XSSer

XSSer is the tool we'd reach for when an XSS assessment requires lots of payload variation, filter-evasion testing, and detailed verification. Its large collection of attack vectors, multiple injection points, crawler support, DOM testing, WAF-oriented techniques, and reporting make it considerably more than a basic reflection scanner. It's powerful but also more complex than necessary for simple cases, so we'd reserve it for deeper XSS testing where bypasses and unusual injection contexts matter.
