Performance - Website Performance

Performance Op utilizes opensource tools such WebPageTest and Lighthouse to check your website's performance.

WebPageTest is an open source performance testing tool, maintained primarily by Google. It consists of one or multiple servers that act as web browsing robots, visiting websites and automatically collecting data about the experience in the form of a detailed performance report.

Lighthouse analyzes web apps and web pages, collecting modern performance metrics and insights on developer best practices.

Requirements

To run this or any other Op, install the Ops Platform.

Find information about how to run and build Ops via the Ops Platform Documentation.

This Op also requires API Key for WebPageTest.
