dnSpy vs ILSpy
GitHub Stats
About dnSpy
dnSpy is a debugger and .NET assembly editor that allows you to decompile, modify, and debug .NET assemblies even without source code. It includes a full-featured debugger that can debug .NET Framework, .NET Core, and Unity game assemblies, with support for breakpoints, stepping, locals, watch windows, and the immediate window. The decompiler produces readable C# or Visual Basic code from compiled assemblies, and the built-in editor allows direct modification of IL code, metadata, and resources. dnSpy is an essential tool for malware analysts examining .NET malware, reverse engineers working with Unity games, and security researchers analyzing compiled .NET applications. While the original repository is archived, several actively maintained forks continue development.
About ILSpy
ILSpy is the open-source .NET assembly browser and decompiler. It supports decompilation of .NET assemblies to C# with high-quality output, including support for modern C# features like async/await, LINQ, and pattern matching. ILSpy can decompile entire assemblies or individual types and members, with the ability to search across loaded assemblies and navigate type hierarchies. It supports .NET Framework, .NET Core, .NET 5+, and Mono assemblies. Unlike dnSpy, ILSpy focuses purely on decompilation and browsing rather than debugging and editing, making it lighter and more focused. It's available as a standalone Windows application, a VS Code extension, and a command-line tool (ilspycmd) for cross-platform use. ILSpy is actively maintained and is the most widely used open-source .NET decompiler.
