BruteXSS is a tool written in python simply to find XSS vulnerabilities in web application. This tool was originally developed by Shawar Khan in CLI. I just redesigned it and made it GUI for more convienience.
This tool is developed in Python, so obviously cross platform, you just need Python installed in your machine.
Just download your tool & run brutexss.py (Everything this tool needed is provided to it)
