About the Page Speed Checklist
The Page Speed Checklist is an interactive, comprehensive guide for front-end developers aiming to achieve 100/100 performance scores. While automated tools are useful, a manual audit ensures you address the foundational architecture of your site rather than just treating the symptoms.
Features
- Structured Audit: Categories are broken down logically into Images, Web Fonts, JS/CSS, Caching, and Server configurations so you can tackle optimization methodically.
- Persistent State: Your progress is saved automatically to your local browser storage. You can safely close the tab and return later to continue your audit.
- Actionable Insights: Each checklist item includes a brief explanation of *why* it matters, and provides links out to official documentation (like MDN or web.dev) for deeper learning.
- Export to Markdown: Once you've completed your audit, click 'Copy as Markdown' to generate a formatted list. This is perfect for pasting into GitHub Issues, Pull Requests, or internal documentation.
Start from the top and work your way down. Even implementing half of these recommendations will drastically improve your Time to First Byte (TTFB) and Largest Contentful Paint (LCP).
