ndepend : The .NET Code Quality and Security Tool

Analyze all .NET versions ; Works with all .NET IDEs and CI/CD technologies ; Run on Windows, MacOS and Linux

  • Integrate with NEW Visual Studio 2026, 2022, 2019, 2017, 2015, 2013, 2012 and 2010, with Azure DevOps / TFS, with GitHub Action and all other DevOps platforms
  • All features available side-by-side with Visual Studio Code and Rider thanks to the standalone app VisualNDepend.exe
  • Analyze NEW .NET 10.0, .NET 9.0, .NET 8.0,  .NET Core,  .NET Fx 4.x,  ASP.NET Core,  Blazor,  Xamarin,  Unity  and  UWP  application
  • Runs on WindowsmacOS and Linux    NDepend runs on Windows, macOS and Linux

  • NDepend delivers deep .NET code quality and security insights through an interactive web report.
  • See sample reports from popular .NET OSS projects.
  • Reports are generated in seconds via a DevOps task — compatible with all CI/CD tools and OS.
  • Your code stays 100% private: analysis runs entirely on your premises, and we never access your code.
  • Unlike slow, complex, and costly cloud or server-based solutions, NDepend is fast, simple, and secure.
  • As a static analyzer, NDepend is likely to identify numerous issues that impact your codebase. Halting work to address all these issues for weeks would be highly unproductive.
  • This is precisely why NDepend suggests to focus on progress since a baseline snapshot of your code base. The tool estimates the technical debt delta since the baseline.
  • The tool highlights recent code smells, vulnerabilities, and regressions that should be fixed before committing to source control—this is even more critical when working with GenAI code.
  • As a result, the Code Quality remains under control with no substantial upfront investment.

  • A Quality Gate is a code quality criterion that must be enforced before releasing and eventually, before committing to source control.
  • A dozen of default Quality Gates are continuously checking measures such as overall Code Coverage by tests or Technical Debt added since baseline.
  • With NDepend, a Quality Gate is a C# LINQ query easy to customize and create. This unique approach offers the required level of flexibility to enforce what really matters for your organization.

Because a picture is worth a thousand words, NDepend — the industry leader solution for code visualization and navigation — offers several unique ways to explore and understand your code:

     NDepend Dependency Graph
  • Developer time is priceless—and NDepend is lightning fast. Web reports are generated in seconds, while other tools can take minutes or even hours.
  • With every compilation, your overall technical debt is instantly updated in the IDE or in a side-by-side app—no slowdowns, no waiting.
  • New issues and regressions are flagged immediately, so developers can tackle them while the context is fresh and work stays smooth.
  • Code maintainability improves, directly boosting team productivity. Over time, developers internalize best practices, sharpen their skills, and write better code naturally.
  • Architects gain foresight into the impact of code changes, enabling the right decisions early.
  • With 360° code insights—powered by NDepend rules, Roslyn Analyzer and R# Code Inspection, teams continuously deliver higher-quality secure code, both in the IDE and across DevOps pipelines.
  • This clarity also empowers executives to manage costs and risks effectively, providing actionable insights into the development trends and metrics that matter most.
  • Issues generated by any Roslyn Analyzer or Resharper Code Inspection can be imported in the NDepend model.
  • This means that all aspects of .NET Code Quality and Security can be monitored through NDepend.
  • When comparing against a baseline, NDepend detects which Roslyn Analyzer or Code Inspection issue is new, unresolved or fixed since the baseline.
  • Use the NDepend Quality Gates feature to stop the build if some Roslyn Analyzers failure conditions are met. See an NDepend report importing Roslyn Analyzer here.

Daily Life Saver

"As someone who gets to work with other people code daily I found NDepend to be a real life saver in such cases."
Dror Helper, Freelance Consultant & Software Architect
David Shifflet

Architecture

"The issues NDepend raised for me seemed to be more related to architecture issues versus the other tools. It definitely gave me insight into what to refactor and how to reduce technical debt."
David Shifflet Senior Software Developer

Recent Reviews from around the web

"Tools like NDepend are required for teams dealing with proper code reviews, examining code when code is idle (like on weekends), or when you have a possible circular reference in play.

NDepend not only has a great static code analysis tool, but also provides a way for veteran developers and aspiring architects alike to adhere to coding standards along with a way to integrate a company's coding standards into the tool using CQLINQ.This is definitely a tool for advanced developers and one that I definitely recommend to anyone looking to analyze a code base."

"NDepend found enough problems in my code. Some of them are really helpful. I like that NDepend found 10 classes which can be changed to structures. Structures are extremely effective from the memory pressure perspectives. This is especially important when we’re talking about mobile applications."
