Fiddler is one of the best online tool available right now for monitoring and analyzing web traffic. In Fiddler, you can easily find out almost everything with respect to web request like Headers, Text View, Syntax View, Cookies etc. of a request. All in all, this becomes very helpful for a developer or user who is analyzing web traffic requests. Review collected by and hosted on G2.com. What do you dislike about Progress Telerik Fiddler? As every good software fiddler too has few issues as well. If used for too long to analyze web requests, fiddler becomes too slow and at times becomes unresponsive as well. Ability to selective filter requests is not available in Fiddler and can be a nice feature addition in future. Review collected by and hosted on G2.com.

I use Fiddler more than any other "helper" application that we run at work. The ease of access to the detail Fiddler providers in what's going on in my web requests goes way beyond anything else I've used. When I've exhausted all other debugging options (which is often) Fiddler always bails me out because I can see what's going on behind the scenes and along the wire. Review collected by and hosted on G2.com. What do you dislike about Progress Telerik Fiddler? While this isn't totally Fiddler's fault, I sometimes forget to close Fiddler and it gets in the way of publishing or other tasks that fail while a proxy is running. But it's easily fixed by simply closing Fiddler Review collected by and hosted on G2.com. What problems is Progress Telerik Fiddler solving and how is that benefiting you? Fiddler saves a TON of time normally spent on debugging problems that may not be visible otherwise. I've realized that without it, there are some problems I would just have never solved.

Web Developer Small-Business (50 or fewer emp.) 7/20/2018 "Fiddler Usage on Mac for REST calls" 2.5/5 What do you like best about Progress Telerik Fiddler? I was using Postman and then wanted to try Fiddler too to compare REST call response. So this is a brief review on just the REST call feature. I used Fiddler for just a basic usage and it ran the calls that I wished to test. Overall it does that task for you. I haven't tried the other features/tools or advanced features available, but it appears there are many, so I assume advanced developers are using or demanding such advanced features. Review collected by and hosted on G2.com. What do you dislike about Progress Telerik Fiddler? It wasn't intuitive to install (for Mac) users. I understand it is on BETA, so it's somewhat expected. It's also expected in general that installing things via terminal is not always straight forward, but installing a desktop app on Mac App on mac, users typically expect a one step that it would be just through Installation wizards. It required installing Mono Framework first via terminal.. but there are directions on the Telerik blog to follow. If I recall, I had a few errors trying to install Mono that I wasn't able to resolve, but eventually tried to install Fiddler anyways, and it ran. The other thing was the set up to get going also wasn't intuitive. Postman and other applications just have you post the url, the data and run. Fiddler, however had several options to enter your server information. I believe the advantage of that, is direct connection. For my purpose, I just needed to simply enter http url, info and run, so to quickly test. It is possible because I am not too familiar with all the backend configuration which Fiddler gives options to, that it is confusing for me to fill out and make use initially. I would have to further investigate if I were to continue to test REST calls, using Fiddler tools. Review collected by and hosted on G2.com. Recommendations to others considering Progress Telerik Fiddler: If you're using Fiddler to test REST calls, it does do the job. If you're an advanced user, perhaps it appears there are many options available to make use of the Application's advanced features. If you're a Mac user, just read up on the installation process and the extra steps required. Review collected by and hosted on G2.com. What problems is Progress Telerik Fiddler solving and how is that benefiting you? I needed to use Fiddler to test a few REST calls, to see if the 3rd party APIs were running, properly. I wanted to verify that it wasn't just an error in my code, or running a REST call through command line. Over all, Fiddler returned the same data so I was able to verify that it was likely not an error on my end. So I trust that I can rely on checking with applications like Fiddler, that was developed by a team of experts. Review collected by and hosted on G2.com.

Fiddler is an amazing tools I have been using for about 4 years now. It makes REST api debugging a breeze. At every rest call, just put a debugger and see the actual calls being made, with complete header and payload. And the best part it decrypts https data too (if allowed).

Fiddler rules to handle automated responses. Review collected by and hosted on G2.com. What do you dislike about Progress Telerik Fiddler? Its difficult to say, as its been helping me a lot with debugging. But a filter with specific domains might be helpful. Currently I have to search for the domain I am debugging for.

RR ravi r. Associate Software Developer Computer Software Mid-Market (51-1000 emp.) 7/12/2018 "Correctly analyzes all requests" 4.5/5 What do you like best about Progress Telerik Fiddler? We needed fiddler to know how the file uploading failed, and fiddler did it very nicely by telling the type of error. It operates in between the requests which make it very unique. Certificates can be attached very easily. It has caches analyzing which is perfect tool for getting to know if our web app behaved correctly or not. We get to know times of all requests and hence improve the api's which causes the bottleneck. Review collected by and hosted on G2.com. What do you dislike about Progress Telerik Fiddler?
