About Performance Checklist
Performance Checklist is an open source GitHub repository containing a checklist of front-end performance practices for web pages. It is organized into sections on HTML, CSS, fonts, images, JavaScript, performance tools and references. Each rule includes an explanation of why it matters and how to address it, along with links to tools, articles or videos for further reading. Items are marked with one of three priority levels to help decide what to address first.
The repository is a set of guidance, not software that measures a site. Testing and monitoring are performed with the third-party tools it lists, such as PageSpeed Insights, WebPagetest and Lighthouse. The available text covers the HTML section and the tools list, so this entry does not describe the CSS, font, image and JavaScript rules in detail.
