Status: Built Open source
QRGen: a QR studio without paywalls
An open-source QR code generator that runs entirely in the browser: styling and logo embedding without watermarks, accounts, or ads.
- Vue 3
- TypeScript
- Vite
- Tailwind CSS
- DaisyUI
- qr-code-styling
Context
Most free QR generators watermark downloads, cap resolution, hide styling behind subscriptions, or send what you encode to a server.
My role
Product, design, and engineering, solo.
What I built and decided
- Client-side generation, so URLs and text never leave the browser.
- A live preview with dot, finder-eye, and gradient styling.
- Logo upload with an in-place cropper for clean centre placement.
- High-resolution PNG export without watermarks.
Outcome
A free, MIT-licensed tool whose privacy claim can be checked in the source code.
What I'd do next
Add automated scan tests, so styling options that hurt scannability are caught before release.
