Dynamic QR codes that tell you if they'll actually scan
Every QR generator lets you pick a pretty color. None tell you the code won't scan. nwnay scores your code server-side on contrast and density. Pick our own brand pink and it drops to 34/100 with a plain warning. Pick black and it's 96. You see that before the print shop does. The code encodes a short link, never the destination — so a printed poster can point somewhere new, forever, without reprinting. 33 destination types. Scans counted by hour, city and country. The IP is never stored.
Hi PH 👋
I built this after watching a bar owner tape a new sign over an old one because the QR on it pointed to a menu that no longer existed.
Dynamic QR codes aren't new. What surprised me while building it is that almost nobody checks the other half of the problem: whether the code actually scans. Every generator happily hands you a pastel QR on a white background. I ran ours through the renderer and measured it — our own brand pink scores 34/100, contrast 2.2:1. So I left it in the color picker and made the score drop in front of you instead of hiding it. The tool that sells you a code should be the one that warns you.
Honest about where it is: it launched days ago, there are no customers yet, and the whole site is in Spanish (rioplatense — I'm not going to pretend otherwise). The free tier is 3 codes and 1,000 scans, no card.
Happy to answer anything, especially about the scannability scoring.
