CST VerdictBased on our analysis of available product data, here is our conclusion:
0l4bs Cross-site scripting labs
Security teams building internal training programs or running capture-the-flag events need 0l4bs Cross-site scripting labs because it teaches XSS exploitation mechanics hands-on without requiring infrastructure setup or licensing; the 20 labs cover realistic filtering bypasses that developers actually encounter in code review. The free pricing and 334 GitHub stars signal actual adoption among practitioners, not just theoretical content. Skip this if your goal is to measure XSS vulnerability remediation across your application portfolio; this is a learning tool, not a scanner that finds XSS in production code.
Security teams building AWS-native incident response skills need CloudGoat because it's free, hands-on, and designed specifically around real misconfiguration chains rather than generic vulnerabilities. The 3,500+ GitHub stars reflect adoption by security shops serious enough to run their own labs, and the capture-the-flag format forces teams to think like attackers moving laterally through cloud infrastructure. Skip this if your organization needs managed training with compliance reporting or if you lack engineers who can provision and troubleshoot AWS environments independently; CloudGoat teaches through broken infrastructure, not polished courses.
