NDepend

NDepend is a static code analysis tool for .NET codebases that provides code quality and security insights through an interactive web report, dependency graphs, quality gates, and customizable C# LINQ-based rules. It runs on-premises and integrates with Visual Studio, Azure DevOps, GitHub Actions, and other CI/CD platforms.

Its main features include a dependency graph and matrix, code metrics such as lines of code, cyclomatic complexity, coupling, and nesting depth, trend charts, test coverage data import, code diff since baseline, and technical debt estimation. Quality gates are customizable PASS/WARN/FAIL criteria written in C# LINQ queries. NDepend imports issues from Roslyn Analyzers and ReSharper Code Inspections, and its MCP Server allows AI coding assistants to detect and fix issues. It runs on Windows, macOS, and Linux, and supports .NET versions from .NET Framework 4.x through .NET 10, including ASP.NET Core, Blazor, Xamarin, Unity, and UWP.

NDepend is packaged in Developer and Build-Machine editions, with a 14-day free trial available. It integrates with Visual Studio, Azure DevOps, GitHub Actions, and other CI/CD pipelines, and can also be used alongside Visual Studio Code and Rider through a standalone application.
