Need a simple HTTP sniffer but don't want to fork out the $100.00 for the pro version of HTTPWatch? Well, I was in the same boat. So I made one. HTTFree allows you to query any web address and specify the domain, path, protocol and port. You get back a rundown of your request headers, response headers, the page source / response body and a list of all the page resources and how long they take to load. The last of which features is brought to you by the awesome PhantomJS project.
The live version of the project is at http://httfree.exampleapi.com
The github repo is at https://github.com/jacopotarantino/HTTPFree
Now you too can check up on a weird display bug while out to brunch!
