Which chat to choose for site users?

Question

Chats

Hello!

I'm looking for a conference widget for site visitors, I considered chatbro - good, but unplanned tech often takes place. work at the most inopportune moment.
It is desirable that he be able to authorize without being tied to third-party services (just enter a nickname and log in).

Or, if there are no such ready-made services, tell me, please, can there be any starting points on the github?
