Microsoft Teams vs Slack: 2021 Review (Features, Pricing)

When Microsoft decided not to acquire Slack in 2016 and instead come up with their own collaboration app called Microsoft Teams, it meant war. 🥊

And it’s a close one!

Sure, if you compare Slack vs Microsoft Teams, it’s hard to spot a difference at first glance. 

However, each one can offer you something a little different when you look closer. 👀

Confused about which side to take in this Microsoft Teams vs Slack war? 

In this article, we’ll do a detailed Microsoft Teams vs Slack comparison to help you pick one. 

(We’ll also reveal the best alternative for these two apps.) 🤫

Ready for the showdown? Let’s begin.

Note: we’ll first give you a brief overview of each tool and its most attractive features. But feel free to jump straight to the Microsoft Teams vs Slack comparison. 

What Is Microsoft Teams? 

Microsoft Teams is a popular collaboration and communication tool that is a part of the Microsoft Office 365 suite. 

Apart from instant messaging, you can use this tool to make audio and video calls, share documents, take meeting notes, etc.

Here are some of its best features. ✨

1. Teams

For effortless collaboration, MS Teams lets you create ‘teams for different projects or groups. Moreover, if you work in a large company, you can create teams within teams to keep the conversations more organized. 

You can even bold, italicize, or underline your messages in these teams, just like you do in Word. 

And while you interact and work in your team’s space, you can tag people to capture their attention.

2. Connected apps

Another key feature that makes Teams a great tool is its MS Office 365 integration

When you create a team, a dedicated Office 365 group will be formed for you. This functionality lets you access files across all the Office 365 suite apps from a single platform.

This way, Teams users can work together on Word documents, Excel spreadsheets, Powerpoint presentations, etc., in real-time.  

3. Audio and video conferencing

MS Teams allows you to have one-on-one calls with anyone in your organization. 

And if you need to address a larger team, no worries.

You can host meetings with up to 100 attendees in the free version and host live events with up to 10,000 attendees, including employees and guests, when you upgrade to the paid plan!

Can it get any better? Yep. 

You can make calls more productive with meeting recordings, blur your background for better focus, schedule meetings, etc.  

4. Screen sharing

A Microsoft Teams user can collaborate from anywhere and on any device with the screen sharing option. You can even control what you want others to see or not see.👀 

Whether you want to give a product demo or conduct a town hall, you can keep everyone on the same page with screen-sharing functionality. 💻↔️💻

Not sure if Teams can contribute to your team spirit? 

Maybe explore the best 5 Microsoft Teams alternatives available today. 

Now, let’s take a deeper look at one of those alternatives, Slack. 

What Is Slack? 

The Slack app is one of the fastest-growing channel-based collaboration software today. 

It offers instant messaging, easy file sharing, and thoughtful accessibility features.

This platform even has a clever bot to send automated responses on your behalf while you’re busy photographing your cat for being the cutest one ever. 😼

Let’s look at the top features of the Slack messaging app: 

1. Organized channels

While the Microsoft Teams app lets you create channels within teams, Slack organizes all conversations under channels. According to Slack, “there’s nothing like too many channels.”

With the Slack app, you can easily create public and private channels based on topics, projects, office locations, etc.

You can use channels to send instant messages to teammates when the eureka moment hits.💡 Add funny work memes, quirky emojis, and gifs to make conversations fun.

Tired of flooded inboxes?

With Slack, each channel gets its unique email address in the paid version. 

You can push emails directly to a channel instead of forwarding them to every team member with this functionality. Good riddance, cc and bcc. 

2. Collaboration with external teams

Slack’s connect feature offers unlimited external collaboration in its paid version. This way, you can keep clients in the loop about project updates.  

Goodbye, confusing and misplaced email threads. 👋

You can move confidential conversations with any external user like vendors, clients, and agencies to Slack channels, making collaboration a piece of cake. 

3. Automations

Want to increase your productivity and save time on routine work? 

Use Slack’s workflow builder to automate everyday tasks like sharing updates or creating standard request processes. You can also integrate with apps like Zapier to automate workflows. 

4. Audio and video calling

Not everyone is a chat person. 

For this reason, the Slack platform offers one-to-one audio and video calls to help you simplify and communicate ideas better. If you wish to add more people to your video conferencing, go for the paid plan to add 15 participants in a call. 

But guess what? 

The MS Teams platform lets you add 100 people even in its free version. 

If you’re a Slack user, we bet you’re feeling like this:

Slack does make amends by offering third-party integrations with other audio and video conferencing tools. You can even join calls without leaving important channel conversations. 

Not sure if Slack can save you from slacking? 

Check out the top 5 Slack alternatives you can use instead.

Now that we’ve explored what Teams and Slack can do, let’s compare them on their best features.

Microsoft Teams vs Slack

There’s no denying that Slack and Teams have identical features.

However, they do have some key differences too. 

Ready to find out? 

Let’s turn up the heat for this Slack vs Microsoft Teams battle. 🔥🔥🔥

1. User interface

A cluttered user interface is like a highly detailed clothing label

All you want to know is the size of the sweater, but instead, you could end up learning about the sheep that sourced the wool before you find the information you were looking for. 🙈

In short, keep it simple. 

Here’s what most users feel about these apps’ interfaces: 

A. Microsoft Teams

Microsoft Teams’ user interface feels pretty similar to that of Slack. 

*Psst* It looks like someone took some Slack inspiration.

If you’re a new user, you can get some onboarding help with its docs and tutorials.

The option to create embedded teams keeps conversations more organized. 

A big plus for companies with large teams. ➕➕➕

But if you like things to be more colorful, MS Teams has only three theme options: dark gray, black, and white.

If you want to mix and match or tweak certain colors, you’re out of luck! 

B. Slack

On the other hand, Slack’s user interface is quite sleek and has become the industry standard. You have several color theme options to customize the app’s look to suit your preferences. 

As a new Slack user, you won’t need to watch boring tutorials to learn how to use the features because the app is quite intuitive and user-friendly. 

Slack isn’t slacking here. 😉

Additionally, it’s pretty easy to send a message to another user or team. Just tag teammates or channels and use the shortcuts to get things done on the fly. 

2. Channels and meetings

Back from your holiday? 

Now imagine the pain of searching through endless email threads just to find relevant work stuff. 😅

Luckily, with ‘teams’ in MS Teams or ‘channels’ in Slack, finding all work-related conversations is easy because they’re all on one platform.

But just how good are Teams and Slack at doing this? 🤔

A. Microsoft Teams 

In Teams, a user can create sub-teams for better data management. You can even have a private channel within a team and control access to confidential X files

When it comes to meetings, you can make 60-minute audio or video calls with the free plan. 

You can also record meetings and use screen sharing for a better call experience. 

B. Slack

On the other hand, Slack doesn’t let you create channels within channels. 😒

Admins, good luck managing a zillion collaboration channels. 

For meetings, Slack allows only one-on-one audio and video calling in its free plan.

Microsoft wins this round. 

3. Integrations

Collaboration software is truly worthy if it supports other productivity apps. It helps you do it all from a single platform. 

Which of these two apps can be a jack of all t̶r̶a̶d̶e̶s̶ apps?

A. Microsoft Teams

As of July 2021, Teams offers an app integration with 700+ popular apps. 

Some of these tools include: 

And if you’re an Office 365 user, Teams seems like the obvious choice. 

B. Slack

Slack integration keeps getting strong, with over 2400 apps available in its ecosystem. 

These include:

It even offers integration with every Microsoft product. 

A total integration powerhouse! 😎

4. Pricing

Whenever you’re comparing tools, you can’t leave out their prices, right?

Let’s take a look at which one is more friendly on your wallet:

A. Microsoft Teams

Teams has no exclusive plans. 

You can try it for free or buy it as part of the Microsoft 365 suite. 

Here’s what each plan offers: 

  • Free plan: unlimited message search, guest access, and 100 meeting participants
  • Microsoft 365 Business Basic plan ($5 per user per month): 300 participants, meeting recordings, and 1TB file storage 
  • Microsoft 365 Business Standard plan ($12.50 per user per month): 300 participants, 1TB personal file storage, and access to any Microsoft Office desktop app 

B. Slack

Slack has a free version and offers two paid plans. 

Here’s what each plan offers: 

  • Free plan: search from 10,000 recent messages, 5GB file storage, audio, and video calls 
  • Pro plan ($6.67 per month): unlimited integrations, group audio and video conferencing with 15 members, 10GB file storage per user 
  • Business+ plan ($12.50 per month): unlimited message history, 20GB storage/team member, and 24/7 support

Who conquers the Slack vs Microsoft Teams war?

Honestly, there’s no clear-cut winner here. 🤷‍♀️

The Teams app is a better option if you already have an Office 365 subscription.

But it doesn’t offer anything exciting in terms of the user interface, and its app integration options are far less than Slack. 

On the other hand, Slack is one step ahead with an intuitive chat app and 2,000+ integrations.

However, Slack doesn’t let you create sub-channels for better task management.

Not to mention both these apps also lack task management functionalities like goal setting, creating and assigning tasks, and tracking work progress. 

If you want such features, you’ll probably have to go for a third-party app integration.
