StreamScope is a free Chrome add-on designed for developers, enabling them to capture and debug HLS/M3U8 video streams directly in the browser. This powerful tool allows users to view HLS manifests, inspect different stream qualities, and replay streams for thorough analysis. It is particularly useful for development and testing purposes, providing an effective way to ensure video streaming quality and performance.

The application operates entirely locally, ensuring that no data is sent externally, which enhances user privacy. StreamScope does not bypass any digital rights management (DRM) or content protection measures, making it suitable for educational use without compromising on security. With its user-friendly interface, StreamScope stands out as a valuable resource for anyone involved in video stream development.
