Best Shopify A/B Testing Apps 2026: 10 Ranked, $0 to $999

The best Shopify A/B testing app depends on the test you need to run. For theme tests at no extra cost, use Shopify Rollouts if you are on the Grow plan or higher; for theme and section tests with a real significance verdict, Shoplift from $99. For price tests, Intelligems at $349 a month if you have the order volume, or Elevate at $99 if you do not.

Across the ten tools below, App Store prices run from $0 to $999 a month, and every cell in the table was re-read on September 6, 2026. Most roundups for this search are written by a vendor that ranks itself first, and the AI answer at the top of Google names five tools without a single price or rating. This page does the boring part: entry price, the tier that unlocks price testing, native app or browser script, and the live App Store rating with its review count, all read the same day. Where two pages from one vendor disagree, both numbers are printed.

#	App	Entry price	Price testing from	Native or script	App Store rating	Best for
1	Shopify Rollouts	$0 add-on; experiments need the Grow plan	Not offered	Native, server-side	Built into admin, no listing	Whole-theme splits at no extra cost
2	Shopify SimGym	Free to install, charged per simulation run	Not offered	Native, simulated shoppers, no live traffic	2.8 (37 reviews)	A rehearsal before a live test
3	Intelligems	$69/mo	$349/mo Unlimited	Native app	4.8 (190)	Price, shipping and offer tests at volume
4	Shoplift	$99/mo ($74 annual)	Advanced: $399 on the App Store, $299 on shoplift.ai	Native app	4.9 (135)	Theme and template tests with a Bayesian verdict
5	Elevate	$49/mo	$99/mo Standard	Native app	4.9 (140)	The cheapest credible price test
6	ABConvert	$99/mo, order-metered	$199/mo Growth	Native app	4.6 (83)	Price and shipping tests on a mid budget
7	Visually	$15/mo (up to 100 orders)	Paid tiers, per the listing	Native app	4.8 (144)	Small stores wanting unlimited tests cheaply
8	Trident AB	Free (500 impressions); paid from $19.99	Every plan	Native app	4.6 (39)	A first cheap test to learn the mechanics
9	Convert Experiences	$299/mo annual, $399 monthly	All plans list Shopify price testing	Script	No listing	Agencies and full testing programs
10	Varify.io	€199/mo annual, €249 monthly	Not listed	Script	No listing	High traffic on a flat rate

Ratings are the App Store figure on September 6, 2026. Rollouts is a feature of the admin, not a listing. Convert and Varify are not on the App Store, so they have no rating there. Prices move; check the live page before you pay.

How the ranking works

Ten tools, ranked by how many Shopify stores they are the right answer for, from the two Shopify builds down to the two script platforms. No affiliate links, no sponsored slots, no ratings copied from an older roundup.

Every number below was read on September 6, 2026 from the app's Shopify App Store listing or the vendor's own pricing page, and each section says which. Ratings come only from the App Store; where a tool has no listing, the cell says so rather than borrowing a score from a review site. If a figure could not be read from a live page that day, it is not here.

The ranking rewards two things: how many Shopify stores a tool actually serves, which is why the free native option sits at the top without a statistics engine, and whether it can reach the tests that move margin, price and shipping, without a bill only a Plus store can carry. Rating and review count are reported but do not drive the order. Elevate and Shoplift are both 4.9 and sit fourth and fifth because they are useful to fewer stores than the tools above them.

This is a 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. And if your shortlist is already down to two, the head-to-heads are more useful than this page: Shoplift vs Intelligems covers the two most-installed native apps.

1. Shopify Rollouts: free, native, no verdict

Rollouts is Shopify's built-in experiment feature. It lives under Markets in the admin, splits live traffic between a treatment and a control on Shopify's own servers, and reports twelve metrics without calling a winner.

Shopify announced it on the changelog on March 31, 2026 as a way to save theme changes, schedule them, and run an A/B test against the current theme with real traffic. The Help Center draws the plan line clearly (requirements page, read September 6, 2026): "Rollouts are available on the Basic plan or higher" and "Experiments are available to stores on the Grow plan or higher." So a Basic store can schedule a launch, but the traffic split that makes this an A/B testing tool starts at Grow.

What a rollout can contain, per the rollout-types page: edit or replace your main theme, replace your checkout and accounts configuration, and translated theme content. What it cannot: "You can't change Liquid templates as part of a rollout," vintage themes are excluded, and "Rollouts support only online store checkouts." Prices and discounts do not appear on the list of supported changes at all, the single biggest gap between Rollouts and every paid app below.

The analytics page lists twelve metrics, from gross sales and average order value through sessions, bounce rate, add to cart rate and checkout conversion rate. What it does not mention anywhere is statistical significance, confidence, or a recommended winner. It also warns that "You can't customize the available metrics for your rollout" and that launches and experiments use "a slightly different algorithm." You are the statistics engine, which is workable if you know what a sample size is and dangerous if you do not.

The upside is the reason this sits first: the split happens before the page is sent, so there is no flicker, no extra script, and no bill. We took it apart line by line in the full Rollouts teardown.

Best for: whole-theme or checkout-configuration splits at zero extra cost on Grow or higher. Pricing: free add-on; experiments need the Grow plan (Shopify Help Center). Skip it if: you need to test a price, a discount, a single section, or you want the tool to tell you when the result is real.

2. Shopify SimGym: a rehearsal, not a test

SimGym is a Shopify-built app in AI Research Preview that sends simulated AI shoppers through your storefront and reports which of two themes they added to cart more often. No real visitor sees either version.

It is on this list because merchants search for it alongside A/B testing apps and because it is the second first-party option, but it is a different kind of tool. The Help Center describes it as an app that "uses AI-powered shoppers to simulate buyer behavior on your online store," with two modes: analyze one theme, or compare your active theme against a draft to see "which theme has a better add-to-cart ratio among the AI shoppers." The output is add-to-cart rates, summaries of the shopping experience, strengths, improvement areas and prioritized recommendations, plus individual shopper recordings.

Cost, from the Help Center on September 6, 2026: one credit per theme analysis, two per comparison, and credits are not purchasable during the research preview, though merchants may receive free allocations. The App Store listing (developer: Shopify, launched December 8, 2025) reads "Free to install. Additional charges may apply." It needs a Liquid storefront with Shopify Network Intelligence activated, and two themes for a comparison. The March 11, 2026 changelog post opened it to all eligible merchants with no waitlist.

Two honest notes. The listing carries 2.8 stars across 37 reviews, the lowest on this page by a distance. And Shopify's own documentation says results "might differ from actual buyer behavior." Use it to catch an obvious problem before you spend two weeks of live traffic on a Rollouts experiment, never to decide on its own. We checked how well its simulated shoppers track real ones in the SimGym review.

Best for: a pre-flight check on a theme change before a live test. Pricing: free to install, one credit per analysis, two per comparison, credits not for sale during the preview (Shopify Help Center). Skip it if: you want a decision. It produces a hypothesis, and its own docs say so.

3. Intelligems: the price-testing specialist

Intelligems is the deepest price-testing app on Shopify: prices, shipping rates, discounts, bundles and content, scored on profit per visitor rather than clicks. 4.8 stars across 190 App Store reviews on September 6, 2026.

Every other native app on this list mostly rearranges the page. Intelligems experiments with the money, which is the 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, and the listing now advertises Slack, Claude and ChatGPT connections plus AI-assisted content edits on every tier.

Pricing, read from the App Store listing on September 6, 2026: Smart Content at $69 a month (or $660 a year) covers landing-page, theme and content tests. Smart Merchandise and Smart Shipping are $112.10 a month each ($1,071.60 a year) for discount, bundle, upsell and shipping tests. The tier the app is famous for, Smart Pricing, arrives only on Unlimited at $349 a month, or $3,468 a year, which the listing labels a 17 percent saving. Every tier lists a 14-day free trial.

Now the second ladder. On intelligems.io/pricing the same day, Unlimited reads $2,894 a month, or $1,279 a month on annual billing with a three-month minimum, for stores up to 200,000 orders. The configurator defaults to "Up to 10,000 orders per month," and a "Limited (Tier 1)" option includes one price test a month. The per-module prices on that page render only in the browser and could not be read for this article, so they are not quoted. The point stands: $349 on the App Store and $2,894 on the vendor site are the same tier name at very different order volumes. We reconciled the two in the Intelligems pricing breakdown.

Price tests read on orders, not sessions, so a store doing 300 orders a month will wait a long time for a significant result no matter what it pays. If the $349 gate is the problem, the Intelligems alternatives cover cheaper ways to run a price test.

Best for: price, shipping and offer tests at real order volume. Pricing: $69/mo entry; price testing at $349/mo on the App Store; $2,894/mo ($1,279 annual) at 200,000 orders on intelligems.io. Skip it if: you do fewer than a few hundred orders a month, or you only want to test layouts.

4. Shoplift: the theme tester with a verdict

Shoplift tests templates, whole themes and URLs with a Bayesian predictive engine and a one-click "apply winner." It holds 4.9 stars across 135 App Store reviews as of September 6, 2026, tied for the best rating on this page.

Where Rollouts splits a whole theme version and hands you raw numbers, Shoplift tests at the template level and tells you when a result is significant. Lift Assist builds section variants from patterns, audience and country segmentation arrive on Advanced, and there is a JavaScript API for custom setups. Every tier has a 14-day trial.

Read the pricing carefully, because Shoplift's two pages disagree. The App Store listing on September 6, 2026: Core $99 a month or $888 a year ($74 a month), Advanced $399 a month or $3,588 a year, Pro $999 a month or $8,388 a year. Price testing sits on Advanced, marked "(beta)". The same day, shoplift.ai/pricing showed Core at $99 for up to 50,000 monthly visitors, Advanced at $299 for up to 100,000, and Pro at $699 a month for up to 250,000, annual billing only. So Advanced is $399 on one page and $299 on the other. Confirm which ladder you are on at checkout, and note the visitor cap either way: the bill climbs as the store grows.

Trade-offs: A/B only, no multivariate; it stops at the storefront, so shipping and checkout experiments are not its ground; and price testing is still beta on the listing. If those rule it out, the Shoplift alternatives cover the other theme testers.

Best for: theme and template tests with a real significance verdict. Pricing: from $99/mo ($74 annual); price testing on Advanced, $399 on the App Store or $299 on shoplift.ai. Skip it if: your main question is a price, or your traffic is well past the 100,000-visitor Advanced cap and you would rather pay a flat rate.

5. Elevate: the cheapest credible price test

Elevate A/B Testing Price Test is the app most roundups leave out and merchants keep finding anyway: 4.9 stars across 140 App Store reviews, a Bayesian statistics model, and price testing from $99 a month.

It has been on the App Store since December 22, 2020, older than Intelligems' listing, and its review count is now level with Shoplift's. The listing on September 6, 2026 shows three tiers, all with a 14-day trial. Basic at $49 a month, or $353 a year at a 40 percent discount, covers template, theme, split-URL and visual-editor tests. Standard at $99 a month, or $713 a year, adds price testing, shipping testing, product image testing, checkout flow testing, custom CSS and JavaScript tests and AI-generated test suggestions. Premium at $499 a month, or $3,593 a year, adds an account manager, a testing roadmap, multi-currency price testing and subscription price testing.

Read that middle tier again. Price plus shipping testing at $99 is the lowest entry on this page for a tool with a real review base, half of ABConvert's $199 gate and well under Intelligems' $349.

What the listing does not show is a visitor or order meter: no bill shock as you grow, but no published cap to check against either. Ask before you commit if you run serious volume, and put more weight on the trial than on the star rating.

Best for: stores that want to test a price without the Intelligems bill. Pricing: $49/mo entry; price and shipping tests from $99/mo (App Store listing). Skip it if: you need profit-per-visitor scoring with cost data, or a dedicated team behind the tool.

6. ABConvert: money tests metered by orders

ABConvert covers price, shipping-rate, theme, page, offer and checkout tests, priced by the number of test orders you run. 4.6 stars across 83 App Store reviews as of September 6, 2026.

Think of it as the mid-market answer to Intelligems: shipping tests from $99 a month, price tests from $199, with a visual editor and URL-redirect tests thrown in. The listing (launched October 31, 2022) shows four tiers, each with a 14-day trial: Starter at $99 a month includes 1,000 test orders, then $59 per extra thousand; Growth at $199 includes 5,000 and adds price testing, at $39 per extra thousand; Scale at $399 includes 15,000, adds multi-market price tests and monthly test reviews, at $29 per thousand; Pro at $599 includes 30,000 with a dedicated account manager, at $24 per thousand. On abconvert.io/pricing the same day, annual billing brings those to $74, $149, $299 and $449 a month, described as two months free.

One discrepancy: ABConvert's homepage says "4.8 on Shopify App Store," while the listing itself read 4.6 the day this was written. A reminder to read the listing rather than the vendor's summary of it.

Trade-offs: order-metered pricing means a good month costs more, so model the bill at your real volume. 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, at predictable order volume. Pricing: from $99/mo plus order overage; price tests from $199/mo (App Store listing). Skip it if: your order volume swings hard month to month, or Elevate's $99 already covers your test.

7. Visually: unlimited tests, order-metered, from $15

Visually A/B Testing and CRO is the app Google's AI answer keeps recommending for no-code testing, and its listing backs the pitch up: 4.8 stars across 144 reviews, an AI-powered visual editor, and unlimited A/B tests from $15 a month.

The meter is orders, and it starts very low. From the App Store listing on September 6, 2026: free for development stores; $15 a month up to 100 orders; $25 up to 200; $80 up to 600. Every paid tier lists the same features, the visual editor, personalization, unlimited upsells and post-purchase offers, and unlimited A/B tests, each with a 14-day trial. The listing has been live since June 15, 2022.

The listing's tagline advertises A/B testing of price, offer, theme and upsell, which is why it appears in the price-testing column above. The visible ladder stops at 600 orders a month, so a larger store should expect a conversation rather than a price. And it is as much a personalization and upsell tool as a testing tool; if you only want a clean split-test engine, some of what you pay for will sit idle.

Best for: small stores that want unlimited tests and a visual editor for less than the cost of a theme. Pricing: $15/mo up to 100 orders, $80/mo up to 600 (App Store listing). Skip it if: you do thousands of orders a month and need a published price, or you want statistics you can audit rather than a visual editor.

8. Trident AB: the budget starter

Trident AB, listed on the App Store as "A/B: Product and Price Testing," is the cheapest way to run a first test on Shopify: a permanent free plan, then $19.99 to $49.99 a month, metered by impressions. 4.6 stars across 39 reviews as of September 6, 2026.

The free plan gives you one test and 500 impressions a month, and 500 impressions decides nothing; use it to learn the workflow. Paid tiers, from the listing: Premium at $19.99 a month or $191.88 a year with 5,000 impressions; Business at $24.99 or $239.88 a year with 50,000; Enterprise at $49.99 or $479.88 a year, unlimited. Each carries a 5-day trial and unlocks unlimited simultaneous tests. Price testing is core to the app on every plan, which is why its listing ranks fourth in Google for this exact search.

Thirty-nine reviews over five years is a thin track record next to the tools above, analytics are basic, and the impression caps on the cheap tiers starve tests of the volume significance needs. Fine as a $20 habit for poking at product titles 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 (App Store listing). Skip it if: you intend to act on the result. The impression caps stop most tests from reaching a decision.

9. Convert Experiences: the full stats engine

Convert Experiences is a standalone experimentation platform rather than an App Store app: A/B, multivariate and multi-page testing with an engine agencies have run for over a decade, and, per its own pricing page, Shopify price testing on every plan.

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

Pricing, from convert.com/pricing on September 6, 2026: Growth at $399 a month, or $3,588 a year, which is $299 a month; Pro at $599 a month or $5,040 a year, which is $420 a month; Enterprise on request at over a million tested users. Fifteen-day trial, no card required, and the page's own summary line reads "Plans Start @ $299 Per Month (Paid Annually) or $399 Per Month (Paid Monthly)."

Trade-offs: it runs client-side, so it manages flicker with 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. It is not in the App Store's A/B testing collection, so there is no listing rating to weigh.

Best for: stores and agencies running experiments monthly across more than one property. Pricing: from $299/mo on annual billing, $399 monthly (convert.com). Skip it if: you run one test a quarter, or you want the split to happen before the page loads.

10. Varify.io: flat rate, unlimited traffic

Varify.io is a German testing platform that connects to Shopify through a script and a GA4 custom pixel 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 does not. From varify.io/en/plans/ on September 6, 2026: Growth at 249 euros a month, or 199 on annual billing (2,388 a year), with unlimited traffic, five active experiments and one website. Pro at 349 euros, or 249 on annual billing, with unlimited experiments. Enterprise from 499 euros. Every plan has a 30-day free trial with no card. Shopify connects through a Google Analytics 4 custom pixel; there is no App Store listing.

A small consistency note: Varify's homepage the same day said "For just €119 per month" in one section and "starting at €199/month" in another. The plans page is the one to trust.

Trade-offs: it is a client-side snippet, so anti-flicker masking again. Billing is in euros. Five active experiments on the entry plan is a real cap for a busy program. And with no App Store presence, there are no reviews to weigh, which cuts both ways.

Best for: high-traffic stores tired of visitor-metered pricing. Pricing: flat €199/mo on annual billing, €249 monthly (varify.io). Skip it if: you want a native app, a price test, or more than five experiments live at once on the entry plan.

Not on the list, and why

A few names come up in every search for this term and are missing above. Each has a reason.

• VWO. The App Store listing "VWO (Wingify)" is free to install, requires a VWO subscription, and had zero reviews on September 6, 2026. vwo.com/pricing and vwo.com/plans/ showed plan names but no number, and a tool with no public price cannot fill a price column. It lives in the VWO pricing investigation and the VWO alternatives for Shopify instead.
• Optimizely. Enterprise, quote-only, and rarely the right size for a Shopify store below Plus. The Shopify-sized options are in the Optimizely alternatives.
• Neat A/B Testing. On September 6, 2026, neatab.com did not resolve at all, and the app is absent from the App Store's A/B testing collection. Former users have a dedicated alternatives guide.
• Personizely, AB Tasty, Kameleoon, CustomFit. All in the App Store collection. Personizely (5.0, 90 reviews) is a popup and personalization tool with testing attached; AB Tasty (4.9, 5 reviews) and Kameleoon (unrated) are enterprise suites sold through demos; CustomFit (5.0, 20 reviews) is too new to rank on a track record.
• Split, A/B Testing Price Test. 2.9 stars across 17 reviews on the collection page. That rating is the reason.

The verdict, by use case

Pick by the test in front of you, not by the star rating. Six 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. Run your numbers in the significance calculator before you pay for anything above. If the test cannot conclude in a window you can live with, apply one change, measure against baseline, keep or revert. The wider playbook is in our CRO guide for Shopify, and the full cost picture at real traffic and order volume is in Shopify A/B testing pricing.

Disclosure: we build StorePilot, a CRO tool for Shopify that is not on the App Store and is not ranked above. Nothing on this page links to it except the box at the bottom.

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

Questions merchants keep asking

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

It splits by job. For theme and template tests with a statistical verdict, Shoplift (4.9 stars, 135 reviews, from $99 a month on its App Store listing, September 6, 2026). For price and shipping tests at real order volume, Intelligems (4.8 stars, 190 reviews, price testing on its $349 Unlimited tier). For the cheapest credible price test, Elevate's $99 Standard plan (4.9 stars, 140 reviews). For a whole-theme split at no extra cost, Shopify Rollouts on the Grow plan or higher.

Does Shopify have a built-in A/B testing tool?

Yes, two. Rollouts lives under Markets in the admin and compares a treatment against a control on live traffic. Shopify's Help Center says rollouts are available on the Basic plan or higher and experiments on the Grow plan or higher, and its analytics page lists twelve metrics with no mention of statistical significance or a winner. SimGym is a separate Shopify app in AI Research Preview that runs simulated AI shoppers through your theme instead of real traffic.

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

Shopify Rollouts, if you are on Grow or higher: no add-on fee, server-side split, no flicker, but no significance verdict. Below Grow, Trident AB's free plan gives you one test and 500 impressions a month (App Store listing, September 6, 2026), enough to learn the workflow and nowhere near enough to decide anything. Visually at $15 a month for stores up to 100 orders is close to free and includes unlimited A/B tests.

Can I A/B test prices on Shopify, and which app is cheapest for it?

Yes, with an app; Rollouts does not list prices or discounts among the things a rollout can change. On App Store listings read September 6, 2026, price testing starts at $19.99 a month on Trident AB, $99 on Elevate's Standard plan, $199 on ABConvert's Growth plan, $349 on Intelligems' Unlimited tier, and on Shoplift's Advanced plan at $399 (App Store) or $299 (shoplift.ai). Visually's listing advertises price testing from $15. Cheapest with a mature track record: Elevate at $99.

How much do Shopify A/B testing apps cost?

On App Store listings read September 6, 2026: from $0 (Rollouts, Trident's free plan, SimGym's free install) to $999 a month (Shoplift Pro). The middle of the field sits between $49 and $199: Elevate from $49, Intelligems from $69, Shoplift and ABConvert from $99. Outside the App Store, Convert starts at $299 a month on annual billing and Varify at 199 euros. Intelligems' own site quotes Unlimited at $2,894 a month, or $1,279 on annual billing, for stores up to 200,000 orders.

Is Shopify SimGym the same as A/B testing?

No. SimGym runs AI shoppers with human-like profiles through your storefront and reports which theme they added to cart more often. No real visitor sees either version. Shopify's own Help Center says results might differ from actual buyer behavior. Treat it as a rehearsal before a live test, and note that its listing carries 2.8 stars across 37 reviews as of September 6, 2026.

Which Shopify A/B testing app has the best reviews?

On the App Store on September 6, 2026: Shoplift 4.9 (135 reviews), Elevate 4.9 (140), Intelligems 4.8 (190), Visually 4.8 (144), ABConvert 4.6 (83), Trident AB 4.6 (39). Personizely shows 5.0 across 90 reviews but is a popup tool with testing attached. Shopify's own SimGym sits at 2.8 (37). Convert and Varify have no App Store listing, so no rating.

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

Server-side tools do not add a swap after load: Rollouts assigns the version before the page is sent. Native App Store apps such as Shoplift and Intelligems serve variants through the theme. Script-based platforms such as Convert and Varify run in the browser and rely on anti-flicker masking, which can hold the page for a moment. One question settles it before you buy: where does the split happen?

What happened to Neat A/B Testing?

As of September 6, 2026, neatab.com no longer resolves at all, and the app does not appear in the App Store's A/B testing collection. If you were a Neat user, the closest replacements are Elevate for cheap price tests and Shoplift for theme tests. We wrote up the options in our Neat A/B Testing alternatives guide.

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

Honestly, none of them fix the arithmetic. Detecting a small lift takes tens of thousands of visitors per variant, and a store doing a few thousand sessions a month cannot feed that. Run the numbers in our significance calculator first. If the test cannot conclude in a reasonable window, apply one change, measure it against a baseline, and keep or revert.
