A fast and easy tool to generate custom barcodes and QR codes with live preview and high-quality downloads.
From idea to deployment, here’s how we built our QR Code Generator into a reliable, customizable, and easy-to-use platform that helps users create QR codes for links, Wi-Fi, business cards, and more.
Identified the growing need for a simple yet powerful QR code generator. Researched user demands such as URLs, Wi-Fi, vCards, and social media QR codes.
Defined core features like customization, high-resolution downloads, and multi-language support. Planned for a clean, intuitive UI to make QR creation effortless.
Developed the platform using Next.js, Tailwind CSS, and TypeScript with a focus on speed, responsive design, and SEO optimization.
Deployed on VPS Server for scalability, integrated analytics to monitor QR scans and usage trends, and optimized performance for global users.
A fast and easy tool to generate custom barcodes and QR codes with live preview and high-quality downloads.
Barcode & QR Code Generator is a lightweight web application that allows users to create, customize, and download professional-quality barcodes and QR codes instantly. Built with Next.js and React, it offers real-time previews, multiple export formats, and a simple user experience for businesses, marketers, and personal use.
Existing generators were cluttered, slow, and locked common formats behind paywalls. The client needed a tool fast enough to feel instant, simple enough for non-technical users, and flexible enough to export at print quality.
We scoped a minimal interaction model: pick a format, type or paste content, see the code update live. Generation runs client-side where possible, with Supabase handling saved presets and usage analytics through a typed tRPC layer.
The tool now serves 50k+ monthly active users with sub-second generation and a 4.9/5 average rating, with zero paywalls on core formats.
