Just, XSS Scanning and Parameter Analysis tool. I previously developed XSpear, a ruby-based XSS tool, and this time, a full change occurred during the process of porting with golang!!! and created it as a new project. The basic concept is to analyze parameters, find XSS, and verify them based on DOM Parser. I talk about naming. Dal(달) is the Korean pronunciation of moon and fox was made into Fox(Find Of XSS).
