Website speed test API and cross-platform CLI

We have published first version of our website speed test API, and to make it easier to use we also published simple command line interface tool which uses it.

Source code for AppBeat CLI tool is written in C# on top of cross-platform .NET Core platform and is available on GitHub. Installation instructions are available on our Website Speed Test page.

For example, if you would like to test page speed from Asia you would simply run following AppBeat CLI command:

dotnet AppBeat.CLI.dll page-speed Asia

If you are adventurous enough to use our API directly, here is how to do this :)

First, you have to obtain AppBeat API Access Key which you can get for free, but you have to have AppBeat account (Sign Up here).
Then you would have to POST json message (content type should be set to application/json) to or

Posted json message should have following fields:

   "Location": "TEST_LOCATION"

Where TEST_LOCATION should be Europe or NorthAmerica or Asia.

In return you should get json response with unique test id. Then periodically call AppBeat API server (with few seconds in-between) and ask it if results are available. You do this by sending HTTP GET request to or

Test is completed when Status property in json response is not Submitted or Pending anymore (it can take up to minute or two to start your test from our submitted test que).

You can also check our C# source code of our AppBeat CLI tool which implements this logic. Relevant code is located at:
