In about 3.5 days, we built QR Attribution from idea to production-ready. That still feels kind of wild.
The original pain point was simple and frustrating: it was almost impossible to find a truly free QR code generator that didn’t force a signup wall, trial trap, or paywall right when you needed a basic download. Most tools wanted your email before proving value. Many charged for features that should be table stakes, like decent design control or clean exports.
So we built the tool we wanted to use ourselves.
Using Codex, we moved fast without skipping quality. We started with a simple QR generator, then rapidly layered in real-world functionality: style customization, multiple QR types, high-resolution export, tracking links, analytics, authentication, and payment rails for scaling usage. Instead of spending weeks on boilerplate or wiring glue code, we focused on user experience and iteration.
That’s the bigger shift: software is becoming bespoke again. With AI-assisted development, you don’t have to accept one-size-fits-all products anymore. If a tool doesn’t exist in the form you need, you can build it quickly, tailor it to your workflow, and ship it in days, not months.
QR Attribution is proof of that. A practical problem, a focused build, and a modern stack delivered by fast iteration with Codex.
