What it is: - A fast CLI tool and library for generating QR codes - Written in C++ with bindings for Ruby, PHP, and Node.js - Full UTF-8 support (works great with Vietnamese, Japanese, and other languages) - Supports custom colors, logo embedding, and precise size control - Pre-built binaries included – no need to install dependencies separately
Why I built this: - I needed a QR code generator that was fast, supported UTF-8 properly (especially for Vietnamese text), and could be easily integrated into different languages. Most existing solutions were either slow or had poor Unicode support.
Performance: - Generating 1000 QR codes (500x500px): ~0.37 seconds
Tech stack: - C++ core using libqrencode and libpng - Language bindings for Ruby, PHP, and Node.js - Precompiled binaries for easy installation
This is my very first open-source project, so I'm sure there are things that could be improved or bugs I haven't caught yet. I'd really appreciate it if you could try it out and share your feedback. If you find any issues or have suggestions, please open an issue on GitHub – I'll do my best to fix them quickly.
Any feedback, criticism, or suggestions would be greatly appreciated. Thanks for taking the time to check it out!
