Shoplift vs Intelligems: they solve different jobs
Shoplift is the theme and section tester with a Bayesian engine, from $99/mo. Intelligems leads price and offer testing at its $499/mo tier. A neutral, no-spin comparison of what each actually tests, what it costs, and when to run both. Prices verified July 2026.
Search Shoplift versus Intelligems today and the page that ranks is Shoplift's own comparison, which is not a neutral source. This one is neither vendor's. The honest headline is that these two apps rarely compete for the same test: Shoplift is built to test your theme and layout, and Intelligems is built to test your prices and offers. Which one you want depends on what you are trying to change, and for plenty of stores the answer is both.
This is a merchant-first head-to-head: what each app tests, what each tier costs, how each calls a winner, and the run-both pattern that pairs one for the storefront with one for pricing. Prices are verified July 2026 on the Shopify App Store and each vendor's site; re-check before you buy, since testing apps change tiers often.
Different jobs, same store
TL;DR Shoplift changes what shoppers see (theme, layout, copy). Intelligems changes the economics they get (price, shipping, offer). Same store, different levers.
The cleanest way to read this matchup is to ask what part of the store you want to change. Shoplift edits the storefront theme and measures which layout converts better. It works at the template and section level, so you can test a product-page arrangement, a hero, a collection grid, or navigation, and it never touches price, discounts, or shipping. Two variants per test, theme-native rendering, no page flicker (repo notes, July 2026).
Intelligems reaches the part a theme tester cannot. It works around Shopify's native price-test limits with cart-transform functions, which quietly adjust what a shopper is charged at the cart and checkout without editing your product records, and it scores each variant on profit per visitor using your real costs rather than raw conversion (repo notes, July 2026). That is a fundamentally different experiment: you are testing the money a shopper spends and the margin you keep, not the pixels they look at. A layout test can tell you which hero converts better; only a price test can tell you whether a $2 price bump costs you any orders, and Intelligems is built to answer the second question.
So the decision is rarely Shoplift or Intelligems on one question. It is which question you are asking. A theme test and a price-presentation test are two different jobs, and each app owns one of them.
What each one actually tests
TL;DR Shoplift owns theme, template, section, URL, and device splits. Intelligems owns price, shipping, and offer tests. Only Intelligems reaches checkout economics.
Here is the head-to-head at a glance, with our own pre-launch app shown for context and disclosed as such.
| Tool | Built to test | Headline feature and tier |
|---|---|---|
| Shoplift | Theme, template, and section layout, plus URL and device splits | Price testing (beta): Advanced tier, $399/mo |
| Intelligems | Price, offer, and shipping economics via cart-transform functions | Price testing: Plus tier, $499/mo |
| StorePilot (ours, pre-launch) | Friction it spots in real behavior, judged on revenue per visitor | Honest stats on any plan: free 3 months, then ~$129/mo |
Verified July 2026 on the Shopify App Store and each vendor's site; tiers change often, so confirm before you buy. The third row is our own pre-launch app, disclosed as such and shown for context only. For the wider field, see the full A/B testing app comparison.
The capability gap is concrete. Shoplift caps a test at two variants and renders variants natively in the theme, which keeps the page from flickering while it loads (repo notes, July 2026). What it does not do is test shipping or checkout, because those are pricing economics, not theme changes.
Intelligems runs price, offer, and shipping tests, and it reads price tests on orders rather than sessions, which is the correct denominator when a lower price can win conversion while quietly losing margin (repo notes, July 2026). If your test involves a number a shopper pays, Intelligems can run it and Shoplift cannot. If your test involves what a shopper sees, Shoplift is the tighter, cheaper tool.
Segmentation is where the tiers start to matter. Shoplift's Core plan covers template, theme, and URL tests plus a mobile-vs-desktop split, and its Advanced plan adds country, region, and subscription segmentation along with Lift Assist, which auto-generates branded variants (Shopify App Store, verified July 2026). Intelligems keeps its heaviest segmentation, subscription-price and multi-currency testing, on the $999/mo Blue tier (intelligems.io, verified July 2026). If you run a single storefront in one currency, neither ceiling will bother you; if you sell across regions or run subscriptions, price the tier that carries the segmentation you actually need before you commit.
Pricing, tier by tier
TL;DR Both start cheap (Shoplift $99, Intelligems $79) but gate their headline feature 4–6x higher: Shoplift price testing at $399/mo, Intelligems price testing at $499/mo (verified July 2026).
| Plan | Price | What it unlocks |
|---|---|---|
| Shoplift Core | $99/mo ($74/mo annual) | Template, theme, and URL tests, mobile-vs-desktop segmentation, Bayesian analysis, up to 50k monthly visitors |
| Shoplift Advanced | $399/mo ($299 annual) | Adds price testing (beta), advanced segmentation, Lift Assist variants, and GA4 |
| Shoplift Pro | $999/mo ($699 annual) | Adds a dedicated success manager, strategy sessions, and a storefront audit |
| Intelligems Core (Redirect only) | $49/mo | Redirect tests only, for stores under 3,000 monthly orders |
| Intelligems Core | $79/mo ($59 annual) | Content and landing-page tests |
| Intelligems Plus | $499/mo ($374 annual) | Adds price testing, plus shipping rates and thresholds |
| Intelligems Blue | $999/mo ($749 annual) | Adds subscription-price and multi-currency tests |
Prices verified July 2026 on the Shopify App Store and intelligems.io; both apps offer a 14-day free trial. Annual figures shown as the monthly equivalent. Confirm live, since testing apps change tiers often. More on tier math in our Shopify A/B testing pricing guide.
The money line of this comparison sits in one row-pair. Shoplift's price testing costs $399/mo and its own listing marks it as a beta; Intelligems' price testing costs $499/mo and is the app's core competency, with cart-transform mechanics and profit scoring behind it (both verified July 2026). A hundred dollars a month cheaper does not make the two equivalent, so read the $399 tier as an entry to a beta feature, not a discount on the leader.
Watch the entry asymmetry too. Both apps are inexpensive to start (Shoplift Core $99/mo, Intelligems Core $79/mo, verified July 2026), and both put their headline capability four to six times higher. Shoplift meters by monthly unique visitors, with Core covering up to 50,000 (Shopify App Store, verified July 2026), so its cost climbs as you grow. Intelligems' cheapest $49/mo tier only runs redirect tests and is limited to stores under 3,000 monthly orders (intelligems.io, verified July 2026), which makes it a narrow starting point rather than a real price-testing plan.
How each calls a winner
TL;DR Both are Bayesian, so statistics is not the tiebreaker. Intelligems adds Monte Carlo simulation and its own honesty bar of 300+ orders per group before you read a test.
It is tempting to pick on statistics, but here the two apps land in the same family. Shoplift's Shopify App Store listing describes a Bayesian predictive analysis, included from the Core tier (July 2026). Intelligems documents a Bayesian statistical model with Monte Carlo simulations, and surfaces probability-to-beat-control, probability-to-be-best, and a 95% confidence interval around the uplift (docs.intelligems.io, July 2026). Neither leaves you eyeballing raw numbers, and neither is meaningfully more honest by method.
Where Intelligems is usefully strict is its own runtime guidance: at least 300 orders per test group and at least seven days before you call a result (docs.intelligems.io, July 2026). Because price tests read on orders, that bar is a real screen. A store doing 500 orders a month will wait weeks to gather 300 per variant, which is a good reason to size the test before you start. Whichever app you use, judge a price test on revenue per visitor and your contribution margin, not conversion rate, and read our note on reading results honestly so you do not stop a test the moment it looks good.
Who should pick which
TL;DR Theme and copy tests go to Shoplift. Price, shipping, and offer tests go to Intelligems. Thin traffic goes to a different method entirely.
Pick Shoplift if your roadmap is mostly layout and content: product-page structure, hero, sections, navigation, collection grids. You get section-level control and a Bayesian winner call from $99/mo (Shopify App Store, verified July 2026), and you avoid paying for price-test machinery you will never run.
Pick Intelligems if the experiment involves a number the shopper pays: list price, bundle price, a discount, a free-shipping threshold, or a shipping rate. Just confirm you clear its honesty bar first, roughly 300 orders per variant over a week or more (docs.intelligems.io, July 2026), or the test will not settle.
Pick neither yet if your store runs thin. Under a few thousand sessions a month, no fixed-horizon splitter reaches significance in a reasonable window, and Intelligems price tests need order volume most small stores do not have. That low-traffic case is the one StorePilot (ours, pre-launch, said plainly) is built for: it watches real behavior, finds the friction worth testing, builds the variant, and judges it on revenue per visitor with deterministic honest stats and no early winners, on any plan. It is free for the first three months, then about $129/mo at the founding rate. None of this head-to-head depends on it; both Shoplift and Intelligems are shipping tools you can install today. If your store is small, start with the low-traffic testing playbook before you pay for either splitter.
The run-both pattern
TL;DR Shoplift for the storefront, Intelligems for pricing: Core $99 plus Plus $499 comes to $598/mo, versus Shoplift Advanced alone at $399 with beta price tests and a two-variant, no-shipping limit.
Because they own different levers, running both is a legitimate setup, not a redundancy. The common split is Shoplift Core at $99/mo for layout and content tests and Intelligems Plus at $499/mo for price and shipping tests, which totals $598/mo (both verified July 2026). You get the best theme tester and the best price tester, each doing the job it is strongest at.
The alternative is Shoplift Advanced alone at $399/mo, which bundles theme testing with its price-testing beta. That saves roughly $200/mo against running both, but you trade down to a beta price feature, two variants per test, and no shipping or checkout tests (verified July 2026). If pricing is a serious, ongoing line of work for you, the run-both stack is usually worth the difference; if a price test is an occasional curiosity, Advanced may cover it. One housekeeping note when running both: keep their tests off the same shoppers on the same metric, so neither engine is reading a page the other app is also changing.
The near-tie in ratings supports treating this as a two-good-tools decision rather than a winner-take-all one: Shoplift at 4.9 stars over 129 reviews and Intelligems at 4.7 over 162, both 94% five-star (Shopify App Store, July 2026). Merchants like both; they just use them for different work.
The honest takeaway: pick by the lever you want to pull. Theme and layout point to Shoplift, price and offers point to Intelligems, and when both matter, running both is a real and common option. Name the test first, and the tool picks itself.
Questions merchants keep asking
Shoplift vs Intelligems: what is the real difference?
They test different things. Shoplift is built to test your theme and layout at the template and section level, from $99/mo (Shopify App Store, verified July 2026). Intelligems is built to test your prices, offers, and shipping using cart-transform functions, with price testing on its $499/mo Plus tier (intelligems.io, verified July 2026). Same store, different levers, so the two apps rarely compete on the same question.
Is Shoplift or Intelligems better for price testing?
Intelligems, clearly. Price testing is its core competency: it works around Shopify's native price-test limits with cart-transform functions and scores each variant on profit per visitor using your real costs (repo notes, July 2026). Shoplift added price testing too, but its Shopify App Store listing marks it as a beta and it lives on the $399/mo Advanced tier (verified July 2026). Cheaper on paper, but beta and not the same depth.
How much does Intelligems cost in 2026?
Intelligems has four tiers (intelligems.io and Shopify App Store, verified July 2026): a Redirect-only Core at $49/mo for stores under 3,000 monthly orders, a $79/mo Core ($59 annual) for content and landing-page tests, a $499/mo Plus ($374 annual) that unlocks price testing plus shipping rates and thresholds, and a $999/mo Blue ($749 annual) that adds subscription-price and multi-currency tests. Price testing needs the $499 Plus tier. All plans carry a 14-day free trial.
How much does Shoplift cost in 2026?
Shoplift has three tiers (Shopify App Store, verified July 2026): Core at $99/mo ($74/mo on annual billing), Advanced at $399/mo ($299 annual), and Pro at $999/mo ($699 annual). Plans are metered by monthly unique visitors, and Core covers up to 50,000. Price testing (beta) is gated to the Advanced tier. Every plan includes a 14-day free trial.
Which has better reviews, Shoplift or Intelligems?
It is close to a tie on the Shopify App Store (July 2026). Shoplift holds 4.9 stars across 129 reviews, with 94% five-star. Intelligems holds 4.7 stars across 162 reviews, also 94% five-star. Shoplift has the higher average; Intelligems has more reviews. Neither rating gives you a reason to pick one over the other, which fits the idea that they serve different jobs.
Are Shoplift and Intelligems both Bayesian?
Yes, so statistics is not the tiebreaker. Shoplift's listing describes a Bayesian predictive analysis included from its Core tier (Shopify App Store, July 2026). Intelligems documents a Bayesian statistical model with Monte Carlo simulations, and reports probability-to-beat-control, probability-to-be-best, and a 95% confidence interval around the uplift (docs.intelligems.io, July 2026). Both call winners with Bayesian methods, so choose on what they test, not how they read results.
Can I run both Shoplift and Intelligems at the same time?
Yes, and many stores do: Shoplift for the storefront and Intelligems for pricing. Shoplift Core at $99/mo plus Intelligems Plus at $499/mo comes to $598/mo (both Shopify App Store / intelligems.io, verified July 2026). Keep their tests from overlapping the same shoppers on the same metric so the data stays clean, and read each on the metric that fits: layout on conversion, price on profit per visitor.
Does Shoplift test shipping or checkout like Intelligems?
No. Shoplift tests themes and sections, with two variants per test and no shipping or checkout tests (repo notes, July 2026). Shipping rates and free-shipping thresholds are pricing economics, not theme changes, so they sit outside what a theme tester can split. Intelligems reaches them on its $499/mo Plus tier (intelligems.io, verified July 2026), which is one of the clearest lines between the two apps.
How many orders do I need before I can trust an Intelligems price test?
Intelligems' own guidance is at least 300 orders per test group and at least seven days of runtime before you read a result (docs.intelligems.io, July 2026). Price tests read on orders, not sessions, so a store doing a few hundred orders a month will wait a while to clear that bar. It is a concrete honesty check, and it screens out low-volume stores from price testing regardless of which app they use.
Which should a low-traffic store pick, Shoplift or Intelligems?
Neither is a great fit under a few thousand sessions a month. Every fixed-horizon split test needs real volume, and Intelligems price tests need 300+ orders per group before you read them (docs.intelligems.io, July 2026). A thin-traffic store is better served by bolder changes, pooled tests, or an apply-and-measure method with holdbacks. See the low-traffic playbook for the honest options.
