Mattermost vs Rocket.Chat pricing plans 0:1

First things first — pricing plans. 

If you need a communication and collaboration solution for a smaller team, you should consider Mattermost’s freemium version — Starter plan — which includes:

• One workspace for your team, 
• Unlimited users, channels, playbooks, and boards,
• 10GB file storage across the platform, 
• 1:1 calls with screen share option, and
• Access to your last 10,000 messages.

If your needs are greater, you can use one of the two paid plans — Professional or Enterprise.

• Unlimited workspaces,
• 250GB file storage across the platform,
• Group calls with screen share,

There’s also their Enterprise plan, which offers a more secure solution, advanced features, and compliance. 

Rocket.Chat provides three primary tiers: Starter, Pro, and Enterprise.

The free Starter plan includes essential features like unlimited messaging history, end-to-end encryption, and matrix federation for up to 25 users.

The Pro plan is designed for scaling teams and adds white-labeling rights and standard support.

For organizations with mission-critical needs, the Enterprise plan offers advanced features like Sovereign AI, Voice calling, and Attribute-Based Access Control (ABAC) to ensure maximum security.

Mattermost vs Rocket.Chat interface 0:1

User interface is an important factor in deciding which communication platform to choose. 

For an ultimate user experience, your platform of choice should be intuitive, user-friendly, and aesthetically pleasing. 

So, let’s see what Mattermost and Rocket.Chat have to offer on this front. 

We’ll start with Mattermost.

Mattermost has a clean, intuitive interface.

It offers various customization options, including choosing different themes and modifying the sidebar to your liking, for a fuller user experience. 

Aside from that, Mattermost enables support for 16 languages — a pretty convenient feature for distributed teams around the globe. 

Furthermore, Mattermost’s interface offers white labeling so you can customize fonts and on-screen text.

It’s time we check out what options Rocket.Chat’s interface offers. 

Namely, Rocket.Chat’s interface is also very clean and intuitive. 

As an open source software, Rocket.Chat allows you to customize its:

• Colors, 
• Content, 
• CSS, and 
• JavaScript. 

Furthermore, Rocket.Chat offers support for 63 languages, and improved product content in Spanish, French, German, Japanese, Portuguese, and Arabic.

Thanks to more options for customization and support for more languages, Rocket.Chat wins the medal in this round. 

Mattermost vs Rocket.Chat communication 1:0

Although both Mattermost and Rocket.Chat help you avoid team silos by offering you group messaging in private and public channels, there is an added bonus for Mattermost. 

Namely, Mattermost enables you to organize your team communication and collaboration in:

• Channels,
• Playbooks, and
• Boards.  

Mattermost has a great solution for streamlined collaboration — Playbooks — pre-built configurable checklists that make sure you and your teammates never forget your tasks or deadlines again.

Additionally, Mattermost helps you improve your workflow via Kanban boards — they enable you and your team to easily manage tasks and projects.

Let’s move on to Rocket.Chat, which also boasts a plethora of options for a more pleasant communication experience.

Among other things, this platform enables you to:

• Communicate in private or public channels, 
• Follow or unfollow threads,
• Easily share your files,
• Enjoy unlimited chat history,
• Message people outside of Rocket.Chat, and
• Share your location.

Both Mattermost and Rocket.Chat are excellent options for asynchronous communication.

However, thanks to its more developed structure for easier communication and collaboration — channels, playbooks, and Kanban boards — Mattermost takes the crown in this category. 

Mattermost vs Rocket.Chat notifications 1:0

It’s not easy to strike that fine line between being distracted by notifications and missing important messages on your communication platform of choice.

However, there is a solution — configuration of the notifications according to your preferences. 

Fortunately, both Mattermost and Rocket.Chat offer customizing options, so let’s dive into details — starting from Mattermost. 

Mattermost notifies you in cases when:

• You get a message,
• Someone mentions you,
• Someone sends a message to a channel you’re a member of, and
• Someone uses keywords you configured. 

Rocket.Chat uses secure push notifications and AI-powered conversation summaries. This allows users to catch up on long threads instantly with a single click, significantly reducing notification fatigue compared to traditional alerts.

For teams that work across time zones, an especially useful feature is the Do Not Disturb (DND) mode, which Mattermost has among its built-in options.

Rocket.Chat doesn’t offer this option, but since its notifications are customizable, you can add it.

So, since Mattermost offers a more advanced notification configuration, it is the winner in this category.

Mattermost vs Rocket.Chat search 1:0

If the communication tool of your choice doesn’t have adequate search capabilities, it may cost you your time, nerves, and your productivity. 

Luckily, both Mattermost and Rocket.Chat help you avoid these problems, by offering you good search options. 

Mattermost allows you to search: 

• Messages, 
• Replies, and 
• All the files in your conversation history. 

Aside from that, various search modifiers are at your disposal, such as: 

• Exclusion symbol (-) — allows you to exclude from results all the posts containing a word of your choosing.
• Hashtags (#) — if you need to search for messages with a specific hashtag.
• Quotation marks (?) — if you need to search for a specific term.

You can also search messages: 

• From a specific user, 
• From a specified date, or
• Sent before and after the specified date. 

Rocket.Chat features ‘Intelligent Search.’ Unlike standard keyword filters, this uses semantic AI to understand user intent, finding relevant information across all rooms even if the specific keywords don’t match.

The winner in this category is Mattermost because it offers more nuanced search options.
