Which service of an online consultant with support would you recommend to install on your server?

Question

Computer networks

Good evening.
The task was for me, as a developer, to select an online consultant for the client, with the ability to put it on my server.
Now Jicosite, Siteheart are often used, but they are all in the cloud.
The client wants all the data of visitors, visits to the site, chats to be stored on his server, and not somewhere, from someone.
In terms of language, it doesn't matter. Better even if in English.
