xPanel is a free Chrome add-on developed by Fred that aims to simplify network debugging for developers. It addresses the common issue of cross-domain problems that developers often encounter when running network debugging. With xPanel, requests made locally on localhost orwill automatically support cross-domain.

One of the key features of xPanel is the addition of a new tab called xPanel in Chrome's DevTools. This tab allows developers to make network requests without worrying about cross-domain issues. It provides a convenient and easy-to-use interface for testing and debugging network requests.

In addition to supporting cross-domain requests, xPanel also offers other useful features. It includes CORS Dev, which helps developers manage and configure Cross-Origin Resource Sharing (CORS) settings. It also functions as a DevTools plugin, meaning it can be used not only in Chrome but also in Electron.

xPanel is a valuable tool for developers who frequently encounter cross-domain issues during network debugging. It simplifies the process and provides an intuitive interface for testing and debugging network requests. Best of all, it's completely free to use.
