https://tools.keycdn.com/performance – Performance (TTFB)
https://webspeedtest.cloudinary.com/ – Images
https://gtmetrix.com/ – Performance
http://nibbler.silktide.com/ – Code, SEO
https://tools.pingdom.com/ – Performance, Code
https://developers.google.com/speed/pagespeed/insights/ – Code, Performance, Mobile
https://www.dareboost.com/en/home – Quality, Code, Performance (only 1 test without account, 5/month with free account)
