Use case

HTTP/S Traffic Recording

Fiddler Everywhere allows you to capture, inspect, monitor and replay both HTTP and HTTPS network traffic from any browser and any app.

Save and replay network sessions

Fiddler Everywhere allows you to monitor and record HTTP/S traffic, including HTTP/2 and WebSocket sessions for later play back. If needed, you can record and modify request parameters and headers for further testing. Saved sessions can also be shared with your teammates.

Filter captured traffic

Wading through hundreds of requests and responses as you capture traffic can be daunting. Fiddler Everywhere allows you to quickly filter both past and current traffic and work with saved filter options. Filter by URL, method, protocol, host, and more. You can also hide all successful “200” requests to only see errors and warnings.

Dive into session metrics

Inspecting individual sessions in Fiddler Everywhere shows you details such as network status, headers, caching, cookies, URLs, protocols, compression, redirects, and more. Right-click a session to save it for later, share with your team, create a rule from the Rules Tab, or replay in Composer.

Capture all traffic

Sometimes you need to capture *all* traffic to and from a desktop or web app. Fiddler Everywhere can step in to help you record all HTTP/S traffic that passes between your computer and the Internet, including HTTP/2, WebSocket, gRPC traffic and connections that support TLS 1.3. Even better, Fiddler Everywhere can also capture traffic from other locally running 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.
