.
CustomFit.ai:
Excels in segmentation. You can target experiments to specific user groups—for example, only first-time visitors from Instagram ads, or repeat customers who purchased in the last 30 days.
Why CustomFit.ai?
For ecommerce stores that thrive on tailoring experiences, segmentation drives higher conversion rates and repeat purchases.
Intelligems:
Lightweight, but limited to Shopify-native experiments. If your testing needs expand, the scope may feel restrictive.
CustomFit.ai:
Designed for flicker-free testing and fast rollouts. Experiments run smoothly without performance trade-offs, ensuring customer experience isn’t disrupted.
Why CustomFit.ai?
For fast-growing Shopify stores, CustomFit.ai offers agility—launch, test, and iterate quickly without slowing your site.
Intelligems:
Pricing is tied to usage and scale. For small stores, it costs $59/month and can feel affordable. But as you grow and run more experiments, costs increase significantly.
CustomFit.ai:
Competitive and accessible pricing, designed to support D2C brands of all sizes. You get A/B Testing and personalisation in one package without paying separately for add-ons.
Why CustomFit.ai?
For brands wanting long-term scalability without runaway costs, CustomFit.ai balances affordability with capability.
For Shopify merchants who want to increase conversion rate ecommerce, the key isn’t just testing product prices—it’s testing the entire journey. From the landing page to the checkout button, small changes can drive big improvements.
CustomFit.ai stands out because it doesn’t lock you into just one kind of experiment. You can ab test:
Unlike tools built for narrow testing, CustomFit.ai provides the flexibility to experiment, personalize, and scale. For ecommerce brands looking beyond margins into long-term customer experience optimization, it’s often the better fit.
