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 mobile testing programs or Android developers who need hands-on vulnerability labs should use InsecureBankv2 because it's free, maintained, and includes both client and backend components to practice real attack chains rather than isolated code snippets. The 1,417 GitHub stars and active contributor base signal a stable training environment that's been battle-tested by infosec programs for years. Skip this if your team needs guided curriculum or automated scoring; InsecureBankv2 is a sandbox, not a platform, and requires someone who already knows what they're looking for.
