Inspiration

QR codes are everywhere, but most tools today are either too basic, unreliable, or lack analytics. I built QR Nexus to bridge that gap: a powerful, secure platform that makes QR codes trackable, customizable, and insightful.

What it does

QR Nexus lets users generate high-quality, customizable QR codes, track real-time analytics, and verify the safety of each QR-linked URL using Google Safe Browsing, Perplexity, and other security-based APIs. From branded design to secure redirection and scan performance insights, it’s the all-in-one platform for professional QR code management.

How we built it

I used Bolt.new utilizing React, TypeScript, and Tailwind CSS for a modern frontend experience, backed by Supabase for authentication, data storage, and real-time subscriptions, deployed with Netlify and using a custom domain from Entri. The platform also integrates Google Safe Browsing and uses serverless functions to log and analyze scans.

Challenges we ran into

Handling real-time analytics while preserving privacy required careful database design and RLS rules. I also faced challenges around optimizing QR rendering, improving mobile scan tracking, and ensuring reliable security checks.

Accomplishments that we're proud of

I'm proud of delivering a full-stack web application that looks clean, works fast, and feels premium, from dynamic QR generation to live analytics and secure URL validation. It’s all custom-built, privacy-conscious, and production-ready.

What we learned

I deepened my experience with Supabase RLS, edge functions, and real-time subscriptions. I learned how to balance UX polish with robust security and performance at scale. Using Bolt.new helped me prototype layouts and components faster. Letting me focus more on backend complexity and data security.

What's next for QR Nexus

Next, I'll add advanced analytics exports and deeper scan insights. I'm also exploring AI-driven design suggestions and expanding the template system.
