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 plans stay the same: Business+ is $12.50 per user per month (with the annual subscription), while the price of the Enterprise plan depends on your team and its needs.

Since Rocket.Chat offers a variety of features with a lower price tag, it wins this round.

Pricing	Rocket.Chat	Slack
Free plan	Yes	Yes
Cheapest paid plan	$7 per user per month	$8.75 per user per month
Overall impression	⭐⭐⭐⭐	⭐⭐⭐

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.

Slack’s UI has a different aesthetic, but it’s also user-friendly and easy to navigate. 

Among other things, you can:

• Customize the sidebar, 
• Pick a theme, and 
• Add custom emojis.

In this round, it’s almost a tie. 

But, since Rocket.Chat offers more room for customization, it gets a point.

Interface	Rocket.Chat	Slack
Layout	Minimalist and easy to navigate	Simple and user-friendly
Customization	Advanced	Advanced
Overall impression	⭐⭐⭐⭐	⭐⭐⭐

Rocket.Chat vs Slack communication 1:1

• Messaging people outside Rocket.Chat
• Audio and video calls
• File sharing
• Making custom workflows
• Search option
• Unlimited chat history
• Emojis and GIFs

It’s just important to note that to access some of these features, you have to enable them in the settings.

• Organizing conversations into public and private channels
• Sharing files
• Audio and video calls
• Scheduling messages
• Creating polls
• Search option
• Editing and deleting messages
• Emojis and GIFs

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.

Obviously, Slack wins this round due to its more sophisticated notification settings.

Notifications	Rocket.Chat	Slack
Notification configuration	Basic	Advanced
Do Not Disturb	No (but, the app is customizable so you can add it)	Yes
Overall impression	⭐⭐⭐	⭐⭐⭐⭐⭐

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.

Even though Rocket.Chat offers valuable options for facilitating your searches, file search is what gives Slack a win this time.

Search	Rocket.Chat	Slack
Message and channel search	Yes	Yes
File and people search	No	Yes
Filters	Yes	Yes
Overall impression	⭐⭐⭐⭐	⭐⭐⭐⭐⭐

Rocket.Chat vs Slack file sharing and storage 0:1

Sharing documents and files is a big part of a regular workday — so, for a workday to go smoothly, file sharing should be fast and easy. 

Rocket.Chat allows you to share the following, with complete data protection:

• Files, 
• Documents, 
• Photos, and 
• Videos from your computer, device, or cloud storage.

It has unlimited messages and full message history even in the Free plan.

When it comes to storage, Rocket.Chat uses external storage.

Slack lets you share all kinds of files of up to 1GB in size — images, videos, audio files, PDF files, etc.

Different plans get you different storage options:

• Free: 5GB for the entire workspace
• Pro: 10GB per member
• Business+: 20GB per member
• Enterprise Grid: 1TB per member

Since Slack has more file sharing and storage options, it wins this round.

Rocket.Chat vs Slack integrations 0:1

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.

That’s why the more integrations the app offers — the better.

Rocket.Chat supports more than 100 integrations in 26 different categories. Some of them are:

• Communication apps — like Jitsi, Zoom, Webex, Slack, and MS Teams
• CRM and Productivity apps — like HubSpot, Salesforce, Dropbox, and Search
• Social media and chat apps — from SMS and email to Telegram, WhatsApp, Live Chat, Twitter, Messenger, etc.
• DevOps software — such as Jira, BitBucket, Bamboo, Confluence, and GitLab

Slack’s integrations are even more impressive — you can choose from 2,400+ integration options.

They are also divided into categories, for easier search.

Apart from classic app categories (such as Design, File Management, Productivity, etc.), in Slack App Directory you can find categories such as:

• Working from home apps — like Google Drive, Zoom, Trello, and Google Calendar 
• Daily Tools apps — such as Slack for Gmail, Dropbox, Box, and Google Shhets for Workflow Builder

Rocket.Chat vs Slack security 1:0

Protecting your data is crucial, especially if you’re a business. Because of that, you shouldn’t take security options (or lack thereof) lightly.
