Easy setup if using windows client, logging works well, able to see request details in real time which helps debugging issues faster than any other tools i've used so far (this can be handy when dealing with slow or expensive internet).
not many features yet though, need more development. easy install if needed, fast speeds for web requests recording, good platform for developing applications that use REST APIs. I liked all of my interactions with staff at fiddlersoftware inc., they were extremely helpful in answering any questions that arose during our project development phase as well their implementation services team was amazing! nothing specific there really but overall it's an awesome experience working/cooperating witheveryone involved so far has been fantastic!! i've learned alot from every interaction we had together throughout out process (from ideation till production).
