"Essential Debugging Tool with Easy Setup"

4.5/5

What do you like best about Progress Telerik Fiddler?

I like how Progress Telerik Fiddler makes it possible to block multiple hosts so they don't show up in the logs viewer, which is really helpful. The global search function across headers, request body, and response body saves me a lot of time, especially when some websites have so many network calls due to ads. This is useful for testing with my Android apps as well. Just being able to filter or block the incoming requests from ad websites and clean up the data view is fantastic. If I need to search for something specific, I can easily use a search and find it because Fiddler decodes the encoded body. Plus, the initial setup of Progress Telerik Fiddler was very quick and easy. Review collected by and hosted on G2.com.

What do you dislike about Progress Telerik Fiddler?

When I try to run it in an emulator by configuring the proxy in Android, most of the apps don't work. It has no Frida bypass or root bypass for testing my Android app, as my app has encryption, so I want to do critical security testing. Review collected by and hosted on G2.com.

"Web debuger and beyond"

5/5

What do you like best about Progress Telerik Fiddler?

Fiddler gives you the possibility to not only inspect requests and responses with all the details (headers, body and representing content in several formats) but also to use breakpoints and modify the entire response or add scripting to alter or inject content Review collected by and hosted on G2.com.

What do you dislike about Progress Telerik Fiddler?

Often it requires to explicitly decode the response body by clicking on the yellow bar in the response inspector panel. It would be good to have some automatic decoding or setting to configure this behavior. Review collected by and hosted on G2.com.

What problems is Progress Telerik Fiddler solving and how is that benefiting you?

Fiddler acts as a proxy so you can see all the traffic from a web browser and analyze each individual request, for example to a given website on the Internet, but it also allows you to inspect network calls made by other processes in your computer. This way you can easily understand what is happening, what parameters are sent and troubleshoot issues of several kinds (performance, wrong data, etc.) Review collected by and hosted on G2.com.
