Localhost Cookie Sync is a free Chrome add-on developed by Brett Merrifield. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools.

The program allows users to sync cookies from a domain to their localhost. This can be particularly useful for developers who want to keep certain cookies, such as authentication tokens, synced to their local development environment. By syncing cookies, developers can easily test and debug their applications without the need to constantly log in or manually set cookies.

Localhost Cookie Sync provides a convenient and efficient way to manage cookies between a domain and localhost, streamlining the development process. With its user-friendly interface and seamless syncing capabilities, it is a valuable tool for developers working on web applications.
