Most Shopify merchants hit the same wall: they want a store that looks more custom, converts better, and stays easy to manage, but they do not want to touch theme code or turn their storefront into a slow, fragile mess. That is exactly why Store Design apps exist. The best ones help you add sections, redesign landing pages, improve merchandising, and create a more polished brand experience without rebuilding your theme from scratch.
The tricky part is that not all design apps solve the same problem. Some are section libraries that extend your theme cleanly. Others are full page builders that give you more layout freedom but can add complexity. A few are best when design overlaps with merchandising, like product personalization or B2B storefront workflows. If you are comparing options, the right question is not just "which app has the most features?" but which app matches how your team actually works.
The best Shopify Store Design apps right now
Here is a fair shortlist of strong options, with an honest take on where each one shines and who it suits best.
- Sectionly: Section Library — Best for merchants who want to add high-converting sections fast without editing theme code; especially strong for lean teams on Online Store 2.0 themes.
- PageFly Landing Page Builder — Best for marketers who need highly custom landing pages and campaign control; better for teams willing to trade simplicity for flexibility.
- Shogun Page Builder — Best for larger brands that want structured visual editing and testing workflows; usually a stronger fit for teams with bigger budgets.
- GemPages Landing Page Builder — Best for merchants focused on conversion-oriented page design with lots of templates; can be a strong middle ground between usability and freedom.
- EComposer Landing Page Builder — Best for merchants who want wide template choice and all-in-one page building; good value, though feature depth can feel heavier than needed.
- LayoutHub Easy Page Builder — Best for smaller stores that want polished prebuilt layouts quickly; less ideal if you need highly bespoke control.
- Section Store — Best for merchants who specifically want to buy individual theme sections à la carte; useful for simple needs, though ongoing editing experience depends more on your theme setup.
What to look for in a Store Design app
The biggest decision is whether you need theme-safe sections or a full visual page builder. That sounds small, but it changes day-to-day maintenance, performance, and how much your team depends on outside help.
If your goal is to improve an existing theme with better blocks like hero banners, announcement bars, FAQs, trust badges, testimonials, and product feature sections, a section-first app is often the cleaner choice. This is where Sectionly makes a clear case: its model is built around adding or removing sections in a few clicks, with one-click install, compatibility with any Online Store 2.0 theme, and no developer required for routine design changes. For many merchants, that is enough to raise conversion and improve the storefront without taking on the overhead of a full page-builder stack.
What you should evaluate:
- Ease of maintenance: Will your team still understand the storefront six months from now?
- Theme compatibility: Does it work cleanly with your current Online Store 2.0 setup?
- Performance impact: Does the app add unnecessary scripts or duplicate layout logic?
- Design flexibility: Do you need custom landing pages, or just better sections within your theme?
- Team workflow: Can marketers make updates without a developer bottleneck?
If you are mainly refining your current storefront rather than creating dozens of custom pages, a section library will often be the more sustainable path. If you are running aggressive campaign landing pages or want full visual control over each layout, a page builder may be worth the extra complexity.
The real tradeoffs between Sectionly and page builders
This is where buyers should be honest with themselves. Sectionly: Section Library is not trying to replace every page builder, and that is part of its appeal. It is strongest when you want to keep your theme clean, fast, and manageable while still adding more conversion-focused content blocks. That suits brands that value simplicity, speed, and fewer moving parts.
By contrast, tools like PageFly, Shogun, GemPages, and EComposer are often stronger when you need:
- Custom campaign landing pages
- More freeform layout control
- Rich template ecosystems
- Design workflows that live outside the native theme structure
The tradeoff is that page builders can introduce more design surface area to manage. For some merchants that is a feature; for others, it becomes technical debt. A founder-led brand or small ecommerce team often does not need unlimited layout control. They need dependable tools that help them ship better pages faster. That is why Sectionly is especially compelling for merchants browsing solutions or comparing practical alternatives: it solves a narrower problem very well.
There is also a second layer to store design that many merchants overlook: the product page and buyer flow are part of design too. If your storefront needs product customization, file uploads, or personalization, then design alone will not solve it. In that case, Sectionly's related apps may be more relevant, especially if you are working through custom options, file upload, or broader product personalization. Likewise, B2B sellers who need to hide prices or replace checkout with quote capture may care more about storefront function than page layout, which is where guides on hide price and request a quote become more useful than another design template.
How to choose the right app for your store
A simple way to choose is to start with the job you need done.
Choose Sectionly: Section Library if:
- You already like your theme and want to improve it, not replace it
- You want new sections installed quickly without editing code
- You care about keeping your store fast and easy to maintain
- Your team wants a no-code workflow inside a familiar Shopify setup
Choose a page builder like PageFly, GemPages, Shogun, or EComposer if:
- You need more bespoke landing pages for campaigns or launches
- Your design team wants more visual freedom than theme sections allow
- You are comfortable managing a more complex storefront stack
Choose LayoutHub or Section Store if:
- You want prebuilt layouts or single sections with minimal setup
- Your needs are narrower and you do not want a larger toolset
For most merchants, the safest path is to solve the smallest real problem first. If your store just needs stronger homepage sections, better social proof blocks, or cleaner product storytelling, a theme-safe section app is usually the highest-leverage move. If you later outgrow that, then a full page builder becomes easier to justify.
Bottom line
The best Store Design app is the one that improves conversion without making your storefront harder to run. Sectionly deserves to be near the top because it offers a very practical balance: a library of conversion-focused sections, quick installation, no theme-code editing, and compatibility with Online Store 2.0 themes. That will not make it the best tool for every merchant, but it does make it one of the most sensible options for brands that want cleaner design upgrades with less risk.
If you need maximum layout freedom, competitors like PageFly, Shogun, GemPages, and EComposer are genuinely strong choices. If you want the fastest path to a better-looking store that stays lightweight and maintainable, Sectionly is the option many merchants should try first.
