Website speed test

We load the page once from our servers on a fresh connection and time each step, so you can see where the time goes.

Good to know

What's a good time to first byte (TTFB)?: Under 200 ms is excellent and under 600 ms is fine. Above that, the server is slow to build the page: add caching, speed up database queries, or use a faster host or a CDN.
Why is DNS or TLS slow?: Slow DNS usually means a slow DNS provider or a long CNAME chain. TLS takes longer over long distances; a CDN close to your visitors cuts it down.
Is this the same as a full page load?: No: it measures the HTML document only, not images, scripts or rendering. It's the part your server controls, and the first thing that has to be fast.

Checking by hand only tells you about right now. Spot Downtime checks your sites around the clock and alerts you by email, Slack or Discord.
