Not all QR codes are created equal. A beautiful design can still fail to scan if the contrast is too low or the logo covers too much of the data. We built the RahaLune QR Code Debugger to remove the guesswork. Upload any QR image, and our tool runs 6 standardized optical tests to analyze contrast, white space, print quality, and error recovery. You get an instant, actionable report giving you a 0-100 scannability score. It's 100% free, ad-free, and completely client-side (your images never touch a server).
