monsoon

A fast HTTP enumerator that allows you to execute a large number of HTTP requests, filter the responses and display them in real-time.

Example

Run an HTTP GET request for each entry in filenames.txt, hide all responses with the status code 403 or 404:

basic demo

Common usage of monsoon is also covered in our blog article "Introducing monsoon - a lean and versatile HTTP enumerator".

Installation

Building from source

These instructions will get you a compiled version of the code in the master branch.

You'll need a recent version of the Go compiler, at least version 1.14. For Debian, install the package golang-go.

Clone the repository, then from within the checkout run the following command:

$ go build

Afterwards you'll find a monsoon binary in the current directory. It can be for other operating systems as follows:

$ GOOS=windows GOARCH=amd64 go build -o monsoon.exe

Unofficial Packages

For Arch Linux based distributions monsoon is available as an unofficial package on the AUR. Using your AUR helper of choice such as yay:

yay -S monsoon
