Corporate messenger without saving history on the user's machine?

Question

Information Security

Gentlemen, experts, until recently, sat on MyChat, everything was fine and everyone was happy. Right now, bright minds have requested a new chat that will not store history on the end user's machine, but only on its server. The server is desirable under Linux. Who will say whether there are such animals?

Answer 1

Well, for example, RocketChat + a ban on installing the application + turning off caching in the bowser.

Answer 2

the largest open source with its own server and a bunch of goodies is https://jitsi.org/projects/ there are chats and video with audio and a server and support and open source

Answer 3

It seems that people write answers without reading the question :) If you want the user's computer to have no history cache, then use the Win32Next client for MyChat, it pulls everything from the server in a new way each time, into memory.
But it consumes more memory and, if you have many users, it will create a load on the server, constantly with each login.
Or WEB client.
But, of course, it's better to install rocket.chat, with a fat client for a couple of hundred megabytes, which does not work on old OSes, eats up memory, as if not in itself, in the terminal. And the support will be on you, not on the developer :)
