Where can I get a web chat engine?

Question

CMS

Hello!
The situation is this, I created a site for myself, it weighs 1mb +/-, and the hosting itself gives 365mb! The remaining 360MB has nowhere to go, the idea came to create a chat!
About 10+/- years ago, for the sake of interest, I set up different CMS and also set up a chat on my PC, by querying Google, you could find a chat and set it up!
Now Google does not find anything worthwhile, only support chats.
Please tell me, easy and free chat!

Answer 1

Hello.
There is a good web chat between users for sites. Works as SAAS (cloud service). There is also a connection option based on Self-Hosted. Best integrated with WordPress. But there are other integrations as well.
The free version has a text chat between users (group and private) and a built-in online consultant function.
There are also file sharing functions, video calls and others.
