I like what Zulip tries to be in theory (the "topics" feature is really great), but there are two knocks against it, in my opinion:

1. They do not support self-hosting the code on a system with anything else hosted on it. You are strongly recommended to dedicate a server (VPS, Docker, whatever) to your Zulip installation. You can try to install it on an existing server, but it is far from trivial, and doing so is unsupported.

2. As part of the installation script(s), they blindly wget code and execute it with bash. https://github.com/zulip/zulip/blob/eb676e8e508df0349662addd...
