Best Shopify Page Builders: Shogun vs PageFly vs GemPages

Page builders solve a real problem. Your marketing team wants to launch a campaign landing page on Thursday, your theme does not have the layout they need, and a developer is not available. A page builder lets them drag something together and publish it.

That is a legitimate need and these tools meet it. But page builders are also, in my experience auditing Shopify stores, one of the two or three most common causes of serious performance problems — and the reason is structural rather than a fault of any particular app. So before comparing them, it is worth understanding what you are trading.

What a page builder actually does to your store

A Shopify theme renders pages server-side from Liquid templates. The output is relatively lean because the structure is fixed and the platform generates it.

A page builder inserts a layer on top. It loads its own scripts and stylesheets, renders content through its own system, and gives you free-form positioning that the theme’s section architecture does not. That layer has weight, and it loads on every page built with it.

The consequence is that page-builder pages are typically heavier than equivalent theme sections. Sometimes considerably. And because page builders are most often used for landing pages and campaign pages — precisely the pages you drive paid traffic to — the performance cost lands on your most expensive visitors.

None of that makes them wrong to use. It makes the trade worth understanding: you are buying marketing autonomy and paying for it in page weight.

The alternative most stores have not tried

Here is the part that changes the decision for a lot of brands.

Online Store 2.0 gave Shopify themes a proper section architecture. Sections can be added, reordered, and configured on any page through the theme editor, with settings you define. A well-built section library means your marketing team can compose landing pages from branded, tested, fast components — without a page builder and without a developer.

Most stores that install a page builder have never had a section library built for them. They are comparing “page builder” against “the handful of generic sections my theme shipped with,” which is not the real alternative.

A custom section library built for your brand — hero variants, feature blocks, testimonial layouts, comparison tables, FAQ blocks, whatever your campaigns actually need — gives marketers the same autonomy with none of the weight, because the output is native theme code.

That is an upfront investment rather than a monthly subscription, and for stores running frequent campaigns it usually pays back quickly in both performance and consistency. It is worth pricing before defaulting to a builder.

Where the main options sit

Verify current details before publishing; this market moves.

PageFly is the most widely used and generally the most accessible. Large template library, approachable editor, competitive pricing, and a free tier that lets you evaluate properly. For a small team wanting to build campaign pages without much fuss, it is the common landing point.

Shogun positions itself further up-market, with a stronger emphasis on optimisation and testing, analytics on page performance, and features aimed at teams treating landing pages as a conversion discipline rather than a publishing task. Priced accordingly.

GemPages competes closely with PageFly on ease and templates, with its own editor approach and a strong template selection. Worth trialling alongside PageFly since preferences between the two are often down to which editor feels better to the person using it daily.

Other options exist and the category is competitive. The differences between the mainstream tools are smaller than their marketing suggests; the differences in how heavy your resulting pages are depend as much on how you use them as on which you chose.

How to choose between them

Trial the editor with the person who will actually use it. This matters more than feature lists. Page builders are used daily by marketers, and an editor that feels intuitive to your team will produce more and better pages than a theoretically superior one they find frustrating. Build the same landing page in two tools and see which takes less time.

Check the output weight, not the feature list. Build a representative page in each trial, publish it, and run it through PageSpeed Insights on mobile. The difference between tools is real and it is the thing least likely to appear in a comparison article.

Check what happens when you uninstall. This is the question people forget. Pages built with a page builder frequently break or revert when the app is removed, because the rendering depends on the app. Find out exactly what you would be left with, because it determines how locked in you are.

Check the template library against your actual needs. Templates save enormous time if they suit your brand and are useless if they all look like someone else’s store.

Consider who maintains brand consistency. Free-form builders make it easy to produce pages that drift off-brand. Some teams want that freedom; others need guardrails.

The performance discipline

If you use a page builder, these habits keep the cost manageable.

Use it for landing pages, not your whole store. Your product pages, collection pages, and homepage should be native theme templates. Reserve the builder for campaign pages where the flexibility earns its weight.

Do not run two page builders. It happens more often than you would think — someone trials a second one and the first never gets removed. Now every page carries both layers.

Optimise images inside builder pages properly. Builders make it easy to drop in a full-resolution hero image, and they will not stop you.

Measure the pages you build. Landing pages receiving paid traffic should be checked in PageSpeed Insights as a matter of routine, because a slow landing page wastes ad spend at the exact moment it is most expensive.

Audit periodically. Old campaign pages accumulate, and unused pages built on an app you are paying for are pure cost.

A worked example: replacing the builder

A supplements brand came to us for speed work. Their homepage and product pages were reasonable; their landing pages — where all their paid traffic went — were dreadful, and conversion on paid campaigns had been sliding.

The diagnosis was straightforward. Every landing page was built in a page builder, loading the builder’s scripts and stylesheets on top of the theme’s, with hero images dropped in at full resolution. Mobile load times on those pages were roughly double the rest of the site.

They had installed the builder for a good reason: their theme had five generic sections and their marketing team needed more. The builder was solving a real problem.

We built them a section library instead — twelve branded sections covering the layouts their campaigns actually used, configurable in the theme editor, with image handling done properly. The marketing team kept their autonomy. The builder was removed.

Landing page load times came down to match the rest of the site, paid conversion recovered, and they stopped paying a monthly subscription. The section library cost more upfront than a year of the app, and it was a better investment because it removed the weight rather than managing it.

That is not the right answer for everyone. A store running occasional campaigns with no budget for custom sections is better served by a page builder than by nothing. But if you are spending meaningfully on paid traffic, the arithmetic usually favours native sections.

When a page builder is the right call

To be fair, because the answer is not always “build sections.”

You need pages now and have no development budget. A builder gets you moving today.

Your campaign layouts vary wildly and unpredictably. If every campaign needs a different structure, a fixed section library may not cover it.

You are testing concepts rather than committing. Builders are good for experimentation before you know which layouts you actually need. Several brands use a builder to discover their patterns, then build those patterns as sections.

Your volume is low enough that the weight does not matter much. A store with modest traffic and little paid spend has less to lose.

Nobody on your team can brief a developer. Sometimes autonomy is worth the trade regardless.

Side by side

Verify current pricing and feature specifics against each vendor before publishing.

What to build in a section library

If you are weighing the custom route, it helps to know what “a section library” actually means in practice. For most brands, twelve to twenty well-built sections cover nearly every campaign layout they will ever need.

Hero variants — full-bleed image, split image and text, video background, text-only with a strong statement. Three or four covers most campaigns.

Feature and benefit blocks — icon grids, alternating image-and-text rows, numbered steps.

Social proof — testimonial carousels, review highlights, logo strips, customer photo grids.

Product display — featured product blocks, collection rows, comparison tables for ranges.

Conversion elements — email capture, countdown or launch blocks, FAQ accordions, trust-signal rows.

Editorial — rich text with imagery, quote blocks, before-and-after layouts.

Each is built once, styled to your brand, made responsive properly, and given configurable settings so marketers can change copy, imagery, colours, and ordering without touching code. The library grows as new needs appear, which is a small piece of work each time rather than a rebuild.

The reason this beats a builder for campaign-heavy brands is not only performance. It is that every page your team assembles is automatically on-brand and mobile-correct, because those decisions were made once at the component level rather than being re-made by whoever is building the page at five o’clock on a Thursday.

Landing pages and paid traffic: why the weight matters most here

There is a particular irony in how page builders get used, and it is worth spelling out because it changes the cost calculation.

The pages most often built with a builder are campaign landing pages. Those are also the pages receiving your most expensive traffic — paid search, paid social, influencer links — where every visitor has a direct acquisition cost attached.

So the performance penalty lands precisely where it is most expensive. A slow organic blog post costs you a reader. A slow landing page costs you a visitor you paid for, and it does so at scale across a campaign.

The arithmetic is unforgiving. If a builder-built landing page loads a second or two slower than a native one, and that costs even a small percentage of conversions, multiply it across a campaign’s traffic volume and compare it to the app’s monthly fee. For brands spending seriously on acquisition, the performance cost routinely exceeds the subscription several times over — and it never appears as a line item, which is why it goes unnoticed for years.

The practical response is not necessarily to abandon the builder. It is to measure your landing pages as a standard part of campaign setup, the same way you would check the tracking is firing. If a page is slow, fix it before the spend starts rather than discovering it in the post-campaign analysis.

Common mistakes with page builders

Building the whole store in one. Product pages, collection pages, and the homepage should be native theme templates. Builders are for campaign pages. Stores that build everything in a builder carry the weight on every single visit.

Leaving a trial installed. Someone evaluates a second builder, decides against it, and never uninstalls. Now both layers load. This is more common than it sounds and worth checking today.

Dropping in full-resolution images. Builders will happily let you place a five-megabyte hero image. Nothing stops you, and nothing warns you.

Never auditing old pages. Campaign pages accumulate. Pages from campaigns that ended two years ago still exist, still get crawled, and still justify a subscription nobody has questioned.

Copying a template without adapting it. Templates are a starting point. Published unedited, they make your brand look like every other store using the same app.

Assuming the pages are yours. Until you have tested what happens on uninstall, treat every builder page as rented rather than owned.

The bottom line

Page builders solve a real problem and the mainstream options — PageFly, Shogun, GemPages — are all capable. Choose between them by trialling the editor with the person who will use it, checking the output weight of a real page, and finding out what happens if you uninstall.

But test the alternative first. A properly built section library gives your marketing team the same independence with native performance and enforced brand consistency, and for any store spending real money on paid traffic it usually pays back faster than the subscription it replaces. Most brands that install a page builder have never seen what a good theme build can do, because they are comparing against the generic sections their theme happened to ship with.

If you do use a builder, contain it: landing pages only, one builder, images handled properly, and pages measured on mobile as a matter of routine. Used that way it is a useful tool. Used to build your whole store, it is one of the most reliable ways to end up with a slow one.

Frequently asked questions

Can I move from a page builder to native theme sections later?

Yes, and it is a common and sensible progression. Many brands use a builder early to discover which layouts their campaigns actually need, then have those specific patterns built as native sections once the requirements are clear. That sequence is better than guessing at a section library upfront, because you build what you have proven you use rather than what you imagined you would. The migration is page-by-page rather than all at once: build the sections, rebuild your highest-traffic landing pages natively first, verify the performance improvement, then work through the rest and remove the app. Keep the builder installed until every page you care about has been rebuilt, since uninstalling early can break pages still in use.

Do Shopify page builders slow down your store?

Generally yes, and the reason is structural rather than a fault of any specific app. A page builder inserts a rendering layer above your theme, loading its own scripts and stylesheets on every page built with it, so those pages are typically heavier than equivalent native theme sections. The problem compounds because builders are most often used for landing pages — exactly where you send paid traffic — so the performance cost lands on your most expensive visitors. It is manageable with discipline: use the builder only for campaign pages, never run two, handle images properly, and measure the pages you build on mobile.

Which Shopify page builder is best?

The mainstream options are closer than their marketing suggests. PageFly is the most widely used and most accessible, with a large template library and a free tier for evaluation. Shogun sits further up-market with stronger optimisation and testing features for teams treating landing pages as a conversion discipline. GemPages competes closely with PageFly on ease and templates. Rather than choosing on features, trial two with the person who will actually use the tool daily — build the same page in each and see which is faster to work in — then check the output weight of the published page in PageSpeed Insights.

What happens to my pages if I uninstall a page builder?

Often they break or revert, which is why you should establish this before committing rather than after. Because the builder renders the page through its own system, removing the app can leave pages blank, broken, or stripped back to raw content. Some tools handle this better than others, and some let you export or publish to native code. Ask the vendor directly what you would be left with and test it on a trial page. This single question determines how locked in you are, and it is the most commonly overlooked part of the decision.

Is a custom section library better than a page builder?

For stores running frequent campaigns or spending meaningfully on paid traffic, usually yes. A section library built for your brand gives marketers the same drag-and-reorder autonomy through Shopify’s native theme editor, but the output is native theme code — so pages are fast, consistently on-brand, and carry no app subscription or uninstall risk. It costs more upfront than a monthly app and typically pays back through performance and removed subscriptions. A page builder remains the better choice when you need pages immediately, have no development budget, or are still discovering which layouts your campaigns actually need.
