CST VerdictBased on our analysis of available product data, here is our conclusion:
AppSec teams running Burp Suite who want to accelerate reflected XSS discovery without manual regex writing should evaluate Rexsser. The plugin extracts keywords from HTTP responses and tests them automatically, cutting the time spent on pattern matching during active scanning; at 75 GitHub stars and free pricing, it's low friction to pilot alongside existing Burp workflows. This is not a replacement for a full DAST platform,it's a focused XSS hunter that works within your existing tool, so teams expecting broader vulnerability coverage or supply chain scanning should look elsewhere.
Frontend security teams hunting DOM XSS in single-page applications should use DOMdig because it combines static and dynamic analysis with fuzz testing to actually exploit vulnerabilities instead of just flagging suspicious patterns. The free pricing and 415 GitHub stars mean low friction for teams already living in CI/CD pipelines, though you'll need developers comfortable reading and acting on JavaScript-specific findings. Skip this if you need a full SAST/DAST platform covering multiple vulnerability classes; DOMdig does one thing and doesn't pretend otherwise.
