ILSpy vs rev.ng

ILSpy is free, open-source software for browsing and decompiling .NET assemblies on Windows, Linux, and macOS. Its Avalonia desktop interface converts assemblies to C#, including whole-project decompilation. Assemblies can come from disk, NuGet, running processes, or the Global Assembly Cache, although GAC support is limited to Windows. Search covers types, methods, and properties, with hyperlinks, bookmarks, base and derived type navigation, and an assembly metadata explorer. The application also includes BAML-to-XAML decompilation and support for ReadyToRun binaries for .NET Core. Related tooling includes Visual Studio 2022/2026 support, Visual Studio Code extensions, the ilspycmd dotnet tool, PowerShell cmdlets, and NuGet packages. Desktop plugins and a scripting API extend its use. ILSpy supports bytecode decompilation but not native-code decompilation. The project says it does not collect personally identifiable information, send user files to third-party services, or use application performance monitoring for telemetry. Release 11.1 is listed as the latest version, under the MIT License.

rev.ng is a decompiler for reverse engineering that turns supported binaries into syntactically valid, standard-compliant C. Its data-structure recovery uses information across functions to identify linked lists, structs, arrays, and arrays of structs. The listed default architectures are x86, x86-64, ARM, AArch64, MIPS, and S390X; supported imports include ELF, PE/COFF, Mach-O, DWARF, PDB, and IDB. Users can define functions, edit prototypes, and rename items in YAML files, or interact through an HTTP API. The interface is described as available in a browser or standalone app, with cloud and standalone use offering the same experience. Collaborators can share a project URL; public projects include two collaborators. The rev.ng decompilation pipeline is Free Software, while the UI is intended for commercial cloud and standalone versions. The service is free and lists API, Linux, macOS, web, and Windows platforms. The site invites users to join a closed beta for the UI.
