Why?

Static code analysis is a game-changer for improving code quality. It helps you catch potential issues early, enforce coding standards, and gain deeper insights into your codebase.

With AST Metrics, you can:

• Get a bird's-eye view of your project: Quickly identify overly complex code or tightly coupled classes that could slow down your development or introduce bugs.
• Enforce architectural coherence: Ensure your code structure aligns with best practices—for instance, making sure your service layer doesn’t depend on your data access layer.

Whether you're maintaining an existing codebase or building a new one, AST Metrics empowers you to write better, more maintainable code.

Features
