What's Supercharged in Fiddler Everywhere



  • Multiple Capturing Options

    In addition to the System proxy that captures all network traffic on your computer, and the Browser option that opens a clean browser instance, you can also capture traffic by triggering a Terminal process.

  • Choreographed Filters

    Specify the filter criteria to see captured sessions and save the filters with the power to re-use them each time you search for specific results.

  • Powerful Traffic Capturing

    Capture HTTP(S), including HTTP/2, WebSocket, gRPC traffic and connections that support TLS 1.3 on Windows, macOS, and Linux right out of the box with Fiddler Everywhere.

  • Nimble API Composer

    Fiddler Everywhere's API Composer makes it easy to quickly compose, test, group, and organize your API requests. You can make a new request from scratch or edit a request already captured by Fiddler Everywhere.

  • Robust Rule Builder

    Your power tool for mocking server responses, modifying traffic and simulating real-life scenarios. Create Rules based on your preferred conditions and organize them into Groups for easier workflow.
