Realtime review
Score: 5/10Powerful SFU and TURN building blocks. Assembly required.
The breakdown explains the score. It is not an average. How to read these.
Last updated
Realtime, formerly Calls, provides WebRTC infrastructure on Cloudflare’s network. It includes a selective forwarding unit for audio and video, a TURN service for NAT traversal, and RealtimeKit as the higher-level SDK.
The TURN service is the best part. It is globally anycast, reasonably priced, and useful in almost any WebRTC system. The SFU is capable but low-level. You orchestrate tracks and sessions yourself, and the documentation assumes you already understand WebRTC.
There is a large gap between the low-level SFU and RealtimeKit, with too much left for you to work out. Examples are sparse next to established CPaaS vendors. The pricing is attractive if your team already knows WebRTC. Otherwise, expect a steep learning curve.

Counts what Cloudflare published, not what broke: time open is how long the status entry stayed open, and nothing before May 2025 is tracked at all. Incidents Cloudflare tagged against nothing but named in the title are counted too. The caveats in full.
