Pingdom is super easy to use and is a great tool for optimizing websites for load time. You can get a lot of information quickly and test various configurations or changes easily.

I've been using buffer to test website load times and the results provided by pingdom is the most accurate ones i've ever come across.

I have used this program for years, going back to when I was employed by a web design and hosting company. It's a relatively simple app, to the point that just about anyone can use it. I have used it to gain analytics on website traffic as well as determine the reasons for crashes or point developers and engineers in the right direction.

I use this for a few days and did not like it.

Easy and straightforward to set up, in the same subscription you have everything you need to monitor your websites
