Brief: Rocket.Chat is an open-source team communication application with features and looks similar to Slack. You are free to self-host it or opt for their managed service for a fee.

Slack is a useful and popular team communication app that potentially replaces emails for work. A lot of big and small teams use it, even we at It’s FOSS relied on Slack initially.

However, we needed a good open-source alternative to Slack and that’s when we came across Rocket.Chat. Sure, there are several other open-source slack alternatives, but we opted for Rocket.Chat for its similarity with Slack and ease of deployment.

Can’t self-host Rocket.Chat? Let us help you

Deploying open source applications and managing Linux servers takes some expertise and time. If you lack either but still want to have your own instance of open source software, we can help you out.
With our new project, High on Cloud, you can leave the deployment and server management part to us while you focus on your work.

On Linux, Rocket.Chat is available as a snap and a Flatpak package. You can go through our guides on using snap or Flatpak on Linux to get started.

I would recommend installing it as a Flatpak (that’s how I use it) to get the latest version. Of course, if you prefer to use it as a snap package, you can go with that as well.

In either case, you can explore the source code on their GitHub page if you need.

My Thoughts on Using Rocket.Chat

I’ve been using Rocket.Chat for quite a while now (for our internal communication at It’s FOSS). Even though I was not the one who deployed it on our server, the documentation hints at a swift process to set it up on your server.

It supports automation tools like Ansible, Kubernetes, etc and also gives you the option to deploy it as a docker container directly.

You will find plenty of administrative options to tweak the experience on your instance of Rocket.Chat. It is easy to customize many things even if you are not an expert at self-managed projects.

Personally, I appreciate the ability to customize the theme (it is easy to add a dark mode toggle as well). You get all the essential options available on smartphone as well. Overall, it is indeed an exciting switch from Slack and it should be a similar experience for most of you.
