Five Reverse Engineering Tools, From Screenshot to Machine Code

Any developer can now peel open software at five distinct levels, from a rendered page to raw machine code, using the same open-source stack that security researchers rely on, without costly licenses or specialized training. The progression also shows how reverse engineering is broadening beyond binary analysis to include AI-assisted code generation from visual input.

A new roundup of reverse engineering tools lines up five well-maintained open-source projects in order of increasing depth. screenshot-to-code starts by converting screenshots, design files, or even screen recordings into runnable front-end code, a first step that re-implements a visible interface. mitmproxy intercepts network traffic, including TLS-encrypted HTTPS, by installing a local CA certificate and proxying requests through port 8080. Apktool unpacks Android APKs into human-readable resources and smali bytecode, allowing modifications and re-packing. jadx goes further by decompiling dex files back into Java source with partial de-obfuscation and debugging support. At the deepest level, Ghidra, the NSA's open-sourced framework, disassembles and decompiles raw binaries into assembly and pseudo-C, supporting a wide range of processors and executable formats.

Each tool carries its own installation path and typical use cases. screenshot-to-code runs via Docker and supports six output stacks including React, Vue, and Tailwind, with the ability to compare multiple AI models in one generation. mitmproxy offers three interfaces: an interactive terminal, a command-line dump tool, and a web-based UI, with addons for scripting. Apktool and jadx are often paired for Android work, one for resource editing and re-packing, the other for reading Java code. Ghidra requires a 64-bit JDK 25 and is the go-to for malware analysis and CTF challenges. The article also notes legal boundaries, emphasizing that these tools shouldn't be used for piracy or unauthorized cracking.
