Documentation

Welcome to the RECQR documentation. Learn how to instantly scan, decode, and generate QR codes at the edge using our platform and APIs.

Experience the blazing fast client-side decoding immediately.

Generate beautiful SVG/PNG codes with our easy-to-use tool.

Why RECQR?

Most QR code platforms are slow, littered with ads, and require a backend server just to decode an image. RECQR flips this paradigm.

100% Client-Side Scanning: We use WASM and modern browser APIs to decode QR codes directly on your device. Your camera feed never touches our servers.
Rich Payloads: Automatically identifies WiFi, vCards, Calendar Events, Geo-locations, and Maps them to beautiful, actionable UI cards.
Edge API: Our generator API is hosted on Cloudflare Workers, meaning the generation happens on an edge node just milliseconds away from your users.

Want to host RECQR yourself? It's a statically exported Next.js 14 application that can be deployed to GitHub Pages, Vercel, or Netlify instantly.

Terminal
