Calibre, the website performance testing app, launched a one-off Website Speed Test page anyone can use for free. This is nice it requires no special knowledge to use (anyone can type in a URL), the test can be run from significant geolocations (that probably aren’t where you live), and the test result is saved and can be shared.
webpagetest.org is the classic in this space. Both are trying to sell you more advanced services. Just a matter of which you find more useful.
