The 8 best Shopify A/B testing apps in 2026 (one of them is ours)

The best Shopify A/B testing app depends on what you want to test. The 2026 short version: Shopify Rollouts for free theme splits if you are on the Grow plan, Intelligems for price tests, Shoplift for theme tests with real statistics, Convert for a full experimentation engine, and ABConvert or Trident AB when the budget is tight.

One thing before the list. We build one of these eight apps. StorePilot sits last, inside a disclosure box, with no ratings and no reviews, because it has not launched yet. Every other number here was pulled from the vendor's pricing page or App Store listing on July 3, 2026; anything we could not verify says "pricing changes, verify live" instead. Roundups in this category tend to be written by whoever ranks their own tool first. The least we can do is put ours last and show our work.

How this list was put together

No affiliate links, no sponsored placements, no star ratings copied from a 2023 roundup. Every price quoted below is what the vendor's own page said on July 3, 2026.

Ratings appear only where a real App Store listing shows them, with the review count next to the score. Each entry gets the same treatment: one-sentence definition, who it fits, verified cost, and the trade-off the homepage omits.

This is a tool ranking, not a how-to. The mechanics of running a test well, sample size, significance, revenue per visitor, live in the full Shopify A/B testing guide.

1. Shopify Rollouts: the free, native one

Shopify Rollouts is Shopify's built-in A/B testing feature: it splits live traffic between theme versions on Shopify's own servers, with no app to install and no add-on fee.

It became generally available with the Spring '26 Edition (June 17, 2026) and lives under Markets > Rollouts in the admin. Because the split happens server-side, before the page is sent, there is no flicker and no speed penalty, a real edge over every script-based tool here.

Two catches, both documented by Shopify's Help Center. First, the plan gate: scheduling theme changes works on Basic and up, but the actual traffic-split experiment needs the Grow plan or higher, about $105 a month in the US on monthly billing, verify live. Second, the missing verdict: the analytics show conversion rate, average order value, gross sales and sessions, but no significance test, no winner call, and no revenue per visitor. It also cannot test prices or discounts, and the unit of a test is a whole theme version, not one section. We took it apart line by line in the full Rollouts teardown.

Best for: theme tests at zero extra cost on Grow or higher. Pricing: free add-on; the experiment needs the Grow plan. Watch out: no statistics engine, so you decide when a result is real.

2. Intelligems: the price-testing specialist

Intelligems is the deepest price-testing app on Shopify: it tests prices, shipping rates, offers and bundles, and scores the results on profit rather than clicks.

Every other tool here mostly rearranges the page. Intelligems experiments with the money itself, the test category most likely to move margin and the one Rollouts cannot touch. Its profit-per-visitor scoring, using your actual costs, is the right yardstick for a price test.

Pricing, verified on intelligems.io July 3, 2026: Core is $79 a month ($59 on annual billing) and covers content and landing-page tests. The thing Intelligems is famous for, price testing, unlocks on the Plus tier at $499 a month ($374 annual). Blue, at $999 ($749 annual), adds subscription and multi-currency price tests. A redirect-only plan starts at $49 for stores under 3,000 monthly orders. The other honest note: price tests read on orders, not sessions, so a low-order store waits a long time for a significant result no matter what it pays.

If the $499 gate is the sticking point, we compared the honest Intelligems alternatives, including cheaper ways to run a price test.

Best for: price, shipping and offer tests at real order volume. Pricing: $79/mo entry; price testing at $499/mo ($374 annual). Watch out: the tier you probably want it for is the expensive one.

3. Shoplift: the theme tester with a stats engine

Shoplift is the theme-testing pick: template, section and whole-theme tests with a Bayesian significance engine, holding a 4.9-star average across 128 App Store reviews as of July 2026.

Where Rollouts splits a whole theme version and hands you raw numbers, Shoplift tests at the section and template level and tells you when a result is significant. Its Lift Assist feature builds pattern-based section variants for you, shortening the distance from hypothesis to live test. Audience targeting arrives on higher tiers.

Pricing, verified on the App Store listing July 3, 2026: Core is $99 a month (from $74 on annual billing, metered by monthly unique visitors), Advanced is $399 (from $299) and adds price testing plus deeper segmentation, Pro is $999 (from $699). All tiers carry a 14-day free trial.

Trade-offs: it runs head-to-head A/B tests rather than multivariate, and the visitor-metered bill climbs as your store grows. It also stops at the storefront; shipping and checkout experiments are not its ground.

Best for: theme and section tests with a real significance verdict. Pricing: from $99/mo ($74 annual), visitor-metered. Watch out: costs scale with traffic, and tests are A/B only, no multivariate.

4. Convert: the full stats engine

Convert Experiences is a standalone experimentation platform rather than a Shopify App Store app: A/B, multivariate and multi-page testing with a statistics engine agencies have trusted for over a decade.

This is the tool for a store, or more often an agency, running a genuine testing program: many experiments, custom goals, integrations across more than one property. The Growth plan covers 100,000 tested users a month, which is more headroom than most Shopify stores will ever use.

Pricing, verified on convert.com July 3, 2026: Growth at $399 a month ($299 on annual billing), Pro at $599 ($420 annual), enterprise on request, 15-day free trial.

Trade-offs: it runs client-side, so it manages flicker with anti-flicker masking rather than a server-side split, and it brings no hypotheses. You supply the ideas, the variants and usually some developer time. If nobody ships an experiment most months, you are paying $299 for an engine that idles.

Best for: stores and agencies running experiments monthly. Pricing: from $299/mo on annual billing. Watch out: client-side delivery, and you bring every hypothesis.

5. ABConvert: money tests, metered by orders

ABConvert is a Shopify A/B testing app that covers price, shipping rate, theme, page and checkout tests, priced by the number of test orders you run.

Think of it as the mid-market answer to Intelligems: shipping tests from $99 a month and price tests from $199, instead of $499. It holds a 4.7-star average across 76 App Store reviews as of July 2026, and the breadth runs from URL redirect tests to shipping-rate experiments.

Pricing, verified on the App Store listing July 3, 2026: Starter at $99 a month includes 1,000 test orders (then $59 per extra thousand), Growth at $199 includes 5,000, Scale at $399 includes 15,000, Pro at $599 includes 30,000. One gate to know about: Starter covers shipping, theme, page and checkout tests, but price testing starts on Growth. Every tier has a 14-day trial.

Trade-offs: order-metered pricing means a good month costs more, so model the bill at your real volume before committing. And its checkout tests reach only as deep as Shopify allows on your plan; meaningful checkout customization is still Plus territory.

Best for: price and shipping tests without the enterprise bill. Pricing: from $99/mo plus order-based overage; price tests from $199/mo. Watch out: the meter runs on orders, so success raises the bill.

6. Trident AB: the budget starter

Trident AB is the cheapest way to run a first A/B test on Shopify: product, price and page tests from free to $49.99 a month, metered by impressions.

The free plan gives you one test and 500 impressions a month. Here is the honest read on that cap: 500 impressions decides nothing. Use the free plan to learn the workflow, not to make decisions. Paid tiers, verified on the App Store listing July 3, 2026: Premium at $19.99 a month (5,000 impressions), Business at $24.99 (50,000), Enterprise at $49.99 (unlimited), each with a 5-day trial. The listing shows 4.2 stars across 29 reviews as of July 2026, a thinner track record than Shoplift or ABConvert.

Trade-offs: analytics are basic next to the engines above, and the impression caps on the cheap tiers starve tests of the volume significance needs. Fine as a $20 habit for poking at headlines and images; the wrong tool for a revenue program.

Best for: a first cheap test to learn the mechanics. Pricing: free plan; paid from $19.99/mo. Watch out: impression caps quietly stop most tests from ever reaching significance.

7. Varify.io: flat rate, unlimited traffic

Varify.io is a German testing platform that connects to Shopify through a small script instead of an app, and charges one flat rate with no traffic meter.

The pitch is the missing meter. Shoplift and ABConvert both get more expensive as you grow; Varify's Growth plan is €199 a month (€149 on annual billing) whether you test ten thousand visitors or a million, verified on varify.io July 3, 2026. Pro is €349 (€249 annual). A visual editor builds variants without code, it works on any Shopify plan, and there is a free trial with no card required.

Trade-offs: it is a client-side snippet, so anti-flicker masking again rather than a server-side split. Billing is in euros. The Growth plan caps you at 5 active experiments and 1 domain. And with no App Store listing, there are no reviews to weigh, which cuts both ways.

Best for: high-traffic stores tired of visitor-metered pricing. Pricing: flat €199/mo (€149 annual). Watch out: script-based delivery and a 5-experiment cap on the entry plan.

8. StorePilot: ours, and not launched yet

StorePilot is an AI CRO agent for Shopify, currently in pre-launch waitlist: it watches real shopper behavior, finds the friction, builds the test variant, and lets deterministic statistics judge the result on revenue per visitor.

Every splitter on this list assumes you arrive with a hypothesis and a built variant. StorePilot starts earlier. It ranks what is losing you money, generates the fix as a reversible, theme-safe change you preview before anything ships, and runs the test honestly: minimum traffic thresholds, no early winner calls, calibrated confidence. On thin traffic it swaps the split for an apply-and-measure method with holdbacks, because most stores cannot feed a split enough visitors to reach a verdict. One design choice matters more than the rest: the AI proposes, but fixed statistical rules decide the winner, an argument we make in full in Never let an AI decide your A/B test.

What it will not do: price tests, discount logic, or checkout rebuilds, the same platform limits everyone above hits. Scope at launch is the product page and cart. Pricing: free for the first three months for waitlist founders, then a founding rate (anchor $129 a month; the live number is on the pricing page).

Best for: stores that want the friction found, the variant built, and the verdict honest, at any traffic level. Pricing: waitlist; free first 3 months, then ~$129/mo founding rate. Watch out: pre-launch. Judge it when it ships.

RPV is revenue per visitor. App Store ratings as of July 2026: Shoplift 4.9 (128 reviews), ABConvert 4.7 (76), Trident AB 4.2 (29). Rollouts is native, and Convert and Varify are not App Store apps, so they have no listing rating.

The verdict, by use case

Pick by the job in front of you, not by the star rating. Five situations cover almost every store.

That last case covers more stores than any vendor admits. Detecting a typical small lift takes tens of thousands of visitors per variant, so a store doing three thousand sessions a month can run a split for a year and learn nothing. The sequential path, apply one change, measure against baseline, keep or revert, is slower per decision but actually reaches decisions. That method is the core of what we are building with StorePilot, and the wider playbook is in our CRO guide for Shopify.

Eight tools, one rule: buy the app that matches the test you actually need to run next, and trust nothing, ours included, that will not show you its math.

Questions merchants keep asking

What is the best free A/B testing app for Shopify?

Shopify Rollouts, if you are on the Grow plan or higher. It is native, server-side, and carries no add-on fee, though it gives you raw metrics with no significance verdict. On Basic, Trident AB's free plan lets you try the workflow, but its 500-impression monthly cap cannot reach a trustworthy result.

Does Shopify have built-in A/B testing?

Yes. It is called Rollouts, generally available since the Spring '26 Edition (June 17, 2026). It splits live traffic between theme versions under Markets > Rollouts, server-side, with no flicker. The experiment is gated to the Grow plan or higher, and it reports performance metrics without a statistical verdict (Shopify Help Center). Full teardown: our Rollouts guide.

Can I A/B test prices on Shopify?

Yes, but not with Rollouts, which cannot touch prices or discounts. Intelligems is the deepest option, with price testing unlocking on its $499/mo Plus tier. ABConvert runs price tests from its $199/mo Growth tier, and Shoplift's Advanced tier ($399/mo) added price testing. All prices verified July 2026; they change, so check live. More options: the Intelligems alternatives.

How much do Shopify A/B testing apps cost?

From $0 to about $999 a month, as of July 2026. Rollouts is free with a Grow plan gate. Trident AB runs free to $49.99. The serious tools cluster between $79 and $499: Shoplift from $99, ABConvert from $99, Convert from $299 on annual billing, and Intelligems price testing at $499.

Which A/B testing app is best for a low-traffic Shopify store?

Honestly, none of the split-testing apps. Detecting a small lift takes tens of thousands of visitors per variant, so a store doing a few thousand sessions a month cannot feed a split test. Sequential methods, where you apply one change and measure against a baseline, fit better. That is the approach StorePilot (ours, pre-launch) is built on.

Do A/B testing apps slow down my Shopify store?

Server-side tools do not: Rollouts assigns the version before the page is sent, so nothing swaps after load. Script-based tools such as Convert and Varify run client-side and manage flicker with anti-flicker masking, which can add a short delay. Before buying, ask the vendor one question: where does the split happen?

Can I A/B test my Shopify checkout?

Barely, unless you are on Shopify Plus. Rollouts can test checkout configurations on Grow or higher, and ABConvert lists checkout tests, but meaningful checkout customization runs through Checkout Extensibility, a Plus feature. For most stores the testable ground is the product page and cart, which every app here can reach.
