slicer

A modern Java reverse engineering tool for the web.

Features

• disassembly and decompilation of Java class files
  • CFR, JASM, Vineflower, Procyon, ...
• bytecode control flow visualization via a CFG
• low-level tabular view of a class file
• heap dump reading and summarization
• simple hexadecimal viewer for binary files
• a simple JS scripting API for doing various things
• shadcn/ui design and theming support

Installation

slicer and all decompilers/disassemblers run in the browser, no download necessary, just go to https://slicer.run!

If you want a desktop app (-ish) experience, you can also install slicer as a PWA.

Motivation

All of this has stemmed from an experiment of running the CFR Java decompiler in a browser using TeaVM, which ended up working pretty well, so I made this thing around it.

slicer's being built for the sake of having fun building it, so don't expect any crazy features - if you want to do serious reverse engineering, use Recaf; if you want to quickly look at a class file, and you don't want to set anything up locally, stay here.

This is what happens when you let a backend developer do frontend, so enjoy the programmer art design.
