"As of September 2024, HTTP/3 is supported by more than 95% of major web browsers in use and 34% of the top 10 million websites."

Yes and, at the same time practical support within programming language standard libraries & common tooling lags way behind: https://httptoolkit.com/blog/http3-quic-open-source-support-...

You will get most of the benefits of HTTP 3 even if your app libraries run HTTP 1.1, as long as the app is behind a reverse proxy that speaks HTTP 3.

		I use HAproxy to get HTTP/3. https://www.haproxy.org/ https://haproxy.debian.net/ https://www.haproxy.com/blog/how-to-enable-quic-load-balanci...

		Yep, for example, Caddy (zero special configuration to enable HTTP 3)

A lot of servers still don't support that.

Go http webserver doesn't support http 3 without external libraries. Nginx doesn't support http 3. Apache doesn't support http 3. node.js doesn't support http 3. Kubernetes ingress doesn't support http 3.

should I go on?

edit: even curl itself - which created the original document linked above - has http 3 just in an experimental build.

It's not experimental when built with ngtcp2, which is what you will get on distros like Debian 13-backports (plain Debian 13 uses OpenSSL-QUIC), Debian 14 and onward, Arch Linux and Gentoo.

nginx do support it.

https://nginx.org/en/docs/quic.html

		And I see I was not that wrong; the module is still marked as "experimental" and not built by default. https://nginx.org/en/docs/http/ngx_http_v3_module.html

		ah okay i was wrong there, mea culpa

		The guy's point still stands - lots of popular software do not yet support http3.

Well this statement have to be precised.

caddyserver v2 supports HTTP/3 and it's an webserver written in go https://caddyserver.com/features

FYI: There is also an rust webserver which supports HTTP/3. https://v2.ferronweb.org/

		Go built-in webserver.
