Short answer (2026-11-11): no Linux distribution ships HTTP/3 for Apache httpd. nginx with HTTP/3 is in AlmaLinux 10 (RHEL 10), the nginx 1.26 module stream of AlmaLinux 9, Ubuntu 26.04 and 26.10 and Debian 13, but not in Ubuntu 22.04 or 24.04, RHEL 8 or Debian 12. curl with HTTP/3 is only in Debian 13. The table below lists every currently supported release, with a source for each number.
We checked each value on 2026-11-11 in the distributions’ own package indexes (AlmaLinux repository metadata, Launchpad, Debian) and, for HTTP/3 and Brotli, in the packaging build files. AlmaLinux is a 1:1 rebuild of RHEL, so its versions are the RHEL ones (RHEL 8.10, 9.8, 10.2).
Key findings
- Apache httpd HTTP/3: none of the 9 releases has it. There is no mod_http3 package in any distribution.
- nginx HTTP/3: AlmaLinux 10 (1.26.3), AlmaLinux 9 nginx:1.26 stream, Ubuntu 26.04 (1.28.3), Ubuntu 26.10 (1.30.4), Debian 13 (1.26.3). Not in AlmaLinux 8, Ubuntu 22.04, Ubuntu 24.04 or Debian 12.
- nginx Brotli module: Debian 12 and 13, Ubuntu 24.04 and later (universe). None in RHEL/AlmaLinux.
- curl HTTP/3: only Debian 13. Ubuntu 26.04 and 26.10 build curl without ngtcp2 and nghttp3.
- OpenSSL: from 1.1.1k (AlmaLinux 8) and 3.0.2 (Ubuntu 22.04) to 3.5.x (AlmaLinux 9/10, Ubuntu 26.04, Debian 13) and 4.0.3 (Ubuntu 26.10).
- Apache mod_brotli is built in every release.

nginx: the default package; + lists the other module streams on AlmaLinux 8 and 9. The last row is for comparison: the CodeIT packages for the releases that do not have HTTP/3.
What this means for an LTS server
- On RHEL 8/9, AlmaLinux 8/9 and Ubuntu 22.04/24.04 there is no distribution nginx with HTTP/3 except the AlmaLinux 9 nginx:1.26 stream, and no Brotli module on RHEL-family.
- Apache httpd has no HTTP/3 in any distribution. The packaged way is mod_http3: Apache HTTP/3 guide.
- For nginx with HTTP/3 and Brotli on the LTS releases: NGINX HTTP/3 and Brotli guide.
- For a newer OpenSSL next to the system one: OpenSSL with QUIC guide.
Method
- Releases: every release that is supported on 2026-11-11: AlmaLinux 8, 9, 10; Ubuntu 22.04, 24.04, 26.04 LTS, 26.10; Debian 12, 13.
- Versions: AlmaLinux BaseOS and AppStream x86_64 metadata (newest build); Ubuntu: highest published version in the release, -security and -updates pockets (Launchpad); Debian: highest in the suite, -security and -updates.
- HTTP/3 and Brotli: from the packaging build files (nginx.spec, debian/rules) of the published version:
--with-http_v3_module, Brotli module packages, curl--with-ngtcp2/--with-nghttp3or OpenSSL QUIC. - Limits: some build files are one upload older than the archive. Repository metadata links change with each repository update.

FAQ
Which Linux distributions have nginx with HTTP/3?

Does any distribution ship HTTP/3 for Apache httpd?
No. None of AlmaLinux/RHEL 8-10, Ubuntu 22.04-26.10 or Debian 12-13 has mod_http3. The CodeIT repository packages mod_http3 0.0.77 for EL 7-10 and Ubuntu 22.04/24.04.
