About Free Online Codebase Dependency Visualizer

The Free Online Codebase Dependency Visualizer is an advanced interactive tool designed for developers, software architects, and code reviewers who need to quickly comprehend a new codebase. When joining a new project, reading thousands of lines of code to understand how files and functions correlate is incredibly time-consuming.

Our tool scans multiple code files simultaneously, parsing imports, exports, class definitions, function structures, and function calls. It builds an interactive, zoomable codebase map showing file-to-file imports and detailed function-to-function call correlations.

Built entirely for local execution, your source code never leaves your device. No files are uploaded to our servers, keeping proprietary code bases and logic fully secure and private.
