Almost nothing in this category lends anybody money. These are messaging widgets: they put a line on your product page saying an item could be paid for in four parts, and one of them states in capital letters on its own listing that it does not process transactions. The finance itself is arranged elsewhere entirely.

Elsewhere means your payment settings. Instalment providers are switched on as payment methods inside Shopify Payments rather than installed from the App Store, and Shopify's own instalment product already displays promotional banners on product and cart pages without any app at all. So the question is not which of these to buy but whether you have a gap: a provider that is genuinely live at checkout, whose availability shoppers are not being told about early enough to matter.

What to look for in a Klarna app

Whether it can advertise something you do not actually offer: This is the real risk in the category. A widget that renders whatever you configure will happily promise instalments that vanish at checkout, and the customer discovers it at the worst possible moment. Prefer one that reads which providers are genuinely active rather than one you fill in by hand.
Check what you already display: If you use Shopify's own instalment product, promotional messaging comes with it. Look at your product page as a customer before assuming there is nothing there, because the most common outcome of installing one of these is two messages saying roughly the same thing in different fonts.
Eligibility is not universal: Instalment offers carry order-value floors and ceilings and are limited by region, so a widget on every product will be wrong on some of them. Ask whether it respects those thresholds, or whether you are advertising a payment option that will not appear for a basket that is too small or too large.

What does the Built for Shopify badge mean?

Built for Shopify
Built for Shopify is the highest level of recognition Shopify awards an app. To earn the badge, an app must meet Shopify's standards for safety, performance, ease of use, and proven usefulness: it cannot slow down the admin, storefront, or checkout, must integrate seamlessly into the Shopify admin, and must demonstrate quality through installs, reviews, and ratings over time. When comparing similar apps, preferring ones with the badge is a safe default. Learn more about the Built for Shopify badge →

Rankbase is made by Craftshift, a Shopify Partner building apps for product images, variants, and bulk catalog work. We built Rankbase to track the App Store rankings of our own apps first, then opened it to other developers, and this directory grew out of that work. The rankings on these pages are Shopify's own organic search results; we never edit them, including for our own apps.
