LEGACY CODE

Understand your Code

Have you recently inherited confusing legacy code? Understand is here to help.

Analyze Dependencies

Blindly changing legacy code can lead to disaster. Know what your changes will affect before you even start writing.

Navigate Cross-References

Navigating legacy code doesn't need to feel like an endless maze. Quickly navigate references to create a mental map of the code base.

View Call-Trees

Expand a function's call tree to see what any changes might affect. You can also view Butterfly, Control Flow, and many other useful graphs.

Static code Analysis

Verify your Code

Does your project require strict coding standards? Understand has the capability to check your code against industry, common, or custom standards.

Introducing CodeCheck, our code compliance solution

CodeCheck can be integrated into your CI/CD pipeline to run with every code check-in and notify team members when a compliance check has failed.

Checks against industry standards like Autosar and MISRA C/C++
Our recommended checks come standard, employing many coding best practices
Let our trained software engineers write your custom standards for you! Learn How

GRAPHS

Visualize your Code

Quickly see how your source code is structured, organized, and related. See Control Flow, Call Trees, Dependency, Butterfly, UML Class, and many other graph types. All our graphs are interactive and customizable, expand or contract your graph to see exactly what you need.

METRICS

Quantify your Code

Do you need help locating the "problem" areas in your code? Understand comes bundled with dozens of metrics that help with exactly this scenario.

Measure Twice, Code Once

Understand your code's cyclomatic complexity by using various browser and display options
Receive detailed metrics about your code at the file, class, and entity levels
Export a full list of your metrics to an HTML or CSV file
CUSTOM SCRIPTING

Automate your Code

Do you prefer complete control over your coding environment? Understand comes bundled with a robust API to unlock your project's full potential.

An API for Toolsmiths

Our API allows the creation of custom graphs, metrics, and lexical analysis. Integrating with your current tools is now easier than ever! Learn More

Continuous Integration

Verify code compliance, ensure code complexity stays below a specified threshold, or email the team a code comparison graph all from your existing pipeline. Learn More

Custom Scripting

Create and enforce any custom coding standard. We can teach you how to write a standard or simply hire us to handle the entire process for you! Learn More

Hyper-Xref

Explore your Code

Navigating complex code relationships has never been easier. Hyper-Xref technology and the tools in Understand make you a safer, smarter engineer less likely to add bugs as you change code.

Code comparison

Compare your Code

Quickly see the difference between two project states. View changes by files, folders, entities or architectures. View your changes as a text comparison or in a tree map. Just specify the git revision you would like to compare against or compare two databases.
