Use case
Mock Network Requests
Use Fiddler Everywhere to simulate/intercept https traffic, simulate network latency or even recreate specific network scenarios
to test and debug your apps.
Simulate HTTP/S traffic
Fiddler Everywhere’s Rule Builder enables you to intercept HTTPS traffic and have the debugging proxy respond on behalf of the remote server. With Rule Builder, you can create rules that automatically trigger a response to requests by returning a previously captured session, a new status code, a local file, and so on - all without touching the server.
Simulate network latency
Rule Builder lets you create rules that simulate network latency in macOS, Windows, or Linux through which you can test the performance of your application in low/no network condition. Create rules to simulate delay in response times, drop requests, return error codes, etc.
Compose HTTP/S requests
Use Fiddler Everywhere’s Composer to manually build and send network requests. You can also right-click and clone a previously captured session, while having the option to modify request parameters if needed.
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.

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.
