The ECSY Developer Tool Panel is a free Chrome add-on developed by Mozilla Mixed Reality. It is designed to enhance the debugging capabilities of the browser developer tools by adding ECSY-specific features.

Once installed, the ECSY Developer Tool Panel creates a new tab called "ECSY" in the browser's developer tools. This tab provides a dedicated space for ECSY-related debugging and inspection. Additionally, a toolbar icon is added, which dynamically highlights when ECSY is detected on the current tab, making it easy to identify and access the ECSY-specific features.

For developers using ECSY, this tool panel offers a convenient way to analyze and debug their ECSY-based projects directly within the browser. It provides valuable insights and tools to streamline the development process and improve overall efficiency.
