Binary Ninja vs ILSpy

Binary Ninja is a binary analysis platform that combines an interactive decompiler, disassembler, and debugger. Its decompiler can produce C or BNIL for supported architectures, and users can switch between those outputs. The API provides C++, Python, and Rust bindings for automating workflows inside or outside the interface. A native debugger supports local and remote sessions on Windows, macOS, and Linux. Paid editions support plugins managed through an in-client Plugin Manager; plugins are not available in the Free edition. The browser-based Cloud version supports all architectures but requires submitted binaries and has performance limits, with no API or plugins. The free desktop edition is for evaluation or non-commercial use and lacks API access; the Free plan lists five decompilation architectures, while desktop details state four. Paid perpetual client licenses start at $199, paid once for Personal, with one year of updates and non-commercial use. Higher tiers add commercial use, more architectures, or remote project features. Binary Ninja is made by Vector 35.

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.
