## What it is
A web service (like Compiler Explorer in reverse) that lets users upload small binaries and compare the decompiled C-like output from many decompilers such as Ghidra, Binary Ninja, Hex-Rays, angr, and RetDec side by side. It is open source and can be self-hosted via Docker, though public instances may not include commercial decompilers due to licensing.

## Use cases
- compare decompiler output for a binary across multiple tools
- decompile an executable back to C-like pseudocode online
- evaluate which decompiler works best on my binary
- analyze a CTF challenge binary in the browser
- reverse engineer a small binary without installing tools
- self-host a decompiler comparison service

## When to choose
- you want to compare outputs of many decompilers on small binaries quickly
- you want a browser-based reverse engineering workflow with no local setup
- you want to self-host a decompiler playground with open-source decompilers

## When to avoid
- you need to decompile large binaries over 2MB
- you need a full interactive reverse engineering IDE with debugging
- you want to run a public instance including commercial decompilers like Hex-Rays or Binary Ninja (license restrictions)
- you need offline analysis of sensitive binaries you cannot upload
