ndepend : The .NET Code Quality and Security Tool

Ready for AI-Assisted Coding


  • 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.
  • Privacy: analysis runs on your premises, your code never leaves your infrastructure.
  • Unlike slow, complex, and costly cloud 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
  • With the growing amount of code generated by AI tools, maintaining consistent quality and architecture standards becomes more challenging.
  • NDepend automatically review AI-generated code with the same rigor as human-written code.
  • Instantly detect quality issues, architectural drift, and technical debt introduced by GenAI.
  • Gain confidence in AI-generated code by ensuring it meets your quality standards and long-term maintainability requirements.
  • Code maintainability improves, directly boosting team productivity.
  • Issues in AI-generated code are automatically detected and fixed, giving teams confidence that even AI-assisted changes maintain high quality standards.
  • 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.
  • With the NDepend MCP Server issues can be browsed and automatically fixed, helping you maintain code quality effortlessly. This works with all AI code assistants such as VS2026, VSCode GitHub Copilot, and JetBrains Juny.
  • All the guidance provided for human developers directly helps the AI assistant understand and fix issues properly.
  • In addition to issues found by the NDepend Rules, Roslyn Analyzers and Resharper Code Inspections issues can be imported into NDepend. The tool detects which issue is new, unresolved or fixed against a baseline.

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."
