introduce the best free auto coding sites.

There are several websites available that offer free automatic programming or code generation services. Some of them include:

1. Codex - A platform that provides code generators for popular languages such as Python, JavaScript, Java, C++, etc.

 Users can create custom templates and share them with others. They also have a marketplace where you can buy and sell 

templates.

2. Jexia - Another platform that offers code generators for various use cases like CRUD operations, REST API, 

mock servers, database migration scripts, etc. It supports multiple languages including Python, JavaScript, SQL, 

Ruby, and more.

3. Flatline - An open source project by Google that allows developers to generate boilerplate code quickly from a set of 

annotated examples. Currently supported only for Dart and Go language but might extend support for other languages in future.

4. Autopep8 - A command line tool that automatically formats and reformats your Python code according to PEP 8 style guide.

 This helps maintain consistent indentation levels and makes it easier to read and understand the code.

5. Sphinxautogen - A Python script that generates configuration files for documentation projects using the Sphinx framework.

 It parses your existing documentation and creates configurations for different output formats like HTML, LaTeX, and PDF.

These tools can help speed up development time by automating repetitive tasks and ensuring consistency across your codebase.

 However, keep in mind that they should be used judiciously and not become a crutch for learning fundamentals

 or writing quality code.
