Desktopfreeglobal

JD-GUI Duo is a free, open-source, multi-decompiler desktop GUI for Java and Android bytecode, bundling six decompilers (JD-Core, CFR, Procyon, Fernflower, Vineflower, Jadx) in one tool. It's for developers and security researchers who reverse-engineer .class, .jar, .dex, or .apk files and want to cross-check decompiler output without switching tools.
