Jump start with Fiddler Everywhere

This blog post originally appeared on my blog QAInsights.

Recently I got the opportunity to be a part of Fiddler Insider Program to sneak peek the new features of Fiddler Everywhere and to provide feedback. I have been using Fiddler since 2010 (almost a decade) which helps me in performance test scripting. In this blog post, we will jump start the all new Fiddler Everywhere and its new features.

What is Fiddler?

Fiddler is a web debugging proxy tool for testers, security analysts, developers, and more. It is free to download for Windows OS only. It helps you to capture the requests for debugging purpose and more.

Jump start with Fiddler Everywhere

Fiddler Everywhere is a complete revamp of Fiddler from scratch and supports cross platform. Now you can leverage the features of Fiddler in Mac, Windows and Linux by using Fiddler Everywhere.

As you see in the above screenshot, Fiddler Everywhere has distraction free user interface. It's sleek and intuitive.

Create Account

To use Fiddler Everywhere, you need to create an account with Fiddler or sign in with Google account.

Apart from the major UI revamp, Fiddler Everywhere brings the new features and enhancements to the existing features in the Fiddler Classic.

As you see in the above screenshot, you can easily toggle on/off to capture the traffic.

Just beneath the Live Traffic, you could see all the controls to save, share, filter, decode, and stream.

Captured traffic information will be displayed in the table as shown below. Selecting the request will display the request and response in the right pane under Inspector tab.

Inspector will display the following information about the request.

• Headers
• Text
• Web Forms
• Cookies
• Raw
• JSON
• XML

Filtering

Filtering in Fiddler Everywhere has improvements. After capturing the requests, you can filter the results by clicking on Filter icon on the respective column.

Advanced filter can be applied by clicking on the Filter icon as shown below.

Auto Responder

Below is the screenshot of AutoResponder in Fiddler Classic where I have configured a rule where if there is a request to the image source, it will redirect to example.com.

Below is the Auto Responder in Fiddler Everywhere where you can arrange the rules, export/import the rules, toggle on/off the rules etc. It is intuitive to work with the rules and manage them.

Composer

Composer helps to validate the request by mocking them. It plays critical role in testing APIs. Below is how we use Composer in Fiddler Classic.

In Fiddler Everywhere you can add header information and parameters in Composer.

Collaboration in Fiddler Everywhere

Now you can easily share your recorded session via email in few clicks.

Settings

By default, Fiddler Everywhere listens to 8866. Right now, the Settings in Fiddler Everywhere looks simple, eventually it will be loaded with the Fiddler features.

Fiddler Everywhere Pro

Fiddler Everywhere will have a Pro plan in future. Right now, in free plan you can have only 5 shared sessions. We need to wait till Telerik announces about the Pro features and its pricing.

Fiddler or Fiddler Everywhere

I am planning to use both Fiddler and Fiddler Everywhere alternatively. My first preference is Fiddler Everywhere, because of its simplicity and intuitiveness. If the feature is not available in Fiddler Everywhere, then I switch it to Fiddler.
