code2flow
Generates call graphs for Python, JavaScript, Ruby, and PHP to visualize code structure and dependencies.
What is code2flow?
Code2flow is a static analysis tool that generates call graphs for dynamic programming languages like Python, JavaScript, Ruby, and PHP. It helps developers visualize the flow of function calls in their codebase to understand dependencies, untangle complex logic, and identify unused functions. The tool uses AST parsing and heuristics to approximate call relationships where exact determination is impossible due to dynamic language features.
Developers working with dynamic language codebases who need to understand, refactor, or document complex projects, especially those dealing with legacy or spaghetti code. It's also useful for technical leads onboarding new team members.
Code2flow offers a practical, multi-language solution for call graph generation where perfect accuracy is unattainable. Its straightforward CLI and library interface, combined with the ability to filter subgraphs, make it a lightweight yet powerful tool for code exploration without heavy IDE dependencies.
