Understand is a comprehensive static-analysis and code-comprehension platform that helps software engineers “see” and understand large, complex code bases, whether legacy, safety-critical, or modern multi-language projects. It parses your source code and builds a complete “code dictionary” of every entity (files, classes, functions, variables), populating cross-references, call trees, dependency graphs, control-flow diagrams, and more. Through interactive, customizable graphs and visualizations, call graphs, control flow graphs, dependency trees, and UML-style class diagrams, you can explore exactly how parts of the code connect, which modules depend on which, and where changes may ripple across the project. Understand also computes detailed metrics at various levels (file, class, function) such as cyclomatic complexity, lines of code, comment-to-code ratio, coupling/cohesion, and other maintainability indicators; these metrics can be viewed in treemaps, exported to HTML or CSV.
