Metered RTC voice and video API
Free tier + paidRealtime, comments & collabagora.io
What it is
Global realtime engagement platform selling voice, video, interactive live streaming, signaling and chat as metered minutes across its own software-defined network. Video is priced by resolution tier, so standard definition costs materially less than Full HD or 2K. Notably strong routing and presence across Asia, including mainland China.
Why it earns a slot
Cheapest headline per-minute rate among the large video vendors and the broadest platform SDK coverage, including Unity and Electron. Its interactive live-streaming mode handles one host plus thousands of viewers, which a plain SFU room cannot.
Know before you commit
Minutes are aggregated and priced by resolution tier, so a 1080p multi-party call bills at several times the advertised standard-definition rate — read the resolution table before modelling costs. The SDK surface is large and the docs are dense next to Daily or LiveKit.
