The 2,185 GitHub stars signal real adoption in the pentesting community, and the free pricing removes budget friction for red teams already stretched thin. Skip this if you need automated, continuous scanning of production apps; xssor2 is a manual testing accelerator, not a web application firewall or SAST replacement.
