ABConvert and Atchoo! both live in the Shopify A/B testing category, but they cover different ground. ABConvert is a multi-tool: price testing, shipping-rate testing, checkout tests, product page and content tests, and URL/theme split tests under one roof. Atchoo does one thing, product page template testing, and optimizes everything around doing that one thing quickly and cleanly. Here’s an honest comparison to help you work out which shape of tool fits your store.

Short version: if your hypotheses are about what you charge, product prices or shipping rates, or about checkout, ABConvert covers territory Atchoo deliberately doesn’t. If your hypotheses are about the product page itself, Atchoo’s template approach is simpler, lighter, and built exactly for that.

What ABConvert does

ABConvert is a broad testing toolkit for Shopify. Its capabilities span several experiment types:

  • Price testing, showing different prices to different visitor groups and measuring the revenue impact.
  • Shipping rate testing, experimenting with shipping thresholds and rates, which is a genuinely underrated lever since shipping cost is a top reason for cart abandonment.
  • Checkout, product page and content testing, covering more of the funnel than pricing alone.
  • URL and theme split testing, sending portions of traffic to different URLs or different themes to compare bigger structural changes.

It also offers audience targeting by country, UTM and customer type, so you can direct experiments at specific segments. That breadth is the pitch: one app, several experiment types. We won’t quote ABConvert’s pricing or enumerate plan limits here because those details change, check their listing and pricing page for the current picture. Qualitatively, it’s a capable multi-purpose tool, and the trade-off that comes with multi-purpose tools is that each mode carries its own setup considerations and caveats.

What Atchoo does

Atchoo! A/B tests product page templates inside your existing theme:

  1. You create an alternate product template using Shopify’s native template suffixes (e.g. product.variant-b), no theme duplication, no code.
  2. Each visitor is deterministically assigned to a variant via a first-party cookie, so the same visitor always sees the same version. The split is 50/50 by default and configurable.
  3. Variant visitors see the alternate template through Shopify’s native template view mechanism.
  4. Product views and add-to-cart events are tracked in real time through a Shopify app proxy, first-party, no third-party cookies, with traffic-source/UTM breakdowns.
  5. Bayesian analysis calls the winner.

The metric focus is add-to-cart rate: the closest controllable proxy to revenue for a product page change. Anti-flicker is scoped only to product pages with an active test and has a hard failsafe, so it can never blank out the rest of your storefront.

What Atchoo doesn’t do: price testing, checkout testing, sitewide testing, personalization, or heatmaps. That’s a deliberate scope, not a roadmap gap.

Testing approach: focused template swap vs broad toolkit

The interesting comparison here is mechanical, because the mechanism determines the day-to-day experience.

ABConvert’s breadth means it reaches parts of the funnel Atchoo doesn’t touch. Its price and shipping tests change what visitors pay rather than what they see, a different experiment class with customer-trust implications worth thinking through first (our post on price testing risks goes deeper). Its URL and theme splits compare bigger units, a whole alternate page URL or a whole alternate theme, which is powerful for structural questions but means more surface area to build, keep in sync, and dismantle afterwards. A redirect-based split also introduces the redirect itself into the visitor experience, which you’ll want to test carefully on slow connections.

Atchoo’s template swap stays inside one theme. Control and variant are two templates sharing the same theme settings, sections, and snippets; the visitor never changes URL, and there’s no second theme or page to maintain. When you edit your theme, both variants inherit the edit. When the test ends, you keep the winning template and delete the loser. We’ve written more about why this matters in Shopify template testing explained.

Both apps can test product pages, so if that’s your target, the question becomes which mechanism you prefer: Atchoo’s single-purpose native template swap with add-to-cart analytics, or ABConvert’s broader toolkit where product page testing sits alongside many other modes. Match the tool to the range of tests you actually plan to run.

Analytics

ABConvert reports across its various test types with conversion- and revenue-oriented metrics; the specifics vary by experiment type, so evaluate the dashboards against the tests you actually plan to run.

Atchoo’s analytics are narrower and deeper on one job: add-to-cart rate per variant, tracked first-party in real time, with a Bayesian engine that tells you the probability each variant is the winner rather than a p-value you have to interpret. (If the Bayesian/frequentist distinction is new to you, our comparison of Bayesian vs frequentist A/B testing explains why we chose Bayesian.) The UTM/traffic-source breakdown lets you spot when a variant wins with one audience and loses with another.

Add-to-cart as the primary metric is a deliberate choice: it’s high-volume, so tests conclude faster, and it responds directly to product page changes rather than being diluted by everything that happens between cart and checkout.

Pricing philosophy

Atchoo’s pricing is flat and published: $39/mo (or $399/yr) for the Pro plan with full A/B testing and Bayesian analysis, with a 14-day free trial. A Free plan and a $9.99/mo Advanced plan exist for template management without testing. Flat pricing means costs don’t scale with your traffic, details on the pricing page.

For ABConvert, check their current pricing directly; we’d rather point you at the source than risk quoting stale numbers. When you compare, look at how each app’s pricing behaves as your traffic and order volume grow, not just the entry price.

Who should pick which

Pick ABConvert if:

  • You want to test product prices, shipping rates, or checkout, Atchoo doesn’t do any of these.
  • You want URL-level or theme-level split tests for big structural experiments.
  • You want audience targeting by country, UTM or customer type, and value several experiment types inside one app.

Pick Atchoo if:

  • Your testing roadmap is mostly product page work: images, copy, layout, trust signals, CTAs.
  • You want the lightest possible mechanism, native Shopify templates, one theme, no redirects.
  • You want deterministic visitor assignment and first-party tracking without third-party cookies.
  • You prefer a flat monthly price and a tool that’s easy to reason about.

Frequently asked questions

Can Atchoo test shipping rates or prices?

No. Atchoo tests product page templates only. If pricing, shipping and checkout experiments are central to your plans, ABConvert’s scope matches that better.

Do I need to duplicate my theme to test with Atchoo?

No. Variants are alternate templates inside your existing theme, created with Shopify’s built-in template suffix system. There’s no second theme to maintain or clean up.

Which is better for a low-traffic store?

Template tests measured on add-to-cart rate tend to reach conclusions on less traffic than revenue-based price tests, because add-to-cart events are far more frequent than orders. See our guide to A/B testing low-traffic stores.

The bottom line

ABConvert is a legitimate multi-tool: if your growth questions are about what you charge, how you ship, and how your checkout performs, it covers experiments Atchoo intentionally leaves alone. Atchoo is the focused option: product page template testing with native Shopify mechanics, deterministic assignment, first-party tracking, and Bayesian add-to-cart analysis, at a flat price. Match the tool to your actual testing roadmap, and for the full landscape, see our roundup of the best Shopify A/B testing apps and the complete guide to Shopify A/B testing.
