This is frustratingly one-sided writing. Yeah, WebRTC has limitations, but relying on a standard buys you a lot of correctness and reduces long-term engineering cost. The fact that WebRTC is complicated does not mean it is wrong; it means real-time media over the public internet is complicated.

Also, networking is inherently stateful. NAT traversal, jitter buffers, congestion control, packet loss, codec state, encryption, and session routing do not disappear because you put audio over TCP or WebSocket. Pretending otherwise is not architectural clarity. It is just moving the complexity somewhere less visible.

You might have noticed that the author started the blog post explaining themselves:

  Like 6 years ago I wrote a WebRTC SFU at Twitch.
  Originally we used Pion (Go) just like OpenAI,
  but forked after benchmarking revealed that it was too slow.
  I ended up rewriting every protocol, because of course I did!

  Just a year ago, I was at Discord and I rewrote the WebRTC SFU in Rust.
  Because of course I did! You’re probably noticing a trend.

  Fun Fact: WebRTC consists of ~45 RFCs dating back to the early 2000s.
  And some de-facto standards that are technically drafts (ex. TWCC, REMB).
  Not a fun fact when you have to implement them all.

  You should consider me a Certified WebRTC Expert.
  Which is why I never, never want to use WebRTC again.
I think that they've done more than enough of 'trying the normal way' to be warranted in having an opinion the other way, don't you think?

Tangential, but by being that, it's also refreshingly human writing, vs the both-sidesy bullet listed AI pablum that's all around us these days.

I have zero take on the subject matter, but I like that the article had a detectably human flair.

And if it was AI written, god help us.

“How hard can it be?” the strawman asked.

It’s 2026 and teleconferencing is still such a shit show. There’s billions of dollars to be had and Zoom is at best mediocre, and it can be as bad as Microsoft Whatchamacallit. I’ve never not seen teleconferencing be a ham handed mess.

QUIC is also a standard.
