Filter out specific activities

Fiddler Everywhere supports every major browser in use today: Chrome, Firefox, Safari, Edge, Opera, IE, and more. Since Fiddler Everywhere acts as a proxy, all network requests from a browser or app are routed through it. Seeing too much traffic? Fiddler Everywhere can filter out the noise, while allowing you to save particular filter options and limit your view to specific apps, URLs, and processes.

Fiddler Key Features

Live Traffic Inspection

Inspect and debug traffic from macOS, Windows, and Linux systems (as well as iOS and Android devices). Ensure the proper cookies, headers, and cache directives are transferred between the client and server. Supports any framework, including .NET, Java, Angular, React, Vue.js, and more.

Rule Builder

Fiddler Everywhere’s Rule Builder enables you to identify/intercept traffic and have the debugging proxy respond on behalf of the remote server. Create rules that automatically trigger a response by returning a previously captured session, status code, local file, and so on — all without touching the server.

Save and Share Sessions

Network sessions captured by Fiddler Everywhere can be saved into workspaces and replayed later. These same sessions can also be shared (and commented on) with your teammates within the Fiddler Everywhere UI. The Fiddler Everywhere client provides a secure method for collaboration to boost productivity.
