QKQR is built using a client-side only architecture with the following technologies:

• HTML5: Structure and content
• CSS3: Styling and animations
• JavaScript: Core functionality and interactivity
• Canvas API: For rendering and exporting QR codes as PNG images
• WebGL: Used for background shader effects on the 404 page
• Web Share API: For sharing QR codes (on supported browsers)

QKQR uses the following libraries and APIs:

• QRCode.js (v1.0.0): Primary QR code generation library
• QRCode-SVG (v1.1.0): For generating vector-based QR codes
• Phosphor Icons: For UI icons
• Google Fonts API: For typography (Inter and Press Start 2P fonts)
• Google Maps Search API: For location QR codes

Open the index.html file in a modern web browser to generate QR codes. No installation, server setup, or build process is required. Everything is client side, no data is collected or stored anywhere, ever!

• Google Chrome (recommended)
