    The AutoResponder feature has been updated and renamed to Rule Builder as of July 2021.

  • Collaboration

    Fiddler Everywhere is designed to keep your team in mind. You can now seamlessly save sessions, comment, and share them with your team without manually export them. Each saved session opens as a new tab in the Sessions view so that you can debug these sessions independently. You can also share your Composer collections, enabling your team members to test and use your APIs.
