This article shows you how to enable HTTP/3 for a website that uses Cloudflare.

Why HTTP/3?

HTTP/3 is the third major version of the Hypertext Transfer Protocol that will replace HTTP and HTTP/2 in the future. It can accelerate your website as well as make it more secure.

Check if your website using HTTP/3 or not

There are several free online tools that can help you check whether your website is using HTTP/3 or not. I strongly recommend these ones: Geek Flare H3 Testing Tool and HTTP3Check.

Enable HTTP/3 For Your Site With Cloudflare

1. Log in to your Cloudflare account then select the website/app you want to enable HTTP/3 on. Click on the “Network” button to continue.

2. Turn on the switch in the “HTTP/3 (with QUIC)” section.

Note that at this time, only a few new versions of the major browsers (Chrome, Safari, Firefox, Edge) support HTTP/3.
