A/B Testing Apps for Shopify, Compared (2026)
Five apps come up whenever merchants search for a Shopify A/B testing (or split testing) app: acceleroi, Intelligems, Shoplift, ABConvert, and VWO. The one-line verdict: acceleroi’s CRO Autopilot runs the whole test for you from $299/mo; Intelligems is the deepest price-and-shipping tester from $69/mo; Shoplift is the highest-rated self-serve pick for product and theme tests from $99/mo; ABConvert scales cleanly with order volume from $99/mo; and VWO is a full experimentation suite (heatmaps, recordings, multivariate) with no published Shopify price. The real difference between them isn’t features, it’s who does the work.
The real question: who does the work?
Every one of these five apps will split your traffic and tell you which version won. That part is commoditized: traffic splitting and a stats engine are table stakes in 2026. What separates them is who does the work before and after the split.
With Intelligems, Shoplift, ABConvert, and VWO, you’re buying testing rails: infrastructure to run the experiment and a statistics engine to read it. Someone still has to find the idea, build the variant in the app’s editor (or with a developer), QA it, launch it, and interpret the result. That someone is you, a hire, or an agency you pay separately. The app doesn’t do that labor for you.
acceleroi’s CRO Autopilot runs that whole loop for you instead: the free AI audit becomes your backlog, AI and a senior strategist build and QA each variant, and you get a Bayesian verdict rather than a spreadsheet to interpret yourself. Full mechanics in the section below.
The honest tradeoff: self-serve is cheaper per month and keeps you in full control of what ships and when. Done-for-you costs more (acceleroi’s plans start at $299/mo; see full pricing), but that price includes the labor. With the self-serve four, the person finding, building, QAing, and reading each test is a real cost too, just paid separately as your own time, a hire, or an agency retainer.

acceleroi CRO Autopilot
acceleroi’s CRO Autopilot is a Shopify app, released September 2026, that runs the entire testing loop for you. It starts with the free AI audit: 48 heuristics scanned against your live site, conversion leaks sized in dollars, no signup, results in about three minutes. That becomes your experiment backlog. AI builds each fix as a variant coded for your theme, a senior strategist QAs it against screenshots before anything ships, and it launches on a capped canary that auto-ramps as it proves out. Verdicts are Bayesian: winners roll out, non-winners stop cleanly, with a reversible path back to control.
Pricing runs Starter $299/mo (1 experiment, up to about 25k monthly visits), Growth $799/mo (3 experiments, 25k-100k visits), Pro $1,799/mo (6 experiments, 100k-300k visits), and Scale $3,499/mo (12 experiments, 300k+ visits, with a dedicated strategist); see full pricing. Only a live experiment is billed: ideas, mockups, QA rounds, and rebuilds never are. Extra launches are +$300 each, confirmed first and capped at $7,490 per 30 days, and a confidently-losing test is credited back. The first experiment ships free, unused experiments roll over, and you can cancel anytime.
It fits merchants who want their CRO program run for them, not another dashboard to manage. The honest limitation: it’s the highest entry price of the five at $299/mo, and it doesn’t test prices, shipping, or checkout. For those, see Intelligems or ABConvert below. More on the model at CRO Autopilot.
Intelligems
Intelligems is a modular Shopify app built for testing what most tools won’t touch: prices, discounts, shipping rates, checkout, and post-purchase offers, alongside standard content tests. It’s self-serve, with an AI-powered visual builder and a full API for custom logic. Statistics run on a Bayesian engine with Monte Carlo simulation, recommending 300+ orders per test group and 7+ day tests.
Pricing is modular and scales with monthly order volume: Smart Content starts at $69/mo, Smart Merchandise and Smart Shipping each start at $112.10/mo, and the all-in-one Unlimited plan starts at $349/mo (App Store starting prices; annual billing saves 17-20%). Smart Pricing, the price-testing module, has its own tiers: Tier 1 covers one price test per month, Tier 2 unlocks unlimited concurrent tests and multi-currency, both with a 3-month minimum. There’s a 14-day free trial, no credit card, though Smart Pricing is excluded from it.
Intelligems fits merchants who specifically want to test prices or shipping (the kind of tests acceleroi doesn’t run) and are comfortable building and reading tests themselves, or through an agency. The honest limitation: Smart Pricing’s 3-month minimum and free-trial exclusion mean you can’t try the price-testing module risk-free before committing. Full breakdown at acceleroi vs Intelligems.
Shoplift
Shoplift is a theme-native Shopify testing app: product pages, landing pages, collections, the homepage, prices, and search, plus full theme tests for rebrands, navigation, and the mini-cart. It’s self-serve, built inside the theme customizer, and its Lift Assist AI generates test suggestions from patterns it’s seen across top Shopify brands. Statistics run on Bayesian predictive analysis.
Pricing is set by monthly unique visitors: Core is $99/mo for up to 50k, Advanced is $399/mo for up to 100k, and Pro is $999/mo for up to 250k. Annual billing brings those down to $74/mo, $299/mo, and $699/mo, a 25-30% saving. There’s a 14-day free trial.
Shoplift carries the best Shopify App Store rating of the group, 4.9 stars across 120 reviews as of September 2026, and it suits merchants who want a self-serve tool with AI-generated ideas and are comfortable building and QAing their own variants. The honest limitation: pricing is set by traffic, not by how many tests you actually run, so a 250k-visit store pays $999/mo (or $699/mo annual) whether it ships one test that month or five. Compare it directly in acceleroi vs Shoplift.
ABConvert
ABConvert is a no-code, self-serve testing app covering prices, product pages, shipping rates, checkout, URL redirects, templates and themes, and offers, all through a visual editor. Its statistical method isn’t published.
Pricing scales with monthly test orders rather than visitors: Starter is $99/mo for 1,000 orders (plus $59 per extra 1,000), Growth is $199/mo for 5,000 orders (plus $39 per 1,000) and adds live guided onboarding, Scale is $399/mo for 15,000 orders (plus $29 per 1,000) and adds monthly test reviews, and Pro is $599/mo for 30,000 orders (plus $24 per 1,000) with white-glove onboarding and a dedicated account manager. Annual billing brings those down to $74/mo, $149/mo, $299/mo, and $449/mo. There’s a 14-day free trial.
ABConvert fits merchants who’d rather pay based on orders than traffic, and who like that more hands-on support (guided onboarding, test reviews, a dedicated manager) is built into the higher tiers instead of sold as a separate retainer. The honest limitation: ABConvert doesn’t publish its statistics methodology, so if you need to know exactly how it calculates significance before trusting a verdict, that detail isn’t available the way it is for the other four. Full comparison at acceleroi vs ABConvert.
VWO
VWO is a general web experimentation suite, not a Shopify-specific app: A/B, split, and multivariate testing, plus heatmaps, session recordings, form analytics, surveys, and funnels, all in one platform. It’s self-serve through a WYSIWYG visual editor, with Bayesian statistics via its SmartStats reporting engine.
Pricing runs across Growth, Pro, and Enterprise plans, but VWO doesn’t publish dollar prices: billing is usage-based and sales-led, with Enterprise fully custom. There’s a 30-day free trial, no credit card required.
VWO fits brands that want one experimentation platform across their whole site, not just Shopify, and value the extra research tools (heatmaps, recordings, surveys) bundled in alongside testing. The honest limitation: with no published pricing, you can’t compare true cost against the other four without booking a demo, and its Shopify listing (free to install, separate VWO subscription required) has zero reviews as of September 2026, so there’s no Shopify-specific track record to check yet.

Which A/B testing app should you pick?
- New Shopify store, first test ever, no dev or design help. acceleroi Starter, $299/mo for 1 experiment (up to about 25k monthly visits). The first experiment ships free.
- Growing store (25k-100k monthly visits), one marketer, no in-house CRO or dev. acceleroi Growth at $799/mo (3 experiments) if you want it run for you, or Shoplift Advanced at $399/mo (up to 100k visitors) if someone in-house can build and QA variants.
- Testing prices, shipping rates, or checkout, not just page content. Intelligems (Smart Content from $69/mo, Smart Pricing on its own tiers) or ABConvert (from $99/mo, scales by order volume); acceleroi doesn’t test these.
- High-traffic store (100k-300k+ visits), lean team, wants execution off their plate. acceleroi Pro at $1,799/mo (6 experiments) or Scale at $3,499/mo (12 experiments).
- Agency or in-house CRO team running many tests, wants full build control. Shoplift Pro at $999/mo (up to 250k uniques, Lift Assist AI for ideas), or Intelligems if price testing is central (Smart Pricing runs on its own tiers with a 3-month minimum; the all-in-one Unlimited plan starts at $349/mo).
- High order-volume store that wants pricing tied to orders, not traffic. ABConvert, from Growth at $199/mo through Pro at $599/mo.
- Enterprise brand testing beyond Shopify, wants heatmaps, recordings, and surveys alongside testing. VWO, priced by demo.

Frequently Asked Questions
What’s the cheapest A/B testing app for Shopify?
Intelligems is cheapest, Smart Content starts at $69/mo. Shoplift and ABConvert both start at $99/mo. acceleroi’s CRO Autopilot starts at $299/mo, but that price includes the labor of building and QAing each test, not just infrastructure. VWO doesn’t publish Shopify pricing.
Which Shopify A/B testing app has the best rating?
Shoplift leads with 4.9 stars across 120 reviews as of September 2026. Intelligems and ABConvert are both at 4.7 stars (164 and 72 reviews). VWO’s Shopify listing has 0 reviews. acceleroi has no public Shopify App Store listing yet; it installs directly through acceleroi’s own app.
Can I test prices with these apps?
Yes, with Intelligems (Smart Pricing: 1 test/month on the entry tier, or unlimited concurrent tests with multi-currency, 3-month minimum) and ABConvert (included from $99/mo). Shoplift also lists prices among what it tests. acceleroi does not; it focuses on page and UX experiments.
Do I have to build my own tests, or does the app do it?
With Intelligems, Shoplift, ABConvert, and VWO, you or your agency find the idea, build the variant, QA it, and read the results. The app provides the testing rails. acceleroi’s CRO Autopilot runs that loop for you instead: AI builds each variant, a strategist QAs it, and you get a Bayesian verdict without building anything yourself.
How much does A/B testing cost on Shopify?
Self-serve tools start between $69/mo (Intelligems) and $99/mo (Shoplift, ABConvert), though your own time or an agency retainer to run the tests is a real cost on top. acceleroi’s CRO Autopilot runs $299/mo to $3,499/mo depending on how many experiments you need; see full pricing. VWO is usage-based and demo-priced.
