This repository is a curated list of resources for web performance optimization, often abbreviated as WPO. Web performance optimization is the practice of making websites load and respond faster, which matters both for user experience and for how well pages rank in search engines. The list covers tools, articles, books, talks, blogs, and documentation across a wide range of subtopics.

The collection is organized into categories. There are sections for tools that analyze how fast a page loads, tools that monitor how an application performs over time, image optimizers, CSS and JavaScript minifiers (tools that shrink file sizes), lazy loading utilities, content delivery network resources, and more. There are also sections on Core Web Vitals, which are the specific metrics Google uses to measure page experience, including how fast the main content appears, how stable the page layout is, and how quickly the page responds to user input.

The books section includes well-known titles on browser networking, JavaScript performance, and designing for speed. The case studies section links to collections of real-world examples showing how performance improvements affected business outcomes. The documentation section links to official references like MDN, the Chrome team, and W3C specifications.

This is a reference list, not software to install or run. It is aimed at web developers, designers, and anyone responsible for the speed of a website. The list is community-maintained and accepts contributions via GitHub.
