Realtime

Realtime (the product formerly known as Calls) offers WebRTC infrastructure on Cloudflare’s network: a selective forwarding unit for audio/video, a TURN service for NAT traversal, and — since the Dyte acquisition — RealtimeKit as the batteries-included SDK layer.

The TURN service is the sleeper hit: globally anycast, priced sanely, and immediately useful to anyone doing WebRTC anywhere. The SFU is genuinely capable but low-level — you’re orchestrating tracks and sessions yourself, and the documentation assumes real WebRTC fluency.

The score reflects the assembly gap: between the low-level SFU and the still-integrating RealtimeKit, there’s a lot of “figure it out yourself” in the middle, and the examples ecosystem is thin compared to established CPaaS vendors. If you have WebRTC expertise in-house, the pricing makes it very attractive; if you don’t, you’ll feel alone out there.
