"Invaluable if you do web development"
5/5
What do you like best about Progress Telerik Fiddler?

This tool is invaluable if you are doing any kind of web development. In particular, we work on enterprise services being called by many different processes, and it is not always clear what a process calling our services is actually sending. Fiddler allows us to capture messages going in and out, and debug exactly what is happening when a consumer complains of a problem. Review collected by and hosted on G2.com.

What do you dislike about Progress Telerik Fiddler?

It can be a little complicated to get Fiddler to capture the traffic you want, especially if proxies are set up in a non-standard way, or if traffic is being filtered or massaged by corporate security software. However, with some effort, we were able to overcome these issues. Review collected by and hosted on G2.com.

"Excellent tool for working with network traffic"
4.5/5
What do you like best about Progress Telerik Fiddler?

Fiddler has the ability to intercept https, and I can also intercept traffic from a smartphone via my computer acting as a proxy on the same network. This is immensely helpful for mobile app development.

Also, in the Composer feature, the request and response headers are shown accurately, unlike Postman which sometimes inserts headers automatically because it is based on Chrome's web engine. Review collected by and hosted on G2.com.

What do you dislike about Progress Telerik Fiddler?

Sometimes when https network traffic interception is enabled, the network on my Windows machine stops working completely if Fiddler is left open for prolonged durations. This is an annoyance since Fiddler is not the first suspect one would think of closing.

Also, the root certificate in the trust chain it inserts for https interception is not trusted by other parties, so some specific types of network calls may simply fail.

One feature I wish Fiddler had was easier population of headers when composing http requests via a drop-down menu or something similar, instead of having to hand-type the full content. Review collected by and hosted on G2.com.

"Fiddler is an absolute must-have tool for web development"
4.5/5
What do you like best about Progress Telerik Fiddler?

At its core, Fiddler allows the developer to capture web requests/responses in a web application environment. It allows the developer to pinpoint possible issues between the client & server.

Fiddler also has many other features that I haven't really messed with much: Ability to record & playback network traffic (ie. for testing purposes), ability to introduce artificial delays to simulate slower network speeds, etc. Review collected by and hosted on G2.com.

What do you dislike about Progress Telerik Fiddler?

At the moment, I can't think of anything I dislike about the software -- they've done a great job with it. It definitely meets my needs. Review collected by and hosted on G2.com.
