What chat application for my website?

Guys I hope I am in the correct section.



I am looking for a chat application to implement it to my Algo-Trading website. I don't have idea which to use or which is best. I came across RumbleTalk and Cbox but still looking for more options before I decide which to take.



Have in mind I want to be able to post youtube videos and charts into it and I also want to have option for design makeover.



Thanks!!
