Shopify Page Builder Cost Calculator

Compare estimated monthly cost across PageFly, GemPages, Shogun, and Replo for your Shopify store. Enter your pages, whether you need A/B testing, and your store sessions to see which is cheapest and why the winner changes once A/B testing is in play.

A/B testing is the main reason stores buy a page builder for CRO, but each tool prices it differently: GemPages needs the separate GemX app, PageFly bundles it into its Optimize tier, Shogun sells it as an add-on, and Replo builds it in. That is why the cheapest tool changes when you toggle A/B testing.

At about 10 published pages and 50,000 sessions/mo with A/B testing, PageFly looks cheapest, around ~$260/mo less than Shogun.

Sticker price vs true CRO cost: GemPages has the lowest sticker price (~$23/mo), but once you turn on A/B testing, PageFly is cheaper (~$39/mo). The entry price hides the CRO cost: GemPages's A/B testing is sold separately, while PageFly bundles it in.

Performance note: page-builder JavaScript weight varies a lot. Replo (~80 KB, compiles to Liquid and exports cleanly) and Shogun (native Online Store 2.0 sections) are the lightest; GemPages (~240 KB) and PageFly (~340 KB, ~52 mobile Lighthouse) add more. Heavier landing pages can slow paid-traffic conversion, so weigh load speed alongside price.

Why page builder pricing is misleading

Page builders advertise low entry prices, but the number you actually pay depends on A/B testing, the main reason stores buy one for conversion work. GemPages looks cheapest at around $23/mo for unlimited pages, but its A/B testing is a separate GemX app on top. PageFly bundles A/B into its Optimize tier, Shogun sells it as an add-on, and Replo builds it in but caps sessions. That is why the cheapest tool flips depending on whether you need A/B testing.

How we estimate

We pick each tool's realistic tier for your pages and traffic, add A/B testing the way that tool actually charges for it, and add session overage where it applies (Replo bills above 100K sessions on Starter). The numbers track the hedged pricing in our reviews as of June 2026 and round to the nearest dollar. They are estimates for planning, not quotes, and exclude annual-billing discounts, one-off add-ons, and implementation fees. Heavier page-builder JavaScript also carries a performance cost on paid traffic that the price alone does not show.

FAQ

How accurate is this page builder cost calculator?
It gives approximate estimates based on each tool's published pricing as of June 2026, adjusted for your pages, whether you need A/B testing, and your store sessions. Real bills vary with plan options, add-ons, billing changes, and negotiated rates, so treat the numbers as a guide and confirm live rates with each vendor before deciding.
Why does it ask whether I need A/B testing?
Because A/B testing is priced very differently across page builders, and it is the main reason most DTC stores buy one for conversion work. GemPages sells A/B testing as a separate GemX app on top of its base plan, PageFly bundles it into its $39 Optimize tier, Shogun sells it as an add-on, and Replo builds it in (with session caps). Toggling A/B testing is what reveals the true cost of each tool.
Which Shopify page builder is cheapest?
It depends on whether you need A/B testing. Without A/B testing, GemPages is usually cheapest because its base plan includes unlimited pages at around $23/mo. The moment you need A/B testing, PageFly tends to win because its $39 Optimize tier bundles A/B in, while GemPages has to add the separate GemX app. Enter your numbers above to see the crossover for your case.
What about page-load performance?
Price is not the only cost. Page builders inject JavaScript that can slow your landing pages, which hurts conversion on paid traffic. Independent benchmarks put Replo lightest (around 80 KB; it compiles to Shopify Liquid and is the only tool with a clean code-export path), Shogun very light (native Online Store 2.0 sections), GemPages around 240 KB, and PageFly heaviest (around 340 KB, roughly a 52 mobile Lighthouse score). If you spend heavily on ads, weigh that performance tax alongside the subscription price.
Does cheapest mean best?
No. Price is one factor. Replo is the performance and code-export pick, Shogun is the enterprise and theme-safety pick (native sections survive theme swaps), GemPages is the best value for marketers running frequent campaigns, and PageFly has the largest ecosystem and the best-value bundled A/B testing.
