Does your project require strict coding standards? Check your code against common, standards.
Code Comparisons
Quickly see the difference between two project states. View changes by files, folders, entities or architectures.
Graphs
VIsualize your code with Control Flow, Call Trees, Dependency, Butterfly, UML Class, and more.
Metrics
Receive detailed metrics about your code at the file, class, and entity levels.
Custom Scripting
Our API allows the creation of custom graphs, metrics, and lexical analysis. Integrating with your current tools is easy!
Code Exploration
Cross reference technology makes you a safer, smarter engineer less likely to add bugs as you change code.
Onboarding
New members to your team can hit the ground running faster than ever with our code comprehension tools.
Legacy Code
Understand confusing legacy code easily with our dependency analysis, cross references, and call trees.
Praise From The U.S. Navy
Understand has been Spotlighted by the U.S. Navy's SBIR Transition Program
Understand helps hundreds of companies and government organizations, including the U.S. Navy, stay code compliant with our CodeCheck tool.
"NSWCDD needed a tool to ensure that their projects worked correctly and to ensure that the coding complied with the Navy Strategic Systems Program (SSP) coding standard. As an established tool that was reliable but also dynamic, flexible, and customizable, Understand piqued their interest."

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.
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.
Customizable Rules
All rules come standard with every installation of Understand.
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.
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.
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
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

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.
Understand contains a built in IDE that facilitates code browsing. Click on any entity (function, class, variable, etc) to see detailed information and double click to be taken directly to where the entity is defined. Every named part of your code is referenced and can be bi-directionaly navigated.
Keep the Information Browser pinned while you work to quickly see everything Understand knows about a selected entity. The Information Browser updates depending on what you have selected.
For functions, see the return type, paramters, and a list of references that take you to that instance immediately when clicked.
For files, see the member variables and functions, a list of includes, and relevant metrics.
Graphs can also be accessed from the Information Browser or by right clicking any named entity in your code. Quickly see everything that calls or is called by a specific funtion with a Butterfly Graph.
Explain your Code
Give your new engineers the tools they need to succeed. Understand helps onboard new engineers rapidly and safely.
- Coding standard enforcement
- Quick understanding of new code bases
- Annotations shared between engineers
- Graphs of your code worth 1000 words of explanation
- High level architectural views of code putting everything in context
