QR Code Agent

A free QR code generator with logo support — no sign-up, no watermark, no expiry.

→ qrcodeagent.net

Every code is generated entirely in your browser. Nothing you type is uploaded, no account is created, and no scans are tracked. Download a PNG for screens or a true-vector SVG for print.

What it makes

URL · WiFi · vCard contact · WhatsApp · restaurant menu · PDF · Google review · Instagram · Facebook · YouTube · Spotify · app download · event · phone · SMS · plain text · Bitcoin

Style the dots and finder patterns, set your own colours, and drop a logo in the middle — with error correction raised automatically so the code still scans.

Honest limitations

• The codes are static. The destination is encoded into the pattern itself, so it cannot be edited after you download it — and it also cannot stop working when some service shuts down or starts charging. That is the trade.
• No scan analytics, for the same reason. Tracking would require routing every scan through a server, which is exactly what this tool avoids.
• A logo in an SVG export stays raster (you supply a PNG); the QR pattern itself is true vector.

If you need editable destinations or scan counts, you need a dynamic QR product — this is not one, and /learn/static-vs-dynamic-qr-codes explains the difference.

For developers

Astro (static output) + React islands, deployed on Vercel. The site is 47 pages rendered as unique static HTML, currently live in 3 of 11 declared locales (en, de, es) for 141 URLs. Encoding uses qrcode-generator.

npm install
npm run dev        # http://localhost:4321
npm run verify     # tests + build + dist checks — run before every push
npm run test:e2e   # Playwright: boots dist/ and proves the generator hydrates

Layout

Path	What it is
src/content/pages.json	Content source of truth — site config + all 47 pages
src/content/i18n/<loc>.json	Per-locale translation bundles (a locale goes live by existing)
src/lib/qr.js	Pure QR logic — encoder, styling, SVG export. Testable, never forked into the component
src/lib/content.js	hreflang alternates, JSON-LD graph, LIVE_LOCALES
src/components/Generator.jsx	The widget (React island)
src/pages/[...slug].astro	One static route per page
scripts/check-build.mjs	Post-build verification of dist/

Two rules that have bitten before

1. After changing Generator.jsx or lib/qr.js, load a page in a real browser. A green build and a green unit suite once shipped a hydration crash that took the generator off every page — Astro never evaluates the island at build time.
2. Never merge a partial locale bundle. Missing slugs silently serve English content under a locale prefix while hreflang claims otherwise. npm run i18n:merge enforces this; do not bypass it.
