Technology Website Speed Test
Measure approximate load time for a website in your browser. Many sites block direct fetching, so this is an approximate test, not a full audit.
Frequently asked questions
Is this a full speed audit?
No. This measures how long a no-cors fetch takes from your browser. A full audit needs a server tool like PageSpeed. If a site blocks fetching, it shows that clearly.
