Packet Proxy is a Chrome add-on developed by wisestcoder. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This free plugin acts as a proxy for resources and requests, allowing users to modify cookies and HTTP headers.

With Packet Proxy, users can easily proxy their resources and requests, similar to other popular tools like Charles, without the need to set up a separate nginx server. This makes it convenient for developers who want to test their applications locally without the hassle of configuring a proxy server.

One of the key features of Packet Proxy is its ability to modify cookies. This can be particularly useful for solving authentication problems during local development and debugging. Instead of manually obtaining cookies from a remote server, Packet Proxy can automatically handle the authentication process.

Additionally, Packet Proxy allows users to add and modify both request and response headers. This gives developers the flexibility to set headers such as X-Forwarded-For, Authorization, Access-Control-Allow-Origin, and more.

Overall, Packet Proxy is a handy Chrome add-on for developers who need a quick and easy way to proxy their requests, modify cookies, and manipulate HTTP headers. It simplifies the testing and debugging process, making it a valuable tool for web development projects.
