API & Developer Tools

QR Barcode Maker is built on top of open-source libraries and runs 100% in the browser — no backend, no rate limits, no API keys. If you want to embed the same generation power in your own app, you have two paths: use the underlying open-source libraries directly, or open our generator with prefilled URL parameters.

Path 1 — Use the Same Open-Source Libraries

Our entire stack is open-source and self-hostable. You can build the same generators into your own product:

QR codes — qr-code-styling (MIT)
Barcodes — JsBarcode (MIT)
ZIP packaging — JSZip (MIT/GPL)
File download — FileSaver.js (MIT)

Minimal QR example

<script src="https://unpkg.com/qr-code-styling@1.6.0-rc.1/lib/qr-code-styling.js"></script>
<div id="qr"></div>
<script>
  const qr = new QRCodeStyling({
    width: 400, height: 400,
    data: "https://example.com",
    dotsOptions: { color: "#2563EB", type: "rounded" },
    backgroundOptions: { color: "#FFFFFF" }
  });
  qr.append(document.getElementById("qr"));
</script>

Minimal Barcode example

<script src="https://cdn.jsdelivr.net/npm/jsbarcode@3.11.6/dist/JsBarcode.all.min.js"></script>
<svg id="barcode"></svg>
<script>
  JsBarcode("#barcode", "1234567890128", {
    format: "EAN13",
    width: 2,
    height: 100
  });
</script>

Path 2 — Deep Link Into Our Generator

Open our generator with prefilled values via URL query parameters. Perfect for "create a QR" buttons in your app:

Why No Hosted API?

We deliberately do not run a paid hosted API. Reasons:

Privacy. A hosted API means we see every URL you encode. We do not want that responsibility, and you should not give it to us.
Cost. Hosted APIs justify their existence by charging. We are committed to free.
Speed. The libraries above generate codes in <5ms. A network round-trip is slower.
Resilience. No external dependency on our uptime; your code keeps working forever.

Future Plans

We are exploring a fully open-source companion library — a single bundle that wraps all generators behind a clean JavaScript API and weighs under 50 KB gzipped. If that interests you, follow our GitHub repo for updates.
