Hello, friends. In this post, you will learn how to install Zulip on Debian 11.

For those who don’t know, Zulip is an open-source application for enterprise chat and distributed teams. You could say it’s a solid alternative to Slack and even Microsoft Teams.

The server-side code is written in Python using Django, which gives you an idea of its robustness. On the client side we have versions for Linux, Windows, macOS, Android and iOS, and an integrated web interface is also provided.

Zulip is quite secure and has all the features to be considered one of the best in its field. Let’s install it.

Some preliminary considerations

To complete this tutorial, we need a valid domain name, without this we will not be able to proceed. In addition to this, you need to know approximately what type of server you require.

Usually, the measurements are done for every 100 users, where you will need a server with at least 2 GB of ram and 2 CPU cores. However, the more, the better and the more user capacity.

In addition to this, you require a user with root privileges or sudo access.

With this in mind, we can get started.
