100% client-side, no backend, no uploads. Built with React, JSZip, and Canvas.
We just launched the RahaLune Bulk QR Generator — a tool that generates up to 500 QR codes at once, entirely in the browser.
Here's why we built it and what we learned.
The Problem
Most QR generators create one code at a time. For anyone who needs more than 10 (event organizers, retailers, marketers), this is a nightmare.
We wanted to remove that friction entirely.
What It Does
Upload a CSV file, paste a list, or add items manually. Customize the design once. Generate up to 500 QR codes.
Download as:
- ZIP file with PNGs
- ZIP file with JPGs
- Print sheet PDF
Each QR code can have:
- Unique content (URL, text, WiFi, vCard)
- Custom filename
- Unified styling (colors, logo, pattern)
