Building a Fast, Free Online QR Scanner and Generator (Open Source)

Hi Dev Community! 👋

I wanted to share a project I recently launched: QRScanner.

Most online QR code tools out there are either hidden behind a paywall, filled with annoying pop-up ads, or force you to download an app. I wanted a clean, fast, and privacy-focused alternative, so I decided to build one myself!

it's fully hosted on Netlify and open-source.

🚀 Live Demo & Repository

• Live Tool: [https://qrscaner.netlify.app/](https://qrscaner.netlify.app/)
• Features: Scan via Camera, Upload Images, and Generate custom QRs (WiFi, WhatsApp, Text, URLs).

🛠️ Tech Stack & Features

I kept the architecture lightweight and straightforward to ensure maximum speed directly in the browser:

• HTML5 / CSS3: Custom UI with a clean dark/light theme experience.
• Vanilla JavaScript: Fast decoding logic without heavy framework overhead.
• Privacy First: No data is sent to any server; everything happens locally on your device.

💡 What I Learned

Building this project helped me understand browser-based camera permissions better and how to optimize image scanning directly from the device gallery efficiently.

I would love to get your feedback on the UI, performance, or any features you think I should add next. If you find it useful, feel free to bookmark it or star the repo!
