Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited performance for generating large volumes of QR codes

   Pure Python implementation can be slower compared to native or compiled libraries, especially when generating a high volume of QR codes.

2. 02

   Lack of advanced customization options beyond basic appearance settings

   The library focuses on core functionality and does not support more complex customizations such as embedding logos or advanced styling features found in other libraries.

3. 03

   No built-in support for reading QR codes

   The tool is exclusively designed for generating QR codes, and developers must rely on separate tools or libraries to read the generated QR codes, which can complicate integration efforts.

4. 04

   Documentation lacks comprehensive examples and use cases

   While basic usage is covered, detailed documentation for advanced features and edge cases is sparse, making it harder for developers to fully leverage the library's capabilities.

What it does well

• Pure Python implementation, no external dependencies required.

• Supports various QR Code versions and error correction levels.

• Flexible customization options for QR code appearance.
