Cloudflare Calls: millions of cascading trees all the way down

Cloudflare has launched its open beta version of Cloudflare Calls, a platform that enables developers to build real-time audio/video applications using WebRTC. The platform abstracts away the complexity by turning the Cloudflare network into a singular SFU (Selective Forwarding Unit). This allows for more efficient data transmission and improved scalability as the number of participants increases. Cloudflare Calls is currently available at no cost, with plans to charge $0.05 per real-time gigabyte starting from May 15, 2024. The platform supports standard WebRTC APIs and acts like just another WebRTC peer, making it ideal for building new WebRTC apps or supplementing existing infrastructure.
