Scrolly Review (2026)
E-commerce tooling is ROI-math on margin: every tool must pay for itself in conversion, basket size or saved hours. So where does Scrolly actually fit?

What Scrolly does
Free Shopify app from Effectify that adds a customizable floating back-to-top button and, optionally, infinite scroll on collection pages, with no code and no paid tier. The button is a safe convenience; the infinite scroll replaces the paginated collection URLs crawlers use, so it is a merchandising decision rather than a styling one.
Pricing (2026)
✓ Pricing re-verified 25 Aug 2026
(read 2026-08-25 on apps.shopify.com/custom-scroll-to-top) Free, and free is the only plan. The listing carries no paid tier, no usage meter and no Shopify-plan surcharge — the pricing block that most App Store listings use to sell an upgrade is simply absent here. The app has been on the App Store since March 2020 and carries Shopify's Built for Shopify badge, which is the store's own bar for performance, design and integration. Plans change — always verify the live price on their site.
The honest knock
The two features carry very different risk and the app presents them as one install. Infinite scroll replaces the paginated collection URLs a crawler uses to walk a large catalogue, pushes your footer permanently out of reach, and on some themes collides with the load-more or filtering logic already in the theme — that is a merchandising decision, not a styling toggle. The app also edits Online Store script tags and the theme, so it adds a third-party script to every page and an uninstall can leave remnants.
And because there is no paid tier, there is no support contract behind it either: what you get is the vendor's goodwill, which the six-year run on the App Store suggests is real, but it is not something you can buy more of when you need it.
There is no premium, so the decision is which of the two features you switch on
There is nothing to buy here, which removes the usual question and leaves a better one. Scrolly does two separate things, and they carry very different risk.
The back-to-top button is the low-risk half. It is a floating control with the styling you would expect to pay for — colour, shape, size, hover colour, position, horizontal and vertical padding, animation — and you can scope it to the whole store or to specific pages. On a long collection or a long product page it is a small, genuine convenience, and if you dislike it you turn it off and nothing about your store has changed.
Infinite scroll is the half that deserves a decision. Loading more products as the shopper scrolls replaces the paginated collection URLs underneath, and those paginated URLs are how a crawler walks a large catalogue. It also puts your footer out of reach, because the page keeps growing beneath it, and on some themes it interferes with the load-more or filtering logic the theme already ships. None of that makes it wrong — plenty of stores run it deliberately — but it is a merchandising and SEO choice dressed up as a display setting, and it should be made on purpose.
One cost applies either way. The listing's data-access panel says the app edits Online Store script tags and the theme, so switching it on adds a third-party script to your storefront and switching it off can leave remnants behind. The Built for Shopify badge means it cleared Shopify's own performance review, which is a real counterweight, but it is still one more thing running on every page.
How to actually use Scrolly
Turn the button on and leave infinite scroll off for the first week. The two features are independent, they carry completely different risk, and shipping both at once means you will not know which one caused whatever you see afterwards.
If you then want infinite scroll, enable it on one collection rather than the whole store. Two things are worth watching after that: whether Search Console keeps crawling the paginated collection URLs for that collection, and whether products viewed per session actually rises in your analytics. Infinite scroll is sold on the second number, and it is the one merchants almost never check.
Because it writes script tags into the theme, note the date you installed it. If you later uninstall and something odd persists in the storefront, that date is where you start looking, and the vendor's help centre at effectify.help documents the settings.

Frequently asked questions
Does Scrolly work with my store platform?
Check your platform and version specifically. Shopify support is close to universal in this category, while WooCommerce, BigCommerce, Magento and headless setups vary a lot, and 'supported' sometimes means a generic API rather than a maintained app. A listing in your own platform's app store, with recent reviews there, is a better signal than the vendor's logo wall.
Who should not use Scrolly?
Skip it if you run a large catalogue that depends on paginated collection URLs being crawled, your theme already ships its own load-more or filtering behaviour, or you need conversion work rather than navigation polish — this only changes how the page scrolls. Buying a tool to fix a problem you don't have yet just adds cost and another login to manage.
