CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams doing bulk URL reconnaissance or rapid XSS triage will appreciate extended-xss-search because it tests multiple XSS payloads per URL instead of stopping at the first match, catching bypasses that simpler finders miss. It's free and sits on 187 GitHub stars, meaning you can deploy it in a scanning pipeline without vendor lock-in or licensing overhead. Skip this if you need interactive exploitation or DAST integration with your WAF; extended-xss-search is a scanner for finding the vulnerability, not managing remediation workflows.
Developers and small security teams hunting XSS in web applications need XSSCon because it cuts through setup overhead; you run it, it finds reflected and stored XSS fast, no licensing friction. At 222 GitHub stars with consistent recent commits, the tool has proven reliable enough for teams that don't need fancy reporting or integration workflows. Skip this if your buyer is looking for a commercial vendor with SLA guarantees or needs DAST capabilities beyond XSS detection; XSSCon deliberately stays narrow.
