Advancing the state of the art of HTTP/2 to deliver a faster user experience. See why it matters and how much of a difference it can make.
Welcome to Speed Week!
Every year, we celebrate Cloudflare’s birthday in September when we announce products we’re releasing to help make the Internet better for everyone. We build new and innovative products throughout the year, and having to pick five announcements for just one week of the year is always challenging.

Code walkthrough on using Cloudflare workers to improve the performance of sites using Google Fonts. The improvements can be quite dramatic and the sample provides a real-world use case of doing streaming HTML modification in a Cloudflare Worker.
