capo.js is a tool that analyzes the ordering of elements in an HTML document's <head> to identify elements that may hurt perceived page performance. It ships as a Chrome/Firefox browser extension, a WordPress plugin, and an npm library with a programmatic API.
Use cases
- audit the order of elements in my page's <head> for performance
- find out which head elements are slowing down page rendering
- analyze head element ordering programmatically in Node.js
- automatically sort the <head> of a WordPress site
- diagnose why my page feels slow to load
- check if critical CSS and scripts are loaded early enough
When to choose
- you want to optimize perceived page load performance via head element ordering
- you need a quick browser extension to inspect any page's head
- you want a programmatic API to lint head ordering in CI or tooling
When to avoid
- you need general-purpose performance profiling beyond head ordering
- your performance issues are unrelated to document head structure
