Test Agent Settings

The Test agent is the synthetic browser that we use to visit your pages and run Lighthouse reports with.

You can choose between 11 different geographical locations you want the agent to run from. It makes most sense to choose a location where most of your real traffic come from so you don't introduce artificially long latency because the test agent is too far away from where your website is hosted.

HTTP Headers

In some rare cases you may want to control the HTTP headers used in the request to your website. Maybe you're testing a non-public website that requires a custom HTTP Header before it can be viewed. In that case, add the HTTP headers in this format, separated by a line break:


An example:


Note that any existing HTTP headers (such as the User-Agent) will be overwritten.
