The best A/B testing app for Shopify in 2026 is Shoplift, which tests full themes and templates inside the Shopify Theme Editor and holds a 4.9 star rating across 134 reviews. Intelligems is the pick for price and profit testing, ABConvert is the only app on this list carrying the Built for Shopify badge, Visually has the cheapest paid entry at $15, and Trident AB has the only true free plan. All data below is pulled directly from the Shopify App Store as of November 2, 2026.

Why A/B Testing Is the Cheapest Conversion Lever You Are Not Pulling

Most Shopify stores change their product pages on instinct: a new hero image because the founder liked it, a rewritten headline because a competitor had one. A/B testing replaces that guesswork with a controlled experiment, splitting traffic between the current page and a variant and measuring which one actually converts. The gap between a category's median conversion rate and its top quartile is roughly a doubling, and the stores at the top of that range got there through iteration, not taste. The numbers by vertical are in our Shopify conversion rate benchmarks by industry.

Shopify has no built-in A/B testing for themes or product pages as of this writing, so the capability comes from apps. The five below are the ones worth your shortlist.

How We Picked These Five

We compared ratings, review counts, pricing, testing scope (theme, template, price, shipping, checkout), and statistical approach across the A/B testing category on the Shopify App Store, checking every listing on November 2, 2026. For transparency: we build Moast, a Shopify-native shoppable video UGC app. Moast does not compete in the A/B testing category, and no app on this list paid for placement; the ranking reflects the listing data and feature depth you can verify through the links in each entry.

The Top 5 at a Glance

Ratings, review counts, and prices from each app's Shopify App Store listing, November 2, 2026.

1. Shoplift: Best Overall A/B Testing App for Shopify

Shoplift holds the highest rating of the five, 4.9 stars across 134 reviews, and takes the top spot because it tests at the level where most conversion problems actually live: the theme. Instead of injecting JavaScript overlays onto your pages, Shoplift lets you build the variant in the Shopify Theme Editor itself, run a 50/50 split against the live theme, and publish the winner straight into production. That architecture is why Shoplift positions itself as a CRO platform rather than a testing widget, and the claim has weight: the company reports more than 3,500 Shopify Plus brands running CRO programs on it, with named customers including Liquid Death, Our Place, and Skullcandy.

The feature set goes well past basic splits. Results are Bayesian, reported as lift ranges with a probability of winning across conversion rate, revenue per visitor, and average order value. Audience personalization targets by device, country, UTM, referrer, and Klaviyo segment. Signals monitoring flags metrics drifting outside their normal range, and an API built for AI assistants lets you run tests from Claude or ChatGPT on the Advanced plan.

The honest trade-offs: there is no free plan, pricing scales with your site's monthly unique visitors (Core starts at $74 and lists at $99 per month, as of November 2026, per the listing), and price testing requires the Advanced plan, which starts at $299. Shoplift is the pick for stores treating testing as a program; a store wanting one cheap experiment should start lower on this list.

2. Intelligems: Best for Price and Profit Testing

Intelligems carries the largest review base in the category, 4.8 stars across 198 reviews, and it earned that base on a specific strength: testing the numbers rather than the layout. Price points, discount depths, shipping rates, and post-purchase offers can all be split tested, and because Intelligems tracks COGS alongside revenue, it reports winners by profit, not just conversion rate. A variant that converts slightly worse at a meaningfully higher margin is a win most testing tools cannot even see.

Pricing is modular, which cuts both ways: Smart Content starts at $69 per month, Smart Promotion and Smart Shipping each list at $112.10, and the Unlimited plan with every feature and a dedicated success manager runs $349, each with a 14-day trial, as of November 2026. If you want the full suite, Unlimited is the real price. Content-layout testing exists but is not the product's center of gravity, which is why Intelligems sits at two rather than one: pair it with margin questions and it is the strongest tool on this list.

3. ABConvert: The Built for Shopify Badge Holder

ABConvert is the only app of the five carrying the Built for Shopify badge, Shopify's marker for apps meeting its performance and integration standards, and that matters in a category where a badly built testing script can slow the very pages it is measuring. Rated 4.7 across 84 reviews, it covers template and theme tests, URL redirect tests, price tests, shipping and checkout tests, with pricing based on test orders rather than traffic: $99 per month covers 1,000 test orders, $199 covers 5,000, with overage per thousand beyond that, as of November 2026.

That order-based model is friendly to high-traffic stores with modest order volume, and rough on stores with high conversion counts. Other caveats worth knowing before the trial: price testing starts on the $199 Growth plan, and checkout, cart, and upsell tests require Shopify Plus. For a Plus store already paying for the platform, ABConvert's scope is hard to beat at the price.

4. Visually: Cheapest Serious Entry Point

Visually A/B Testing & CRO is rated 4.8 across 148 reviews and starts at $15 per 30 days for up to 100 orders, with a free tier for development stores, the lowest-cost paid entry on this list as of November 2026. The product bundles more than testing: an AI-assisted visual editor, personalization by segment, and upsells and cross-sells ship in the same app, so a small store gets a basic CRO stack for the price of lunch.

The trade-off is the order-based ladder: $25 covers 200 orders and $80 covers 600, so a growing store climbs tiers quickly, and at scale the economics converge with the bigger platforms above. Visually also leans on its no-flicker rendering and even advertises migration support from VWO, Intelligems, and Shoplift. For a store doing under a few hundred orders a month that wants to start testing this week, this is the value pick.

5. Trident AB: The Free Starting Line

Trident AB is the only app here with a genuinely free plan: up to 500 impressions per month and a single running test, no card required, as of November 2026. Paid tiers are the cheapest in the category too, from $19.99 to $49.99 per month. Rated 4.7 across 49 reviews, it handles the fundamentals: product page tests, pricing tests, copy and image variants, with purchase tracking and funnel analytics.

The limits are what you would expect at the price: the smallest review base on this list, a 5-day trial on paid plans rather than 14, and none of the theme-level architecture, profit accounting, or personalization of the apps above. That is fine. Trident's job is to let a small store run its first controlled experiment for free, learn whether testing changes decisions, and graduate upward with evidence in hand.

How to Choose: Match the App to the Question You Are Asking

The right pick depends on what you are actually trying to learn. If the question is "which page layout converts better", Shoplift's theme-level testing answers it most cleanly. If it is "what should this product cost", that is Intelligems, because profit-aware price testing is its native language. If it is "can we test without slowing the site", ABConvert's badge is the signal. And if the question is "is A/B testing even for us", Visually at $15 or Trident free answers it with almost no downside. Whichever you install, give each test enough traffic to reach significance before calling it; the apps' own calculators will tell you, and impatience is the most common way stores turn a good tool into random noise.

What to Test First: The Highest-Leverage Product Page Experiments

A testing app is only as useful as its backlog, so seed it with experiments that move revenue rather than shades of blue. The classics earn their place: headline framing, hero image, above-the-fold social proof, shipping threshold messaging. Our list of top Shopify apps for conversion rates covers the broader stack those tests sit inside.

One experiment consistently worth the slot: customer video on the product page. Across the 6,080 Shopify stores on the Moast network, shoppers tap play on 21.1% of the occasions a video widget is shown, and tagged video drives roughly $1,286 in influenced and direct revenue per 1,000 views, per our 25 video commerce statistics. That is exactly the kind of change an A/B test settles for your store specifically: run the page with and without shoppable video and let the revenue data decide, the method laid out in does shoppable video increase conversion and how to increase Shopify conversion rate with video. If the test wins, the follow-up playbook is in increasing Shopify PDP revenue.

Frequently Asked Questions

What is the best A/B testing app for Shopify?
Shoplift is the best A/B testing app for Shopify in 2026 for most stores, rated 4.9 stars across 134 reviews as of November 2, 2026. It tests full themes and templates inside the Shopify Theme Editor, reports Bayesian results across conversion rate, revenue per visitor, and average order value, and publishes winners directly to the live theme. Intelligems is the stronger pick if price and profit testing is the priority.

What is the best free A/B testing app for Shopify?
Trident AB has the only true free plan among the leading options: up to 500 impressions per month and one running test at no cost, as of November 2026. Visually is the cheapest paid entry at $15 per 30 days for up to 100 orders. The larger platforms, Shoplift, Intelligems, and ABConvert, offer 14-day trials but no free tier.

How much do Shopify A/B testing apps cost?
From free to roughly $1,000 per month, as of November 2026. Trident AB starts free, Visually at $15, Intelligems at $69, Shoplift from $74, and ABConvert at $99. Full-featured tiers run $349 (Intelligems Unlimited) to $999 (Shoplift Pro with a dedicated CRO manager). Most price by traffic or test orders, so cost scales with store size.

Can you A/B test prices on Shopify?
Yes, with the right app. Intelligems is built around price testing and reports results by profit using your COGS data. Shoplift offers price testing on its Advanced plan, and ABConvert from its $199 Growth plan. Test pricing carefully across markets, and show each returning visitor a consistent price during the test window, which these apps handle automatically.

Does Shopify have built-in A/B testing?
No. As of November 2026, Shopify does not include native A/B testing for themes, product pages, or prices on standard plans, which is why the category exists as apps. Shopify's own analytics can compare performance over time, but that is before-and-after observation, not a controlled split test with randomized traffic.

How long should I run an A/B test on my Shopify store?
Until the test reaches statistical significance, which for most stores means at least two full weeks and often longer on lower traffic. Two weeks captures both weekday and weekend behavior twice. Ending a test the moment one variant pulls ahead is the most common testing mistake; the leading apps report a probability of winning so you can hold out for a confident call.
