The First Media over QUIC CDN: Cloudflare

Summary

published 8/21/2025 The First MoQ CDN: Cloudflare 🚨 It’s finally happening! 🚨 Cloudflare has just announced their Media over QUIC CDN! It’s an official product, and you can test MoQ on their massive, anycast network. Try it out, and convince your boss’ boss that the writing is on the wall. If you’ve been living under a rock, MoQ is an up-and-coming standard for live media, aiming to supplant WebRTC, HLS/DASH, and even RTMP/SRT as the one to rule them all. And now Cloudflare wins the award for the first CDN offering! Your prize is a blog post. You’re welcome mega-corp. Also, while you’re here, some shameless self-promotion: I just soft-launched hang.live. Check it out if you want to see the cringe cool stuff you can do with MoQ. What’s available now?
