Qr Code Generator App Offline

Builds a complete QR code generator as a single index.html file. Create QR codes for links, text, Wi-Fi, contacts, email and phone numbers, with custom colors, size, margin, error correction and an optional center logo. Download as PNG or SVG. The QR encoder is written from scratch, so it runs fully offline with no libraries or signup. Change [APP NAME] and [COLOR THEME] to brand it your way. Works with Claude Code. Tested with Sonnet 5.5.
