The source-code fingerprint

js.klarna.com Search all 17,944 results →

Klarna's Web SDK and On-Site Messaging load from js.klarna.com, so the hostname appears on storefronts offering Klarna at checkout or promoting installments.

Likely false positives: Redirect-based Klarna checkouts never touch the storefront's HTML, so this undercounts total Klarna merchants.

Example websites using Klarna

These domains all contain the js.klarna.com fingerprint in their homepage source right now. A match is a verified substring of the live page, so confidence is high, the false positives noted above are the main caveat.

How this works

SearchWebCode indexes the raw HTML, CSS and JavaScript source of public web pages. To find sites using Klarna we match the literal fingerprint js.klarna.com, the code Klarna ships, against that index, then verify each match against the raw source. Counts reflect the current index (129,313,463 domains, refreshed monthly, last built August 2026) and grow as we scale toward the whole web. Run the search yourself to see every match, view the full page source for any result, filter by TLD or regex, and export the domain list.
