"Fiddler is a good tool for web debugging. Fiddler is used to log all HTTP traffic"
3.5/5
What do you like best about Progress Telerik Fiddler?

I am using this software from 2 years. We can use Fiddler for performance testing, HTTP/HTTPS traffic recording, web debugging, security testing. We can easily extend Fiddler using the .NET network. Fiddler exposes the cache-control and expires headers for you to quickly evaluate if your application is receiving and sending back to the web server. Fiddler guarantees minimum transactions between the server and your application. Review collected by and hosted on G2.com.

What do you dislike about Progress Telerik Fiddler?

Sometimes I face difficulties when I connect to Android devices. Sometimes requests are missed in the server. Interface is good but more to work on filters. Review collected by and hosted on G2.com.

Creating auto-responses can be tough. I haven't really tried to look for documentation from Telerik on some of the advanced options except for when I'm looking for something really specific (testing for 500 error responses). Review collected by and hosted on G2.com.

"Tried several alternatives and still using it"
4.5/5
What do you like best about Progress Telerik Fiddler?

Fiddler has the most comprehensive support for HTTP request spoofing/sniffing. I've tried various alternatives, and there is always some subset of features missing in the competition. I now use a mac for work, and installed a windows VM just for fiddler. Review collected by and hosted on G2.com.

What do you dislike about Progress Telerik Fiddler?

Unfortunately, the mac version of fiddler is finicky. I prefer using a windows vm for fiddler. Review collected by and hosted on G2.com.
