Type: General product inquiry    Platform: All Platforms   Last Updated: 2021/01/13 02:23:22

Agora RTC SDK provides real-time audio and video services for multiple users. The following table shows the number of concurrent channels and users supported by the Agora RTC SDK:

Channel profile SDK version Number of users in a channel Number of channels
COMMUNICATION v3.0.0 or later Up to one million users in a channel. Agora recommends limiting the number of users sending streams concurrently to 17 at most. No limit
COMMUNICATION Earlier than v3.0.0 Up to one million users in a channel. Agora recommends limiting the number of users sending streams concurrently to 7 at most. No limit
LIVE_BROADCASTING All Up to one million users in a channel. Agora recommends limiting the number of hosts sending streams concurrently to 17 at most. No limit
  • If the number of users sending streams concurrently exceeds the recommended value, each user in the channel can only see or hear a random group of users who are sending streams. For example, if 18 hosts are sending streams concurrently in a live streaming channel, each user cannot see or hear a random one of the 18 hosts.
  • In group video call or live interactive streaming senarios, Agora recommends enabling dual-stream mode and using the default setting for the low-quality video stream.
  • Agora does not provide APIs for limiting the number of users sending streams concurrently, and you can implement the limitation in your application layer.
