Actually I just built a tool to visualise this if you want to check it out:

Do they test full rendering time or only RTT? Also it would be useful to know IP addresses from which test request are being made. Tested a site hosted in Hetzner and got 135ms latency from Frankfurt which is unexpectedly high. Ping RTT from some US east networks to this site is around 120-150ms, how it shows the same latency within DE?

Just RTT - it downloads the whole webpage content (equivalent of running curl <url>)

I run the checks via AWS Lambda for now, might put it somewhere more stable like Hetzner/DigitalOcean for better accuracy.

I'm dense and just saw this. Its awesome fwiw!

If you could do something simple in the style of POSTMAN, but with less options - I'd pay fwiw. Not a lot, but if it existed - I'd want it!

Send a POST request to ${url} with ${headers} and ${body} and tell me how long it took from your servers...that'd be awesome!

That's actually a feature of the underlying platform I work on:

If it doesn't quite match what you expect I'd be happy to add additional features!

Nice, thanks for showing it!

I tested on my sass that has a CDN and got scared a little bit, but then did a second call and cache hit everywhere, thank god.
