Best Shopify A/B testing tools (2026) Best Shopify A/B testing tools (2026)

Most Shopify A/B testing tools do one job well and everything else adequately. Shoplift swaps themes and templates. Intelligems tests prices and margin. ABConvert does the basics cheaply. The enterprise suites do everything and cost accordingly.

So the question isn't which tool is best. It's what you're actually trying to test — a template, a price, a checkout, or your whole storefront — because that single answer eliminates most of this list.

At a glance

Two columns, two rules: published prices are real figures read from the vendor's own page, and the cost tier is qualitative for every row. Optimizely publishes no entry price, so its cell says so. Mtrix doesn't publish a list price either, so it says so too.

How we evaluated

Four things, in this order:

1. What it can actually test. A tool that swaps templates cannot test a price. A tool that tests prices cannot restyle a section. This is the axis that matters and it's the one most listicles skip.
2. Whether it flickers. Client-side tools rewrite the page after it loads. Shoppers see the original for a moment, then the variant. Anti-flicker snippets fix the flash by hiding the page until the script runs — which adds blank screen time to every single pageview, including for visitors who aren't in the test.
3. What it measures. Conversion rate is not profit. A price test that lifts conversion 8% and cuts margin 12% is a loss you'll book as a win.
4. Published price, read from the vendor's own page on 25 July 2026. Where a vendor doesn't publish, we say so rather than guess.

We didn't score on review counts. A 4.9 from 117 reviews and a 4.9 from 449 reviews tell you about install base, not fit.

What actually breaks Shopify A/B tests

Three failure modes cost more than any tool choice.

Not enough traffic. Detecting a 10% lift on a 5% baseline conversion rate takes tens of thousands of visitors per variant. Below roughly 10,000 monthly visitors, most tests you run will be mathematically inconclusive no matter which tool renders them. Test higher-frequency events — add-to-cart rather than purchase — or pool traffic across all product pages instead of testing one.

Calling it early. A 20% lift after 200 visitors means nothing. Checking daily and stopping when the number looks good inflates false positives dramatically. Set the sample size before you start.

Testing where you can't measure. This is the one that's about to get worse. Shopify's Checkout Extensibility deadline is 26 August 2026 — every non-Plus store gets auto-upgraded, and Additional Scripts and app ScriptTags on the Thank You and Order Status pages are replaced, not migrated. Anything you pasted into Additional Scripts — tracking pixels, GTM containers, affiliate scripts — stops reporting. If your conversion data goes quiet in September, that's why. (checkout.liquid is not part of this date: it was always Plus-only and its deadline was 28 August 2025.)

The tools

1. Shoplift — for theme and template tests

$99 / $399 / $999 per month on their App Store listing · the same three plans at $74 / $299 / $699 on shoplift.ai, billed annually and banded by monthly visitors · 4.9 (117 reviews)

Shoplift integrates into Shopify's own theme customiser, so you duplicate a theme, edit the copy, and test the two against each other. Zero flicker, because the swap happens at the theme level rather than by rewriting the DOM.

Choose Shoplift if your tests are "does this homepage layout beat that one" or "does this product template convert better." That's the most common testing job on Shopify and Shoplift is the cleanest way to do it.

Limits: it tests themes and templates. It won't test a price, and it won't restructure your checkout.

2. Intelligems — for price, margin and offer tests

From $69/mo · 4.8 (154 reviews)

The only tool on this list built around profit rather than conversion rate. Test price points, shipping thresholds, discount depth and bundle offers, and read the result as profit per visitor net of margin — which is the number that actually decides whether a price test won.

Choose Intelligems if you're testing what things cost, not what they look like.

Limits: price testing generally sits on a higher tier than the entry plan — check which tier covers the test type you need before committing. It's a testing layer, not a page builder.

3. ABConvert — for the lowest-cost entry

$99 / $199 / $399 / $599 per month · 4.7 (72 reviews)

Covers price, shipping and template testing from the entry plan. The ladder meters on test orders, not on visitors who never saw the test, with per-1,000 overages above each plan's allowance — which is the fairest metering design in this set, and it means the bill rises with the success of the test. If Intelligems' module tiering puts the test type you want out of reach, this is the pragmatic alternative.

Choose ABConvert if budget is the binding constraint and you need price tests specifically.

4. Visually.io — for visual editing and personalisation

Paid from $15/mo · the App Store's "free plan" is development stores only · 4.7 (120 reviews)

A no-code visual editor paired with personalisation, so the same tool that runs the test can also target the variant at a segment.

Choose Visually if you want one tool for testing and on-site personalisation, and you'd rather drag than write Liquid.

Limits: performance has been a recurring theme in third-party reviews of client-side visual editors generally — measure your own Core Web Vitals before and after installing any of them.

5. Shopify Rollouts — native, nothing to install

Included with Shopify · rollouts on Basic or higher, experiments on Grow or higher

Shopify ships native whole-configuration testing. Since 5 June 2026 that covers checkout and customer-accounts configurations as well as themes. It's free, it's first-party, and there's no third-party script on your storefront.

Choose Rollouts if you want to run an occasional whole-configuration test and don't want another subscription or another script.

Limits: whole configurations only, never elements. Online-store checkouts only — headless and custom storefronts aren't supported. A checkout experiment reports one metric, checkout conversion rate, and no significance or confidence figure appears on Shopify's Rollouts analytics page.

6. Mida — replay-led testing

Free plan available · paid listed at $299/mo · 4.9 (449 reviews)

Primarily session replay and heatmaps with basic A/B testing attached. The generous free tier and large install base make it a common first tool.

Choose Mida if you want to watch sessions first and test second, on a small budget.

7. Convert.com, VWO and Optimizely — the CRO suites

Convert from $399/mo · VWO from $499/mo · Optimizely publishes no entry price

Full A/B, multivariate and split-URL testing, mature statistics, and in VWO's and Optimizely's case server-side testing. Built for teams running structured experimentation programmes across more than one channel.

Choose one of these if you have a dedicated CRO person or agency, you test beyond Shopify, and procurement is not a problem.

Limits: none of them know what a Shopify order is without configuration. You're wiring revenue data in, not reading it natively.

8. Mtrix — for testing the whole storefront, including checkout

Custom pricing · platform tier

Mtrix is not a testing app. It's the platform the store runs on — or a script on the store you already have — with testing built into it rather than bolted alongside.

What that changes:

• Four test types — A/B, multivariate, split URL and mask URL — plus a multi-armed bandit that shifts traffic toward the winner while the test is still running.
• Server-side bucketing. The variant is chosen before the page is sent, so there's no flash of original content and no anti-flicker snippet slowing down every visitor.
• Test the checkout — on a store built on Mtrix. Both a native Mtrix checkout and keeping your existing one are supported, and you can A/B test one against the other. (On a store that stays on Shopify, Mtrix gives you experiments, replay, analytics, error tracking and performance monitoring on your storefront; Shopify's hosted checkout stays Shopify's.) Order and refund data lands through a server-side webhook. Across Mtrix's own clients' checkout tests, the Mtrix checkout converted 14% better than Shopify's checkout.*
• Many tests at once, read honestly. Run overlapping experiments with mutual exclusion so they can't contaminate each other, then read the result as the winning combination or as each test on its own.
• Revenue per visitor as a first-class metric, alongside conversion rate and add-to-cart rate, with probability-to-be-best rather than a bare p-value. Change the traffic split mid-flight. Auto-complete on a visitor count, a date, or a revenue threshold.
• The session behind every result. The replay, heatmap, error and Core Web Vitals data live in the same platform, on the same script. When a variant loses you can watch someone lose it.
• No Mtrix transaction fee. Payment-processor fees only.

Choose Mtrix if you're already paying for a testing app, a replay tool, an analytics tool and a page builder, and the wiring between them is your problem — or if the thing you most need to test is the checkout.

Who should not move to a platform

Straight answer, because this is where most comparison pages start lying.

Stay on Shopify with a testing app if:

• You depend on niche Shopify apps. Shopify's app ecosystem runs to thousands of apps. If your subscriptions, loyalty programme, or 3PL integration lives there, that's a real reason to stay, and no consolidation argument outweighs it.
• You're under ~10,000 monthly visitors. You don't have a tooling problem, you have a sample size problem. Shoplift at $99/mo or a free tier is the correct spend at that stage.
• You only test templates. Shoplift does that job well for $99. Don't buy a platform to do one thing.
• You just replatformed. Doing it twice in a year is a tax on your team, not a strategy.

Mtrix is priced at the platform tier, not the app tier. It's built for brands where a single percentage point of conversion is worth more than the subscription — and if that isn't you yet, one of the apps above is the better answer today.

Free and low-cost options

• Shopify Rollouts — included, native theme testing.
• Mida — free plan available.
• Visually.io — a free plan is listed, but it covers development stores only. Read that before you plan around it.

A free tier is a good way to see whether a tool's reporting makes sense to you. It's a poor way to run a real test: free tiers cap the traffic volume that statistical significance depends on.

Mtrix isn't on this list — it runs a one-month free trial, not a free tier. If your constraint is budget rather than capability, one of the three above is the honest answer.

How to choose, in one pass

1. Write down the one thing you most want to test this month. A template, a price, an offer, or the checkout.
2. Template → Shoplift. Price or offer → Intelligems, or ABConvert on a budget. Checkout, or all of the above → a platform.
3. Check your traffic. Under ~10,000 monthly visitors, pick the cheapest tool that can run the test and spend the difference on getting more traffic.
4. Check the flicker. Load a variant on a throttled mobile connection and watch whether the original renders first.
5. Check what happens on 26 August 2026. If your tracking depends on Additional Scripts or custom checkout code, fix that before you start a test you won't be able to measure.

FAQ

Test your whole storefront, not one template

Mtrix runs experiments on every page — client-side or server-side, on the store you already have or built entirely in Mtrix — and shows you the session, the speed and the revenue behind every result.

* Measured across 350,000+ sessions, tested side by side against Shopify's checkout in the same period, over two years of tests. Mtrix's own client results, not a guarantee of what a new store will see.
