JavaScript HTML Binary Exploitation ROP

Parses standard rp++ text output (address: instructions) for immediate analysis
Supports common architectures and workflows used in Windows/Linux ROP development
Interactive filtering, full-text search and downloadable analysis summaries

What is it?

A browser-only ROP (Return-Oriented Programming) gadget analysis tool. Load a raw helper output file from rp++ (a popular ROP gadget finder) and the tool immediately categorises, filters, and summarises every gadget — with zero server involvement and zero install required.

ROP chains are a technique for bypassing non-executable memory protections (NX/DEP) in binary exploitation. Building them from thousands of gadgets in a large .txt file is tedious — this tool tames that.

Who is it for?

Security researchers and CTF players building ROP chains for Windows or Linux exploitation. Useful anywhere you have a large rp++ output and need to quickly find the right gadget class without grepping manually.
