CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams building or testing real-time applications should use OWASP Damn Vulnerable Web Sockets to close the WebSocket blindspot in their training programs; most developers never encounter these vulnerabilities in labs because frameworks like OWASP WebGoat don't cover persistent bidirectional connections. The 356 GitHub stars and zero licensing friction mean you can spin up a shared lab environment across your entire engineering org without budget negotiation. Skip this if your team only cares about HTTP-based OWASP Top 10 coverage; DVWS is narrow by design and teaches one thing well rather than serving as a general-purpose vulnerable app.
Security teams building internal training programs or running capture-the-flag exercises need Damn Vulnerable Web Services because it's free and maintains a working lab environment without licensing friction or infrastructure overhead. The project has sustained community contributions across 456 GitHub stars and covers multiple OWASP Top 10 categories, giving practitioners real vulnerable code to dissect rather than theoretical scenarios. Skip this if your goal is learning to defend production APIs; Damn Vulnerable Web Services is deliberately broken in ways that don't map cleanly to modern cloud architectures or async service patterns.
A deliberately vulnerable web application that uses WebSocket communication to provide a training environment for learning about WebSocket-related security vulnerabilities.
An intentionally vulnerable web application containing multiple web service security flaws designed for educational purposes and security testing practice.
