Best Free Shopify A/B Testing Apps (2026)

Updated June 23, 2026 · 9 min read

A/B testing is one of the highest-ROI things you can do for a Shopify store — but you should not have to pay enterprise prices just to find out whether a different product image sells better. The good news: several Shopify apps let you start testing for free. The catch: "free" means very different things from one app to the next.

This guide compares the best free and freemium Shopify A/B testing apps in 2026, explains what "free" actually means in each case, and helps you pick the right one for your store.

Transparency note: we make ABSplitLab, so we are not a neutral reviewer. We have tried to describe every app fairly and tell you exactly who each one is best for — including cases where another app is the better choice. Always verify current pricing and free-plan limits on each app's Shopify App Store listing, since these change often.

First: free plan vs. free trial

Before you install anything, understand the difference, because it determines whether you can actually keep testing for free:

• Free plan — free forever, usually capped by number of experiments or monthly visitors. Great for ongoing, low-volume testing.
• Free trial — free only for a set window (often 7–14 days), then you pay. Good for evaluating a premium tool, not for testing on a long-term budget.

Many "free" lists mix these together. We have noted which is which below where we can — but confirm on the live listing, as apps change their plans.

Quick comparison

Free-plan availability and limits change frequently. The "free offering" column is a starting point, not a guarantee — always confirm on the Shopify App Store before installing.

1. ABSplitLab — best for affordable, simple testing

ABSplitLab is built for the merchant who wants to start testing today without a big budget or a CRO background. It runs as a native Shopify 2.0 app, so there is no code to manage and no external script to maintain.

• Free plan: 1 active experiment and 1,000 visitors per month, no credit card required.
• What you can test: product images, titles, descriptions, prices, and CTA buttons.
• Performance: a snippet under 2KB with anti-flicker handling, so your Lighthouse score stays intact.
• Stats: built-in statistical significance tracking with a real-time progress indicator.

Best for: small and mid-size stores that want straightforward A/B testing at the lowest cost. Paid plans start at $19/month when you outgrow the free tier. See the full feature list and pricing.

2. Shoplift — best for full-page testing

Shoplift is known for whole-page and theme-section A/B testing through a visual editor. If your workflow centers on redesigning landing pages, home pages, or large template sections and comparing entire layouts, Shoplift is purpose-built for that. It is a strong, polished product for design-led testing teams.

Best for: stores that test full-page layouts rather than individual product elements. See our detailed ABSplitLab vs Shoplift comparison.

3. Intelligems — best for price & profit testing at scale

Intelligems is a mature, premium tool especially well known for pricing and profit experimentation — testing not just conversion rate but margin and profit per visitor. It is aimed at higher-volume and enterprise stores with dedicated growth teams. It tends to be a premium-priced tool rather than a free-plan option, so check its current terms.

Best for: larger stores running sophisticated price and profit experiments. See our ABSplitLab vs Intelligems comparison.

4. Visually.io — best for personalization + testing

Visually.io combines A/B testing with on-site personalization and merchandising. If you want to go beyond simple split tests into audience-based personalization and more advanced experiences, it offers a broader toolset. That power comes with more to learn and configure.

Best for: stores that want personalization alongside A/B testing and are comfortable with a more advanced platform.

5. Neat A/B Testing — best for simple split tests

Neat A/B Testing focuses on doing the basics cleanly: straightforward split tests without a steep learning curve. It is a reasonable option if you want minimal setup and a focused feature set. Confirm its current free-tier limits on the App Store.

Best for: merchants who want a no-frills testing experience.

6. ABConvert — best for price & shipping testing

ABConvert is known for price testing, shipping-threshold testing, and theme/template tests. If pricing and offer experiments are your priority but you want a lower-cost alternative to enterprise tools, it is worth evaluating. Check the current free-tier limits before committing.

Best for: stores focused on price and shipping experiments on a budget.

How to choose the right free app

Match the tool to what you actually want to test:

• Testing product images, titles, and prices? A focused, affordable tool like ABSplitLab covers the highest-ROI tests with the least setup.
• Redesigning whole pages? A page-level tool like Shoplift fits better.
• Optimizing margin and profit at scale? A premium tool like Intelligems is built for that.
• Want personalization too? Look at a broader platform like Visually.io.

Also weigh three practical factors: does it offer a real free plan (not just a trial), is it a native Shopify app that will not slow your store, and does it track statistical significance so you do not call winners too early? For more on that last point, read our A/B testing best practices guide.

How to run your first free test

Whichever app you choose, your first test should be simple and high-impact:

1. Pick your best-selling product. It has the most traffic, so you will reach significance fastest.
2. Test the hero image. Image tests consistently produce the biggest lifts.
3. Use a 50/50 split and let the test run until it reaches statistical significance — do not stop early.
4. Apply the winner and move on to your next test.

Frequently asked questions

Is there a truly free A/B testing app for Shopify?

Yes. Some Shopify A/B testing apps offer a genuine free plan (free forever, with usage limits) rather than only a time-limited free trial. ABSplitLab, for example, includes a free plan with one active experiment and 1,000 visitors per month. Always check whether an app advertises a free plan or just a free trial before installing.

What is the difference between a free plan and a free trial?

A free plan is free forever, usually with limits on experiments or traffic. A free trial is free only for a set period (often 7–14 days), after which you must pay to keep using the app. For ongoing testing on a budget, a free plan is more useful than a trial.

Will a free A/B testing app slow down my Shopify store?

It depends on the app. Apps built as native Shopify 2.0 Theme App Extensions with a lightweight snippet and anti-flicker handling have minimal performance impact. ABSplitLab's snippet is under 2KB and does not block rendering, so your store speed stays intact.

What should I test first with a free A/B testing app?

Start with your best-selling product and test its hero image, since image tests typically produce the largest conversion lifts and your top product has enough traffic to reach statistical significance fastest.
