PageFly x Rubik: The Veteran Page Builder Meets Variant Images & Combined Listings (2026)
PageFly is the page builder that’s been on Shopify longer than most apps in your entire stack. Launched September 2017, 200,000+ merchants, 5,733 reviews at 4.9 stars. Those numbers make it the most-reviewed page builder on the Shopify App Store by a wide margin. GemPages has 3,621 reviews. Instant has 297. PageFly has been the default answer to “which page builder should I install?” for almost 8 years. And it pairs with both Rubik apps (Variant Images for gallery filtering, Combined Listings for cross-product grouping) the same way every other supported page builder does: theme app blocks, Shadow DOM isolation, no conflicts.
This guide covers how Rubik Variant Images and Rubik Combined Listings work inside PageFly product pages, what PageFly does well, where it differs from GemPages and Instant (we covered both in separate guides), and the honest caveats you should know before building your variant-heavy PDP on PageFly.

About PageFly
PageFly is a Built for Shopify page builder that positions as “#1 Shopify page builder” by install count, and the numbers support it: 200,000+ merchants and 5,733 reviews. The company is Vietnam-based (like GemPages), launched in September 2017, and has been iterating for almost 8 years. That tenure matters because it means PageFly has been tested across more Shopify theme versions, more API changes, and more edge cases than any newer alternative.
PageFly is one of our 7 officially supported page builders (alongside GemPages, Instant, Beae, EComposer, Foxify, and Replo). It uses a theme extension approach to publish pages, works with both OS 1.0 and OS 2.0 themes, and supports 130+ third-party app integrations including Klaviyo, Judge.me, Loox, and product bundle apps.
Pricing is the simplest in the page builder category: Free (1 published page, all features included), Pay as you go $18/mo (3+ published pages), Unlimited $99/mo (unlimited pages). No feature gating between tiers. Every plan gets every feature. The only difference is how many pages you can publish. That’s refreshingly straightforward compared to GemPages’ 4-tier structure or Instant’s feature-gated plans.
Why Rubik apps on PageFly
Same reason as on any page builder: PageFly controls the page layout, Rubik controls the variant logic. PageFly builds your hero section, trust badges, testimonials, FAQ accordion, buy box arrangement. It doesn’t:
- Filter the product gallery per variant. Customer picks Size Medium on the Navy hoodie, the gallery should show only Medium-specific photos. That’s Rubik Variant Images.
- Link separate products as visual variants. 8 colorway products grouped with swatches on collection cards and PDPs. That’s Rubik Combined Listings.
Three layers: PageFly (page structure) + Rubik Combined Listings (cross-product grouping) + Rubik Variant Images (in-product gallery filtering). All three render via OS 2.0 theme app blocks. All three are Built for Shopify. No conflicts.
Combined Listings + Variant Images inside PageFly
Both Rubik apps render as theme app blocks inside your PageFly product page template. The workflow:
- Rubik Combined Listings app block goes in the variant picker area. It renders the swatch row (color dots, image swatches, labeled buttons) that links separate products together. Customer clicks a swatch, the page redirects to that product’s URL.
- Rubik Variant Images app block goes in the gallery area. It filters the product media so only the selected variant’s photos (and videos, and 3D models) show. Customer picks a size, the gallery updates in place.
- PageFly handles everything else. The surrounding layout, CTA styling, trust elements, description sections, review embeds, cross-sell blocks.
Both Rubik apps render inside isolated Shadow DOMs, so PageFly’s CSS (fonts, colors, button radii, spacing) stays exactly as you designed it. Nothing bleeds in from the swatch row or gallery filter. Nothing bleeds out from PageFly into the Rubik components.
The full PDP stack on a PageFly page for a hoodie with 8 colorways, each with 3 sizes:
- PageFly builds the page layout (hero, badges, descriptions, FAQ, reviews)
- Rubik Combined Listings adds 8 color swatches linking to 8 separate product pages
- Rubik Variant Images filters the gallery per size selection (S/M/L)
- Collection page: PageFly’s custom collection layout shows one card per hoodie group with 8 swatch dots underneath
A/B testing variant strategies
PageFly has built-in A/B testing (included on all plans, no tier gating). You can test page variations with conversion tracking: add-to-cart rate, revenue per visitor, checkout rate. For stores running Rubik, the tests worth running:
- Swatch position on the PDP. Above the buy box vs below the product description vs sticky on scroll.
- Gallery layout with variant filtering. Horizontal thumbnail strip vs vertical stack vs grid. Rubik Variant Images filters the content; PageFly controls the layout around it.
- Swatch type. Color circles vs image swatches vs labeled buttons. Test which converts better for your specific product category.
- Trust element placement relative to swatches. Do trust badges above the swatch row lift conversion more than badges below?
Run each test for 2-4 weeks. PageFly tracks conversion rate and revenue per variant automatically.
Setup walkthrough
- Install PageFly. Free plan for testing (1 published page, all features).
- Install Rubik Combined Listings. Free for 5 product groups.
- Install Rubik Variant Images. Free for 1 product.
- Build your PDP in PageFly. Start from a template or build from scratch. Design the page structure: hero, buy box, descriptions, trust badges, reviews.
- Add Rubik app blocks. In the PageFly editor, find the third-party app section. Add Rubik Combined Listings to the variant picker area, Rubik Variant Images to the gallery area.
- Configure Rubik. Create product groups (RCL), assign variant images (RVI). Use AI Magic Fill for auto-color detection.
- Publish and test. Preview on desktop and mobile. Verify swatch switching and gallery filtering work correctly.
Plan variant counts with our free Shopify variant calculator. Verify swatch colors against your PageFly design using the color contrast checker.
Honest caveats
Two things to know before building your variant-heavy PDP on PageFly:
- Uninstalling PageFly deletes all PageFly-created pages. This is confirmed in merchant reviews and is worth knowing upfront. If you build 50 product pages in PageFly and later decide to switch to GemPages or Instant, your PageFly pages don’t survive the uninstall. They’re tied to the PageFly theme extension. Plan accordingly: if you’re testing, use the free plan (1 page) before committing to a full rebuild.
- No built-in sales funnels. Unlike GemPages (which has post-purchase upsell on the Optimize plan), PageFly doesn’t have a native funnel builder. If you want post-purchase cross-sell across grouped colorways, you’ll need a separate upsell app. This doesn’t affect the Rubik integration, but it’s a gap compared to our GemPages x Rubik guide.
Neither caveat is a dealbreaker. The page-deletion concern is standard for theme-extension-based page builders. The no-funnels gap is only relevant if post-purchase upsell is a priority for your store.

Pick PageFly if you want the most battle-tested page builder with the simplest pricing (no feature gating), the widest integration ecosystem (130+), and the largest community (200K+ merchants means every problem has been solved before). Pick GemPages if you need post-purchase upsell funnels. Pick Instant if your designer works in Figma. All three support Rubik app blocks identically.
“Works exactly as it should without fluff. I had an issue with my store suddenly not working anymore after redesigning my product page using Instant. I contacted Rubik CS about it, and Umid fixed the issue that had me losing my mind for a whole day in literally just a minute. Did not expect them to be so helpful. They definitely deserve their perfect 5 star rating.”

Frequently asked questions
Do both Rubik apps work inside PageFly product pages?
Yes. PageFly is one of our 7 officially supported page builders. Both Rubik Combined Listings and Rubik Variant Images render via OS 2.0 theme app blocks inside PageFly product page templates.
Do I need Shopify Plus?
No. All three apps work on every Shopify plan including Basic. PageFly free + Rubik Combined Listings free + Rubik Variant Images free = $0/month for a working prototype.
Does PageFly have A/B testing?
Yes, built-in on all plans (no tier gating). Tests page variations with conversion rate, add-to-cart rate, and revenue per visitor tracking. Use it to test swatch position, swatch type, and gallery layout on your Rubik-powered PDPs.
What happens if I uninstall PageFly?
All PageFly-created pages are deleted. This is confirmed in merchant reviews and is a real consideration. If you’ve built 50 product pages in PageFly, they don’t survive the uninstall. Test on the free plan (1 page) before committing to a full rebuild. Your Rubik configuration (product groups, variant assignments) stays intact regardless, since Rubik stores data in Shopify metafields, not in PageFly.
How does PageFly compare to GemPages for Rubik users?
Both support Rubik app blocks identically. PageFly has simpler pricing (no feature gating, $18/mo), more reviews (5,733 vs 3,621), more integrations (130+ vs 100+), and longer track record. GemPages has sales funnels with post-purchase upsell (PageFly doesn’t) and AI Image-to-Layout. Pick PageFly for proven simplicity. Pick GemPages for CRO funnels.
