About this tool
Enter a web address to time each stage of loading it: finding the address (DNS), connecting, the secure handshake (TLS), the wait for the first byte and the total time. Run several tests to see the spread. You also see the status code and any redirects. The times are measured from this server, not from your device, so your visitors may see different numbers.
Common questions
Where are the times measured from?
From the server that runs this tool, not from your computer. Distance and network quality change what visitors see.
What is time to first byte?
The time until the first piece of the answer arrives. It includes DNS, connecting and the TLS handshake, and shows how quickly the server starts responding.
Why do the tests differ?
Servers and networks vary from moment to moment. The median of several tests is a steadier number than a single one.
Is it free to use?
Yes. There's no sign-up for everyday use, and a free account raises the daily limit if you need more.
Do I need to install anything?
No. It works in your browser on a computer or a phone.
Is what I enter kept?
It's only used to get your result. Some public answers, such as the branches for a pincode, are kept for a while so the next lookup is quicker, but nothing links them to you.
