Comparing HTTP/3 vs. HTTP/2 Performance

We announced support for HTTP/3, the successor to HTTP/2 during Cloudflare’s birthday week last year. Our goal is and has always been to help build a better Internet. Collaborating on standards is a big part of that, and we're very fortunate to do that here.

Even though HTTP/3 is still in draft status, we've seen a lot of interest from our users. So far, over 113,000 zones have activated HTTP/3 and, if you are using an experimental browser those zones can be accessed using the new protocol! It's been great seeing so many people enable HTTP/3: having real websites accessible through HTTP/3 means browsers have more diverse properties to test against.

When we launched support for HTTP/3, we did so in partnership with Google, who simultaneously launched experimental support in Google Chrome. Since then, we've seen more browsers add experimental support: Firefox to their nightly builds, other Chromium-based browsers such as Opera and Microsoft Edge through the underlying Chrome browser engine, and Safari via their technology preview. We closely follow these developments and partner wherever we can help; having a large network with many sites that have HTTP/3 enabled gives browser implementers an excellent testbed against which to Continue reading
