QRU? - QR Code Debugger
Scan & Decode URL Components
Free · Designed for iPad
A developer's QR code debugger. Colorized URL breakdowns, scan history, and QR generation. Always free, no ads, open source.
QRU? is a free, open-source QR code debugger built for developers. Scan any QR code and instantly see its data broken down into color-coded components.
Stop guessing what's inside a QR code. QRU? scans and parses QR codes, then displays a colorized breakdown of every URL component — protocol, host, path, and query parameters — each in a distinct color so you can debug at a glance.
