Are these tools really free?

Yes. Every tool on this page is free to use and needs no account and no email address. There is a fair use rate limit so one visitor cannot monopolise the regions, and nothing else is metered.

Why do you run these tools at all?

Because we run the infrastructure they test. The same five regions that answer these checks also serve our hosting, so a tool that measures the network is a tool that measures us. If a route is slow from Sydney, we would rather you could see it than take our word for it.

Do the tools store what I look up?

The checks are not tied to an account and the results are not kept as a history. Rate limiting counts requests per connection to stop abuse, and that count is not associated with the target you tested.

Which regions do the tests run from?

Cape Town in South Africa, Frankfurt in Germany, St Louis in the United States, Singapore, and Sydney in Australia. Those are the same five cities our hosting runs in, so what you measure is the network your site would actually use.

Do the tools need JavaScript?

The tests are started in the browser, so yes they need JavaScript. They load no third party scripts and no trackers, and the whole tool script is a few kilobytes with no framework behind it.

Tools.

The same checks our own engineers run, from the same five regions that serve our hosting. No account, no email, no upsell at the end.

Why they exist

We run the network these tools test.

Five regions, one answer

Every check can run from Cape Town, Frankfurt, St Louis, Singapore or Sydney. Those are our hosting cities, not rented probe locations, so the numbers describe the path your site would really take.

Nothing to sign up for

No account, no email, no captcha wall and no report emailed to you afterwards. Run the test, read the answer, close the tab. The tool is the offer.

How to use them together

A slow site, in the order worth checking.

1. Is it reachable, and how far?

Start with a ping from the region your visitors use. If the average is close to the speed of light for that distance, the network is not your problem.

2. If loss or jitter shows up

Loss and jitter mean a fault rather than distance. A traceroute from the same region shows which hop it starts at, and whose network that hop belongs to.

3. If the network looks fine

Then the delay is the server itself. A server check shows the response time, the certificate and whether the site answers at all before you go looking at code.
