Code Rule and Code Query
Hundreds of default code rules to check against best practices. Support for Code Query over C# LINQ (CQLinq) to easily customize rules and query code.
Easily Manage Large Projects
Most companies have large systems that work together, often in mysterious ways. NDepend's in-depth reporting and toolset can help your company enforce its own coding standards and maintain complex projects.
Powerful Dependency Graph and Matrix
Explore how the code is actually structured and shed light on architectural flaws thanks to the most powerful code dependency graph and dependency matrix available in the tool industry.
Smart Technical Debt Estimation
For each issue, the cost to fix and the severity are estimated through smart and customizable C# formulas. Thus estimations proposed are realistic.
Continuous Code Quality
A unique approach to continuously keep the technical debt under control and reimburse it with time.
Quality Gates
Quality Gates are C# LINQ (CQLinq) queries that implement PASS/FAIL criteria to code quality.
In-Depth Issues Management
Explore the issues-set in a few clicks and focus your effort on what is urgent and important.
Harness Test Coverage Data
Import test coverage data, and make the most of it in the NDepend feature-rich context.
Monitor the Health of Your Application
NDepend allows your team to accurately gauge the overall health of your application, no matter how complex it is.
Trend Monitoring
Get Trend Charts about pretty much any code metrics to master the evolution of your application.
Code Diff since Baseline
Compare two versions of a code base and its issues set, and browse diff and changes in any way you can think of.
Warnings on Build Process Health
Be warned of potential build process problems before they end up causing friction and pain.
Reduce Friction Between Your Developer Teams
NDepend's reporting and analysis helps architects and developers to communicate and reduce confusion.
Continuous Integration Reporting
Integrate NDepend analysis into your build process and get highly customized and detailed reports to see progression and prevent code quality degradation.
Complexity and Diagrams
Spot too complex code at a glance thanks to unique diagramming capabilities.
Code Quality and Code Metrics
Lines of Code, Cyclomatic Complexity, Coupling, Nesting Depth, Rank, NDepend supports them all (and much more).
Working with Legacy Code is Now Easier
By mapping out the structure of the project, it is much easier to see how components and dependencies are connected.
Detect Dependency Cycles
Get rid of dependency cycles between components to achieve higher code maintainability.
Enforce Immutability and Purity
NDepend helps maintaining clean side-effects free code to write highly maintainable products.
Real-World Proof
Full Visual Studio and Azure DevOps integration, super fast and lightweight analysis, integration within all CI/DevOps systems, NDepend is conceived for real-world programmers.
NDepend.API and Power Tools
Write your own static analyzer based on NDepend.API, or tweak existing open-sources Power Tools.
Code Quality and Code Metrics
There are many ways to measure a code base. The most common way is to count the number of lines of code. This metric gives a rough estimation of the effort that had been put in to develop the code base. It also allows you to obtain a quality level agreement by pinpointing fat methods and classes.
NDepend counts the number of lines of code. It also comes with 82 other code metrics. Some of them are related to your code organization (the number of classes or namespaces, the number of methods declared in a class...), some of them are related to code quality (complexity, percentage of comments, number of parameters, cohesion of classes, stability of assemblies...), some of them are related to the structure of code (which types are the most used, depth of inheritance...) and some of them are related to code coverage (%coverage, number of lines of code covered, branch coverage...).

NDepend also provides some facilities that will help you to detect metric anomalies and to fix your own thresholds.
The NDepend UI displays an interactive view of code metrics of your .NET applications. Such a view can be tuned according to numerous software metrics and can be saved in a PNG file in order to let you print posters.
For example see below a screenshot below of the metric view on the NDepend code base:
- Rectangle are methods of the code base.
- Each rectangle area is proportional to the #lines of code of the method.
- and the rectangle color is defined by the percentage coverage by tests of the method.
