Why client-side?

Generating QR codes entirely in the browser provides several advantages:
Your sensitive data (WiFi passwords, payment details, contact info) never leaves your device. No server storage means no data breaches or privacy concerns.
QR codes generate instantly without network roundtrips. Works perfectly offline once the page is loaded.
Static site deployment is cheap or free. No backend infrastructure, databases, or server maintenance required.
Open source code means you can verify exactly what happens with your data. No hidden tracking or analytics.
