OWASP Live Detector is a free Chrome extension designed for developers to enhance frontend security by identifying potential misconfigurations aligned with OWASP Top 10 guidelines. It operates directly within the browser, providing real-time analysis of HTTP response headers, DOM structure, and network behavior. Key features include detection of unsafe Content Security Policies, clickjacking vulnerabilities, mixed content issues, and insecure form handling, making it a valuable tool for maintaining secure web applications.

This extension ensures that all security assessments are conducted locally, meaning no data is collected, stored, or transmitted externally, thus prioritizing user privacy. By focusing on critical client-side security risks such as token leakage in URLs and heuristic patterns for DOM-based XSS, OWASP Live Detector equips developers with actionable insights to mitigate security threats effectively.
