dnSpyEx vs JEB

dnSpyEx is an unofficial continuation of dnSpy, a debugger and .NET assembly editor for working with assemblies without source code. It can debug .NET Framework, .NET, and Unity game assemblies, with breakpoints, tracepoints, conditional breakpoints, exception breakpoints, and multiple-process debugging. Editing covers metadata and methods or classes in C# and Visual Basic, plus low-level IL method bodies. The project lists C# and Visual Basic decompilers using the ILSpy engine, along with a BAML decompiler and disassembler. Assembly search, class and method usage analysis, caller finding, bookmarks, and project export are also included. A public API supports extensions, and the C# Interactive window can control or script dnSpyEx. The latest stable release listed is v6.6.0, which adds a .NET 10 distribution. It is free under GPLv3. Release notes describe Wine compatibility adjustments for Linux, not native Linux support. Dynamic methods cannot be debugged because of CLR limitations.

JEB is a reverse-engineering platform for disassembly, decompilation, debugging, and analysis of code and document files. Its Android tools support static and dynamic app analysis, including multi-dex decompilation, resource reconstruction, and debugging of Dalvik and native code. Other modules address Intel x86 and x86-64, ARM, MIPS, RISC-V, WebAssembly, Ethereum contracts, Siemens S7 PLC programs, and PDF documents. Python or Java scripts and plugins can automate analysis, including through headless front ends. The GUI runs on Windows, Linux, and macOS for x64 and arm64 systems and requires JDK 21 or above. JEB Community Edition is free and described as suitable for researchers, students, hobbyists, and nonprofit reverse engineers; its listed plan covers x86 and x86-64 decompilation. The separate demo restricts decompilation, disables project saving and loading and clipboard use, limits session time, and requires an internet connection. Paid plans include Android modules from $140 per user per month and JEB Pro from $2,000 per user per year. PNF Software was founded in 2013 and is based in Silicon Valley, California.
