Our verdict on Understand
Understand is a desktop static-analysis and code-comprehension tool for developers working with large, legacy, mixed-language, or safety-critical codebases. It creates cross-references for functions, classes, variables, files, and relationships, then presents dependencies, call trees, control flow, butterfly diagrams, and UML graphs. The product also covers code metrics, standards compliance, defect checks, code comparison, and scripting through APIs and command-line workflows. Its language coverage spans Ada, Assembly, C, C++, Objective-C, CUDA, C#, Fortran, Java, JOVIAL, Pascal/Delphi, Python, Rust, VHDL, Visual Basic/VB.NET, HTML, CSS, JavaScript, TypeScript, PHP, and XML.
Pricing divides into a Developer license and an Open Source plan. The Developer license is listed at $100 per user per month with annual billing and provides desktop code-comprehension and static-analysis features. The Open Source plan is free for qualifying projects in public Git repositories and provides full functionality when eligibility requirements are met. This makes the product more accessible for eligible public projects, while commercial teams should budget for the annual subscription and its 12-month minimum. Exact commercial cost can vary by geography and license count.
Understand fits teams that need more than isolated linting: its CodeCheck capability supports standards such as MISRA and AUTOSAR, while Bug Hunter checks for memory leaks, dangling pointers, and null dereferences. Custom coding standards, rules, graphs, metrics, and plugins extend its analysis model. It supports Windows, macOS, Linux, API workflows, CI/CD, self-hosted deployment, Visual Studio Code, SlickEdit, Emacs, and Vi. Choose it when broad program comprehension and configurable analysis matter; choose a narrower tool when a simpler workflow is the priority.
