neqo VS quiche

Neqo (Mozilla) and Quiche (Cloudflare) both implement QUIC and HTTP/3. I believe they are both developing an implementation of WebTransport.

neqo

Mozilla has a Rust QUIC implementation (one of three good ones in Rust) https://github.com/mozilla/neqo

I'm not sure why it's not used here.

As an code hobbyist I'm working on an opensource project where I would be happy to use QUIC. I did a little research and found Quinn and Quiche but also the Mozilla's implementation for which I couldn't find crate Neqo.

Is it possible to compile quicly cli (referenced in the blog post) with musl instead of glibc. I had to add signal.h and it then compiled successfully but I got illegal instruction segfault when executing cli.

There are a few Rust alternatives for QUIC. Anyone tried them and have comments.

The reason is the need to have total flexibility (control). [0]

I reckon to make it as painless as possible to integrate it into Firefox. Also probably a tiny bit of not-invented-here syndrome too :)

The title of this post puts emphasis on "written in C", making me wonder when this would ever be a desirable feature, given that more secure implementations are available, and can be integrated into old C projects just as easily.

No need to rewrite everything from the ground up: https://github.com/cloudflare/quiche#curl

The issue is dead silent too!

Even though Oxy is a proprietary project, we try to give back some love to the open-source community without which the project wouldn’t be possible by open-sourcing some of the building blocks such as https://github.com/cloudflare/boring and https://github.com/cloudflare/quiche.

They’ve been on the Rust train since at least 2019. Just look at projects like quiche, wrangler, and boringtun

It's more like Cloudflare forked nginx a long time ago, and is meanwhile in the very slow (like, decade-long) process of replacing it entirely.

The Cloudflare Workers Runtime, for instance, is built directly around V8; it does not use nginx or any other existing web server stack. Many new features of Cloudflare are in turn built on Workers, and much of the old stack build on nginx is gradually being migrated to Workers. https://workers.dev https://github.com/cloudflare/workerd

In another part of the stack, there is Pingora, another built-from-scratch web server focused on high-performance proxying and caching: https://blog.cloudflare.com/how-we-built-pingora-the-proxy-t...

Even when using nginx, Cloudflare has rewritten or added big chunks of code, such as implementing HTTP/3: https://github.com/cloudflare/quiche And of course there is a ton of business logic written in Lua on top of that nginx base.

Though arguably, Cloudflare's biggest piece of magic is the layer 3 network. It's so magical that people don't even think about it, it just works. Seamlessly balancing traffic across hundreds of locations without even varying IP addresses is, well, not easy.

I could go on... automatic SSL provisioning? DDoS protection? etc. These aren't nginx features.

So while Cloudflare may have gotten started being more-or-less nginx-as-a-service I don't think you can really call it that anymore.

(I'm the tech lead for Cloudflare Workers.)

Ask Cloudflare why they use HTTP/3 and QUIC https://github.com/cloudflare/quiche.

Cloudflare has used rust for multiple projects in the past such as their QUIC/HTTP3 implementation Quiche and a WireGuard implementation BoringTun.
