Rocket.Chat vs Slack: Choosing the right fit for your team

Rocket.Chat vs Slack overview

Before we start comparing Rocket.Chat and Slack category by category, let’s do an overview of both apps. 

According to their site, Rocket.Chat is the world’s largest open-source communication platform.

It lets you communicate and collaborate with coworkers, other companies, customers, and communities.

You can also create a custom messaging experience by integrating and white-labeling Rocket.Chat components and enterprise features. 

Moreover, this app allows you to extend and customize your workspace with custom apps, open APIs, powerful plugins, and webhooks.


Slack is a popular communication platform, mostly used by businesses for internal communication — but it also lets you communicate with people outside your company.

Communication is organized in spaces called channels — so you can find all people, messages, and files related to a certain topic in one place.

Slack allows you to choose when and how you want to communicate, with advanced notification options and the ability to communicate both live and asynchronously.


Here’s a side-by-side overview of the apps’ main features.

Now, let’s get into detail for each category. 

Rocket.Chat vs Slack pricing 1:0

Pricing often turns out to play the biggest role when making a decision — so, let’s start with that.

Rocket.Chat has two pricing plans: Community and Enterprise.

The Community plan is free — and it’s ideal for small teams since it offers plenty of features, including:

  • Unlimited 1:1 and group messaging,
  • End-to-end encryption,
  • Full messaging history, and more.

The Enterprise plan has the following pricing system:

  • $7 per user per month (for a minimum of 25 users), or
  • $35 per omnichannel agent per month (for a minimum of 5 agents).

With this plan, you unlock many more valuable features. 

If you need something that’s not included in the Enterprise plan, such as additional customer support or services (e.g. upgrading and scaling or data migration), you can purchase add-ons that will support all your needs.

Slack, on the other hand, is more expensive.

What’s more, starting from September 1, 2022, Slack will increase some of its prices and upgrade Free and Pro plans.

What does that mean?

  • The Free plan is still free (as you’d expect). However, instead of allowing users to see the last 10,000 messages and up to 5GB of uploaded files, it will start showing all messages and files sent in the last 90 days.
  • The Pro plan is changing from $8 to $8.75 per user per month — or, if you purchased the annual Pro subscription, from $6.67 to $7.25 per user per month.
  • The prices of Business+ and Enterprise Grid plans stay the same: Business+ is $12.50 per user per month (with the annual subscription), while the price of the Enterprise Grid plan depends on your team and its needs.

Rocket.Chat vs Slack interface 1:0

Rocket.Chat and Slack have quite a similar interface. The chat you’re in takes the majority of the screen, while on the left sidebar you can see your channels and direct messages.

Both are fairly intuitive, easy to use, and have customization options.

Rocket.Chat has a clean, minimalist look.

You can also customize the look of your Rocket.Chat server. The customizable elements involve colors, content, CSS, and Javascript.

Rocket.Chat vs Slack notifications 0:1

Many people have a love-hate relationship with notifications.

On one hand, no one wants to miss an important message.

But, hearing a familiar buzz every so often can be incredibly distracting.

That’s why it’s important to have advanced notification options in your business messaging app.

On Rocket.Chat, you can choose to get notifications for all messages, just mentions, or to receive no notifications.

If you are idle for 60 seconds on the desktop app, you will be considered away and get notifications on your mobile device.

Notifications on Slack are highly customizable. 

You can pick whether you’ll receive all notifications, some of them, or none. If you pick the first option, you’ll be notified when:

  • You get a direct message from someone
  • Someone mentions you
  • You get a reply on a thread you’re following
  • You receive a message from Slackbot

You can also decide when you’ll receive notifications, as well as activate Do Not Disturb mode when you want to immerse yourself in work.

If you’re expecting an important message but you’re not by your computer, you can choose to be notified on your mobile device.

Rocket.Chat vs Slack search 0:1

Time is money — and no one wants to spend more time looking for a specific message/file than it’s absolutely necessary. 

To be as productive as you can be, a good search option is a must.

On Rocket.Chat, every user gets unlimited access to full messaging history, even in the Free plan. 

You can search messages and apply different search filters, e.g.:

  • Messages created by you
  • Messages created by a specific person
  • Starred messages
  • Pinned messages in a channel
  • Messages that contain a link
  • Messages that have a location attached
  • Messages sent within the chosen time frame

On Slack, you can search not only through messages, but also:

  • Files,
  • People, and
  • Channels.

You can also search within documents, which saves a lot of time.

If you have a vague idea of where the message you’re searching for could be, you can also pick a time frame for your search or exclude specific channels.

When you’re working on a project, you often have to use many different apps and tools. And, for efficient and uninterrupted workflow, it helps if those apps and tools are connected.
