Running a D2C brand on Shopify today feels like both art and science. You have your storytelling, your visuals, your brand identity, and then you have data. Real, measurable, no-nonsense data that tells you what’s actually driving conversions.
That’s where A/B Testing steps in.
And if you’re using Shoplift (formerly Shoplift A/B Testing for Shopify), you probably already understand the value of testing your store elements. Shoplift is popular for its simplicity and Shopify-native integration. But when you start scaling, when you want to personalize experiences, run faster tests, and look deeper into visitor behavior, you might start feeling a few limitations.
This is where CustomFit.ai steps in as the best Shoplift alternative for Shopify A/B Testing, a more flexible, no-code, and conversion-focused A/B Testing Platform designed for ecommerce and D2C growth.
Let’s explore why thousands of Shopify brands are moving toward deeper experimentation and how CustomFit.ai gives them that edge.
Most D2C founders eventually realize that scaling isn’t about “doing more marketing”, it’s about optimizing what already works.
You don’t always need more ads or influencers. Sometimes, all you need is a better headline, an improved checkout flow, or a product image that tells your story better.
A/B Testing gives you clarity. Instead of relying on opinions or gut feelings, it lets you make decisions based on user behavior.
A/B Testing on Shopify answers questions like:
Each of these small questions hides a massive revenue opportunity.
And platforms like CustomFit.ai make this process frictionless, so even non-developers can launch, analyze, and roll out experiments.
Shoplift is a Shopify app focused on simple, native A/B Testing. It helps merchants experiment with store content, themes, and templates, without the need for third-party integrations.
It’s easy to set up and is a great starting point for basic A/B tests. For example, you can test hero banners, product headlines, or homepage layouts directly within your Shopify theme editor.
Where Shoplift excels:
However, as your ecommerce store grows and your experiments become more complex, you may notice limitations:
In short: Shoplift helps you start testing, but it’s not built for scaling experimentation.
That’s where CustomFit.ai becomes your next logical step.
CustomFit.ai was designed for e-commerce teams that care about both conversions and experience. It’s not a generic testing tool. It’s built around the everyday challenges of D2C and Shopify stores, from cart drop-offs to checkout friction.
You can test your website, personalize your content, and optimize user journeys, all within a single A/B Testing Platform.
You don’t need to touch code or switch between themes.
CustomFit.ai’s visual editor allows you to make changes directly on your live Shopify site: text, buttons, banners, product placements, everything.
For example:
All of this can be A/B tested instantly, with no developer dependency.
One of the biggest issues with many testing tools (including some Shopify plugins) is the flicker, that split-second flash before the variant loads. It might seem small, but it impacts trust and conversions.
CustomFit.ai ensures flicker-free rendering, keeping your site speed intact and your user experience seamless.
Shoplift is good for one-size-fits-all tests. But ecommerce isn’t one-size-fits-all anymore.
CustomFit.ai lets you show different content to different audiences, based on their location, referral source, device type, or behavior.
Examples:
This personalized testing gives your store the edge to increase conversion rate ecommerce faster than any static A/B test could.
Just like Shoplift, CustomFit.ai integrates directly with Shopify. But it goes deeper, it supports product pages, collections, landing pages, and even checkout optimizations.
You can:
Shoplift shows which variant “won.” CustomFit.ai tells you why.
You can dig into user behavior, scroll depth, click rates, dwell time, and purchase journey.
For marketers, this means you can finally answer:
“What’s working, for whom, and why?”
Unlike typical Shopify apps, CustomFit.ai isn’t just plug-and-play. Their support is proactive, helping brands plan experiments, analyze results, and optimize based on insights.
Switching doesn’t mean starting over.
Here’s what migration looks like for most Shopify stores:
You’ll instantly see more flexibility in test design, richer insights, and faster execution.
A D2C footwear brand was using Shoplift to test homepage headlines. But they wanted to go deeper, test add-to-cart CTAs, banner variations, and location-specific offers.
They moved to CustomFit.ai. Within a month:
The key difference wasn’t just testing more things, it was testing smarter, faster, and with intent.
If you’re moving from Shoplift to CustomFit.ai, here are five A/B tests worth running right away:
Test two hero messages, one emotion-driven and one offer-driven.
Test image-first vs. feature-first layout.
Sometimes, leading with benefits outperforms visuals.
Change text, color, and placement.
For mobile users, sticky CTAs often lift conversions.
Test ₹999 vs ₹1,000 or “Flat ₹500 Off” vs “50% Off.”
Small changes in perception make big differences.
Test single-page vs multi-step checkout, or “Pay Now” vs “Proceed to Checkout.”
Every test you run gives you actionable insights, what to keep, what to change, and what to scale.
The biggest win of moving to an advanced A/B Testing Platform like CustomFit.ai isn’t one test or one metric; it’s a habit.
When your team gets used to testing instead of guessing, growth becomes predictable.
You stop arguing over design opinions and start talking about conversion data.
In D2C ecommerce, that’s the real competitive advantage.
