Profile SDK Version Scale Number of Channels
COMMUNICATION v3.0.0+ 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 recommend value, all users in the channel cannot hear the voice or see the video of some users casually. For example, with the SDK of v3.0.0, all users cannot hear the voice or see the video of a host casually when 18 hosts are sending audio and video streams concurrently in the channel.
  • When the downlink network bandwith is limited, users may encounter some issues, such as audio or video freezes, and high latency.
  • In group video call or live interactive streaming senarios, Agora recommends enableing dual-stream mode and using the default setting of low-quality video stream.
  • Agora does not provide APIs for limiting the number of users sending streams concurrently, you can implement the limitation in your application layer.
