A beautiful, fully client-side QR code generator with advanced design customization. No data ever leaves your browser.
Completely vibe coded by Boshe during NSND 2026 at Base42. Zero humans were harmed in the writing of this code. Several were mildly confused by it.
Vibe checks pass, good enough.

This project was born at Base42's Nothing is Going to Happen (Nista se nece dogoditi) hackathon. The rules said no hardware tools - they didn't say anything about letting an AI write your entire app while you supervise with a coffee in hand. Is it cheating? We prefer "creative interpretation of the rules." The QR codes work. The code... also works. We checked. Once.
PRs welcome, but honestly the AI might rewrite your contribution before you finish your commit message. If you find a bug, that's a feature we haven't documented yet.
