CST VerdictBased on our analysis of available product data, here is our conclusion:
Penetration testers who need to quickly validate XSS vulnerabilities in client-side filtering and WAF bypasses should use xss2png. The tool embeds payloads directly into PNG metadata, bypassing input validation that flags obvious script tags; this approach catches a specific class of filter evasion that text-based payload lists miss. Skip this if your team relies on commercial proxy tools like Burp for payload generation, since xss2png solves a narrower problem and requires manual integration into your testing workflow.
Penetration testers running frequent manual assessments against web applications will find XSSer's value in its speed; it automates the tedious work of fuzzing multiple XSS vectors across different contexts, cutting testing cycles from hours to minutes. The tool generates payloads for DOM-based, reflected, and stored XSS variants automatically, which matters when you're working through dozens of endpoints in a single engagement. Skip XSSer if your team needs post-exploitation capabilities or integrated remediation workflows; it's a lightweight scanner that finds the hole, not one that helps you map the broader attack surface or manage the fix pipeline.
