Shogun is a page builder for creating and designing Shopify and BigCommerce pages. CustomFit.ai is a CRO platform for testing and optimizing those pages to increase conversion rate and revenue per visitor. The two tools are not direct competitors. One builds pages, the other optimizes them. If your goal is to improve conversions rather than design capabilities, CustomFit.ai is what you need. If you need both, they work well together.

Shogun helps you build pages faster with a drag-and-drop editor. Its main value is design speed and flexibility, particularly for landing pages and product pages on Shopify and BigCommerce.
CustomFit.ai answers a different question: of all the possible versions of your page, which one actually makes more people buy? It does this through A/B testing, AI-driven traffic allocation, and personalization based on 1000+ visitor attributes.
Shogun does offer A/B testing in its higher-tier "Measure" plan, but it is an add-on feature inside a page builder rather than a purpose-built experimentation platform. The testing is more limited in depth, with fewer targeting options, no AI-driven allocation, and less flexibility in what elements you can test.
CustomFit.ai installs from the Shopify App Store in one click. There is no theme modification and no code to write. The visual editor overlays on your live store, so you are testing real pages on real traffic immediately. You can run your first experiment the same day.
Shogun's setup is also no-code, but building a page in Shogun takes design time, since you are constructing a page from components. For stores that already have pages and want to optimize them, CustomFit.ai is faster to get value from because you are testing what exists rather than rebuilding it.
CustomFit.ai is purpose-built for experimentation:
On results, CustomFit.ai customers average an 11% CVR increase. Bellavita achieved an 11% CVR lift, Kapiva 9.48%, and Chargebee a 40% AOV increase.
Shogun's A/B testing (available on the Measure plan at $249/mo) covers basic variant testing on Shogun-built pages. It works for teams already invested in Shogun who want to run simple page tests, but the experimentation depth, including targeting options, AI optimization, and multivariate support, does not match a dedicated CRO platform.
CustomFit.ai segments visitors across 1000+ attributes, including device, location, traffic source, cart value, purchase history, and behavioral signals. A visitor arriving from a Google Shopping ad sees a different product page than a returning customer who previously bought from you. This personalization runs automatically once you define the rules, with no manual page duplication required.
Shogun offers a "Personalize" feature as a separate module that adds some content personalization capability. It is useful for basic cases but does not reach the depth of a purpose-built personalization engine, particularly for the behavioral targeting that drives D2C revenue.
CustomFit.ai tracks the revenue metrics that matter to D2C brands directly in the platform: revenue per visitor, average order value, add-to-cart rate, and conversion rate, broken down by variant and audience segment. You can see exactly what a winning variant is worth in dollars.
Shogun's analytics focus on page performance, such as views, engagement, and funnel metrics for Shogun-built pages. It integrates with Google Analytics and Shopify analytics for broader reporting, but experiment-level revenue attribution requires a separate setup.
| Plan | CustomFit.ai | Shogun |
|---|---|---|
| Entry | $99/mo (50K MUV) | $39/mo (Build, no A/B testing) |
| A/B testing included | $99/mo | $249/mo (Measure plan) |
| Growth | $249/mo (100K MUV) | Custom |
| Enterprise | Custom | Custom |
| Free trial | 14 days, no credit card | 10-day trial |
Note: To access Shogun's A/B testing features, you need the Measure plan at $249/month. CustomFit.ai includes full A/B testing, personalization, and AI optimization starting at $99/month.
Shogun is the right choice if your bottleneck is page creation speed and design flexibility. If you launch new collections frequently, run many marketing campaigns with dedicated landing pages, or need design components beyond your theme's capabilities, Shogun solves that problem well. Its page builder is mature and widely used. Many effective setups use Shogun for building and CustomFit.ai for optimizing, since they address different parts of the same funnel.
If you're using Shogun and want to add CRO capabilities with CustomFit.ai:
If you are on Shogun's Measure plan mainly for A/B testing, moving to CustomFit.ai at $99/month gives you more testing depth at a lower price, and you can keep using Shogun's page builder at the Build tier.
Does Shogun have built-in A/B testing? Yes, but only on the Measure plan at $249/month. The testing is more limited than a dedicated CRO platform. There are fewer targeting options, no AI-driven optimization, and testing is restricted to Shogun-built pages.
Can CustomFit.ai test Shogun-built pages? Yes. CustomFit.ai's visual editor overlays on any rendered Shopify page, including those built with Shogun. You can create variants without modifying the underlying Shogun page.
Is CustomFit.ai cheaper than Shogun for A/B testing? If A/B testing is your goal, yes. CustomFit.ai starts at $99/month with full testing capabilities. Shogun's A/B testing requires the $249/month plan.
What metrics does CustomFit.ai track that Shogun doesn't? CustomFit.ai tracks revenue per visitor and average order value per experiment variant. That is direct revenue attribution that tells you exactly what each test is worth financially. Shogun's analytics are page-performance-focused rather than experiment-revenue-focused.
Can I use both Shogun and CustomFit.ai together? Yes. This is a common setup: use Shogun to build pages with design speed and flexibility, and use CustomFit.ai to run experiments on those pages and keep optimizing for revenue. They don't conflict.
How does CustomFit.ai's AI optimization work? CustomFit.ai's AI monitors variant performance in real time and gradually allocates more traffic to higher-converting variants before the experiment concludes. This means you are capturing revenue uplift during the test period, not just after declaring a winner.
