This made the top of my list and I use it almost every day. Although it has features very similar to firebug,
it has two features that I find very useful – the ability to save the
waterfall data directly to a csv file and a stand-alone HttpWatch Studio
tool that easily loads previously saved data and reconstructs the
waterfall ( I know you can export Net data from firebug, but only in HAR
format). And best of all, HttpWatch works with both IE and Firefox. The
downside is that it works only on Windows and it’s not free.
This is everyone’s favorite tool and I love it too. Great for
debugging as well as performance analysis. It is a little buggy though –
I get frustrated when after starting Firebug, I go to a URL expecting
it to capture my requests, only to find that it disappears on me. I end
up keeping firebug on all the time and this can get annoying.
This is also a Windows-only commercial tool – it is similar to
Wireshark. It’s primary focus is http however, so it is easier to use
than Wireshark. Since it sits at the OS level, it captures all traffic,
irrespective of which browser or application is making the http request.
As such, it’s a great tool for analyzing non-browser based http client
Yet another commercial tool, but considering our global presence and
the dozens of websites that need to be tested from different locations,
we need a robust, commercial tool that can meet our synthetic testing
and monitoring requirements. Gomez has pretty good coverage across the
