We are a small team of 5 currently using Slack for communication, but we're looking to switch to a self-hosted or more privacy-focused platform. We've found options like Matrix, Zulip, Mattermost, and others, but we're not sure which one to choose. A lightweight solution that consumes fewer server resources and supports Docker would be ideal for us.

Some people have suggested using Element without self-hosting, but we're unsure if that's a good idea. We definitely don't want to use Discord. Any suggestions would be appreciated!
