When Calibre analyses your site, it uses a custom analytics suite, powered by Google Chrome in a clean room environment.
Tests are conducted with cache disabled, with no other known network activity, on dedicated hardware. Our agents autoscale to meet demand, and will never leave you waiting for tests to complete.
All requests made by the Agent originate from one of our dedicated IP addresses. This can be useful if you’d like to bypass user authentication or allow Calibre to view a staging site. For tips on setting up authentication, read our guide.
