Agora provides best costmization for the devopler as per the need and appliction development , also provides security while realtime and senstive communication, i can configure the agore with any application for the video calling for the live streaming. Whiteboard feature works like a charm. i use this tool multiple time and also customer support is very responsive.

Agora SDKs are always my go-to because the documentation makes them easier to integrate and customise in my Unity applications

It's great to get such quality audio and video services at such low prices. You can easily integrate it on web and mobile platforms.
