"Fiddler"
5/5
What do you like best about Progress Telerik Fiddler?

Fiddler is one of the best tools to debug your web application. This tool will help you understand the input and output received by your web services, as well as the traffic on your application server. The best thing about Fiddler is that it easily captures all web services that failed and shows the response you received. It also helps you understand which services are triggered when any event object is clicked. This tool is open source, and anyone can download and check it. Review collected by and hosted on G2.com.

What do you dislike about Progress Telerik Fiddler?

When your Fiddler starts capturing the service, your mail service Outlook won't be able to send emails. Also, it is not that user-friendly. Review collected by and hosted on G2.com.

"A Great Debugging tool with Old Language"
4/5
What do you like best about Progress Telerik Fiddler?

The way it tracks URL navigation is accurate and fast. It also helps to debug the application directly from Fiddler. We can also use it for security testing. We get the output from various sources; if there is any error on the page, we can easily track it from Fiddler. There are many different features you can use, like the Get Post method to make different changes. There is a feature where if the link goes down, the UI shows it in red, which is a good indication to track any issue on the web page. Review collected by and hosted on G2.com.

What do you dislike about Progress Telerik Fiddler?

There are so many different features where we are not aware. The UI can be improved. Review collected by and hosted on G2.com.

"Best friend for HTTP Request Developers"
4.5/5
What do you like best about Progress Telerik Fiddler?

The Traffic Capturing is awesome. We can track the http requests of a specific website that we'd like to create a web automation bot. The https decode function allows to see what is happening in the background and provides a full view of the cookies, requests and the http response along with all stuff sent by the web server, such as JSON, XML, etc. Review collected by and hosted on G2.com.

What do you dislike about Progress Telerik Fiddler?

When the response body is very big, the frame doesn't show up everything. It's frustrating sometimes we need to export it to a notepad to see and analyse the results. Review collected by and hosted on G2.com.

"Fully Test Your Web Application With Fiddler!"
3.5/5
What do you like best about Progress Telerik Fiddler?

I like how simplistic the application is. I don't really have to do many setting changes in order to get started. Once I get my phone to connect properly to Fiddler, it's pretty easy from there. I like how you can filter out processes based on what you want. I tend to filter out the processes so that it only shows the urls that I'm browsing on my phone. Review collected by and hosted on G2.com.

What do you dislike about Progress Telerik Fiddler?

However, I wouldn't necessarily call this application intuitive. I definitely had to ask for guidance/help both online and offline. To be honest, I'm still not entirely sure how it all works. I feel like this application would be a bit better if there was more documentation on how it worked. I did find an instructional guide on how to use Fiddler with my phone. However, the instructional guide was pretty straight-forward. I would've liked it a bit more if it was more in-depth. Review collected by and hosted on G2.com.
