A free, embeddable Amazon DE listing-compliance checker (2 lines of HTML)

#webdev #javascript #showdev #ecommerce

Disclosure: I built this free tool.

If you build tools or write for Amazon Germany (Amazon.de) sellers, here's something your readers can use right on your page: a free, embeddable widget that checks an Amazon DE product listing for the issues that most often cause listing suppression — before the seller uploads.

What it checks

  • Title character limit — Amazon DE caps titles at 200 characters, and German translations overflow easily.
  • Restricted / banned terms — 22 terms that trigger suppression on Amazon DE (e.g. garantiert, bestseller).
  • Required attributes — brand, material, size, color, quantity.
  • Number / model-number / unit preservation — paste the original English text and it verifies values like AB-1200, 500 ml, 8.5 kg survived translation unchanged.

Everything runs in the visitor's browser — no sign-up, no API key, and no data leaves the page.

Embed it (two lines) 

<div id="listloco-checker"></div>
<script src="https://listloco.hayasaka.app/embed/checker.js"></script>
Enter fullscreen mode Exit fullscreen mode

The script injects scoped CSS (every class prefixed llc-), renders only inside that one mount element, makes zero network requests, sets no cookies, and collects no PII. It shows a small "Powered by ListLoco" link you can remove if your site policy requires.

Live demo + copy-paste snippet: listloco.hayasaka.app/embed
Standalone tool (no embed): listloco.hayasaka.app/tools/amazon-de-listing-checker

Prefer code?

The same rules engine is on npm (MIT, zero dependencies):

npm i listloco-checker
Enter fullscreen mode Exit fullscreen mode 
import { check, amazonDeRules } from "listloco-checker";

const result = check(
  {
    title: "Kabellose Bohrmaschine AB-1200 garantiert bester Preis",
    brand: "Bosch",
  },
  amazonDeRules,
);

result.pass;        // false — "garantiert" is a restricted term
result.violations;  // the specific failures (restricted term, missing attributes)
Enter fullscreen mode Exit fullscreen mode

Need full EN→DE localization?

The widget detects compliance issues in existing text. If you need the full pipeline — English→German translation with model-number/unit preservation, glossary enforcement, and a back-translation quality gate in a single POST — there's a hosted API on RapidAPI (linked from the site).

Built for Amazon DE sellers expanding from English catalogs. Feedback and edge cases welcome in the comments.
