Bytecode Viewer

Targeted at developers, Bytecode Viewer is an effective application that bridges the gap between compiled Java bytecode and readable source code. It integrates multiple robust decompilers—such as CFR, FernFlower, and Procyon—into one interface, letting you switch between them to get the clearest possible reconstruction. You can analyze method instructions, constant pools, and control flow directly. This tool is perfect for debugging tricky runtime issues, studying compiler output, verifying optimizations, or conducting security assessments on third-party libraries without needing the original source.
