Why I built a lightweight, ad-free QR Scanner using Web Technologies

说明与用途

Fast QR Scanner 是一个轻量级、无广告的基于浏览器的二维码扫描器，所有处理在客户端完成，保证隐私和性能，且不依赖重库。

问题

Existing QR scanner apps are bloated, require many permissions, and contain intrusive ads.

结果

Fast QR Scanner provides a fast, privacy‑preserving QR scanning experience without ads or heavy dependencies.

工作流

• 1. Capture camera stream via getUserMedia
• 2. Decode QR code in the browser using lightweight algorithm
• 3. Display decoded data to the user

证据

Most of the QR scanner apps available today are bloated. They take too much space, require unnecessary permissions, and are often riddled with intrusive ads.

来源

All the decoding happens right in the browser. No images are uploaded to a server, ensuring 100% privacy.

Zero Dependencies: I wanted the tool to be lightning-fast, so I avoided heavy libraries.
