Professional Code Analysis Tool

The Static Code Checker is a comprehensive tool designed to help developers identify and fix issues in their code before deployment. Whether you're a beginner learning to code or an experienced developer working on complex projects, this tool provides valuable insights to improve code quality, security, and maintainability.

What Our Code Checker Analyzes

Syntax Errors

Detect missing semicolons, unmatched brackets, undefined variables, and other syntax issues that prevent code from running properly.

Best Practices

Identify code style violations, unused variables, inefficient patterns, and suggestions for better coding practices.

Security Warnings

Flag potential security vulnerabilities like use of eval(), SQL injection risks, and unsafe practices that could compromise your application.

Code Smells

Detect complex functions, deeply nested loops, code duplication, and other indicators of poor code structure that may need refactoring.

Supported Languages

Our Static Code Checker supports multiple programming languages, each with its own set of rules and best practices:

  • JavaScript/TypeScript: ES6+ features, async/await patterns, module imports, and modern JavaScript best practices
  • Python: PEP 8 style guidelines, type hints, list comprehensions, and Pythonic patterns
  • Java: Object-oriented principles, exception handling, and Java coding conventions
  • C++: Memory management, STL usage, and modern C++ features
  • PHP: PSR standards, security practices, and modern PHP patterns
