  • Notifications,

  • Security.

Let’s start!

Skype vs Slack overview

Skype has been around since 2003, and it still serves as a communication tool for millions of users worldwide.

Skype’s homepage

With Skype, you can:

  • Host a video or audio conference, 
  • Record your calls, or 
  • Message your friends, family or colleagues.

Also, you can call those who aren’t on Skype. 

Namely, Skype can call landlines and mobile phones from anywhere in the world at low rates, as well as send SMS texts. 

Skype has long been used to stay in touch with long-distance friends and family. 

And, in recent years, Skype has rebranded to appeal to businesses for team communication as well. 

So, whatever needs you have, Skype promises to fulfill them.

Slack is a communication platform, mostly used by businesses to boost collaboration and communication.

Slack eliminates the need for emails and makes communication easier and quicker.

With Slack, you can exchange messages with your team members, but also with people outside your work. 

Slack lets you share files, connect by audio or video calls, and use other useful apps integrated with Slack.

Slack organizes your workspace in channels – designed to keep all messages, files, and people related to a particular topic in one place. 

Furthermore, Slack allows for integration with more than 2400 apps, so all of your necessities can be accessed from one workplace.

Here’s an overview of the main features of both apps:

Now, let’s take a detailed look.

Skype vs Slack pricing 1:0

When it comes to price, these two products are vastly different.

Skype is entirely free, whereas Slack does offer a free plan, but with limited features.

Skype offers their product at no cost.

You have access to all of the features that make Skype great.

This means that you can chat or connect via HD video calls with up to 100 people for up to 24 hours. 

Smart messaging offers mentions, emojis and reactions.

You also get access to other useful features such as:

  • Live meeting transcription,
  • Screen sharing, and
  • Meeting recording.

Slack, on the other hand, can get pricey.

Their Free plan offers:

  • Access to the most recent 90 days of message history,
  • 10 integrations with other apps like Google Drive or Office 365,
  • 1:1 audio and video conversations with screen sharing.

The Pro plan will set you back $7.25 per user per month, and it includes:

  • Full message history,
  • Unlimited integrations,
  • Audio and video conversations with screen sharing with up to 50 people,
  • Secure collaboration with outside organizations or guests from within Slack.

If this still doesn’t fulfill your needs, Slack offers the Business+ plan for $12.50, which comes with advanced security features and 24/7 support.

The Enterprise Grid plan is reserved for large-scale enterprises with up to 500,000 users, and the price is based on your company and needs.

Even though Slack offers great features in the paid plans, Skype still takes this round, since it is completely free of cost.

Skype vs Slack interface 0:1

Both Skype and Slack have a straightforward, user-friendly interface.
Skype has long been known for its simple and clean approach. 

But, if you want, you can customize it by changing themes or layouts.

Skype also features:

  • Grid view,
  • Spotlight view,
  • Together mode, and
  • Large gallery mode.

Slack’s interface is also user-friendly and simple.

However, the additional features make it more customizable, and the use of channels makes team communication easier. 

Channels are a great way to sort your conversations by topic and engage with people who are also interested in that topic. 

This makes for a cleaner workspace, which is easier to navigate. 

In Slack you can:

  • Customize the sidebar,
  • Customize welcome messages and emojis,
  • Choose theme colors, and
  • Chat in threads.

Skype vs Slack max participant capacity 1:0

When it comes to max participant capacity, it’s a no-brainer. 

For Skype, the maximum participant capacity on calls is always 100 people. As it doesn’t offer paid plans, that number can’t get higher.

On the other hand, Slack’s free plan allows for only 2 people on a call. 

With their paid plan, the number goes up to only 50 participants.

Skype offers a chance for more people to connect on a call, therefore this round goes to Skype.

Skype vs Slack notifications 1:1

I believe there are two types of people in the world — the ones who are always on Do Not Disturb mode and the ones who don’t want to miss a single notification.

Whether you belong to one or the other, both Skype and Slack have you covered.

Skype will notify you when:

  • A message comes through,
  • A contact comes online, 
  • Someone reacts to your message,
  • Someone makes a poll, and
  • A scheduled call is about to start.

Skype will also send notifications about system updates, tips or tricks. 

If you enable Smart notifications, Skype will only notify you when you’ve been quoted or mentioned in a message.

Furthermore, Skype can alert you to missed messages or calls through your email. 

Of course, all of these features can be enabled or disabled whenever you please. 

And if you need your peace and quiet, Do Not Disturb mode is readily available. You can also customize this mode, and turn on notifications for important calls. 

With Slack, notifications are also highly customizable. 

You get to choose what channels, messages, and threads you will be notified about. 

Some of the notification settings available include:

  • Notifications triggers,
  • Keyword notifications,
  • Notification schedule,
  • Sound and appearance,
  • Badge notifications,
  • Mobile notification timing,
  • Email notifications, and
  • Channel-specific notifications.

Do Not Disturb mode is available for when you want to immerse yourself in work, or conversely, punch out for the day. 

As far as notifications and their customization, Skype and Slack offer great notification systems and highly customizable alerts. So, this round is a tie.

Skype vs Slack search 0:1

Good search options are a surefire way to increase productivity

Instead of spending your time manually searching for that one specific message, you should be able to sort through your conversations and quickly find what you are looking for.

Skype offers standard search options.

In the search bar, you simply type the word or phrase you’re looking for. 

The results will start with the most recent message, and go on to show results from the previous six months.

Unfortunately, Skype doesn’t have options to filter your results or narrow down your search.

Searching for specific information is a more enjoyable experience in Slack.

Not only can you search through messages, but you can also search:

  • Files,
  • People, and
  • Channels.

Slack also allows you to search within the shared files.

Narrowing down your search is easy with Slack. You can:

  • Pick a time frame for your search,
  • Exclude certain channels, and
  • Pick file types.

Skype vs Slack communication 0:1

Let’s look at the communication features these two apps have in store for you.

When it comes to Skype, here are some of the features included:

  • Chat publicly or privately during meetings,
  • Share files and screens,
  • Record your video calls and save the sessions for up to 30 days, and
  • Create polls.

Additionally, you can have live captions and simultaneous translation during video calls, for up to 10 languages.

To add to that, Skype has the ability to call landlines and mobile phones, using Skype credit. You can also send text messages. 

For this service, you can pay as you go or purchase a subscription. 

In any case, prices are affordable, with one minute in a phone call costing around 1 cent.

Slack offers features that help you with asynchronous team communication

In Slack, you can:

  • Pin and save messages,
  • Edit, format and delete messages,
  • Set messages as reminders,
  • Schedule messages,
  • Turn questions into polls, and
  • Share files.

Slack’s use of threads and channels keeps your workspace clutter-free.

A downside to Slack is the fact that with the free plan, you only have access to messages from the last 90 days in your chat.

Huddles are Slack’s way of incorporating video calls into their app. 

You can start a huddle in any channel or chat, to begin a discussion with your teammates. 

Features available in a huddle include:

  • Screen sharing, 
  • Reactions, 
  • Emojis, and
  • Dedicated notes thread.

However, in the free plan, you can only create a 1-on-1 huddle. 

As for the paid plans, the maximum capacity goes up to 100.  

All things considered, Slack gets another point in this category, due to a plethora of useful options.

Skype vs Slack integrations 0:1

Third-party integrations help immensely when it comes to communicating with your team. 

Organizing your tools and apps into one streamlined workspace means improved productivity and less anxiety.

Unfortunately, Skype doesn’t offer any third-party integrations.

In contrast, Slack allows for integrations with over 2400 different apps.

Slack even categorizes these apps, for easier browsing.

Design, File Management, or Productivity are some of the categories in the extensive Slack App Directory. 

A few other ones include:

  • Essential apps – Slack for Gmail, Slack for Outlook, Zapier, and Asana.
  • Working from home apps — like Google Drive, Zoom, Trello, and Google Calendar.
  • Daily Tools apps — such as Slack for Gmail, Dropbox, Box, and Google Sheets for Workflow Builder.

The clear winner of this round is Slack. Among over 2400 integrations, you are sure to find everything you need for a seamless workflow.

When it comes to customer support, Skype offers some options:

  • Help center,
  • Virtual agent,
  • Skype community, and
  • FAQ page.

However, phone lines or web support lines are not available in Skype — so if you’re having a specific issue, you’re on your own.

In contrast, Slack offers a wider variety of support options, depending on the plan you have chosen.

In the free plan, you have the following features at your fingertips:

  • Email/Help Desk,
  • FAQs/Forum, and
  • Knowledge Base.

All of the paid plans offer 24/7 support, as well as 99.99% guaranteed uptime.

The Business+ plan, on top of all the formerly mentioned features, guarantees a four-hour response time.

The Enterprise plan means your needs are a priority, thanks to tailored support with a designated account and a customer success team.

The clear winner in this round is Slack, due to its advanced customer support.

Skype vs Slack security 1:0

In the final round, we will compare the security features of these two apps.

An important factor when choosing a platform for team communication is data security.

Unfortunately, neither Skype nor Slack offers top-notch safety features, so if safety is number one priority, you may be a bit disappointed. 

Skype uses AES (Advanced Encryption Standard), which is the gold standard of online communication safety.

Encryption protocols prevent anyone outside of the conversation from seeing your messages. Only the people in the conversation have the “key” to unlock the contents of the encrypted messages.

On the other hand, Slack doesn’t have advanced encryption. 

Slack encrypts data at rest and in transit, which is a less safe method of encryption. 

Both Skype and Slack use multi-factor authentication.

All in all, both Skype and Slack are generally safe, with Skype scoring this point thanks to their advanced encryption.

It was a fair fight, but in the end, Slack triumphed!

Even though Skype offers great features at no cost, Slack still wins this duel, thanks to an abundance of customization options, and the ease of communication. 

Integrations make for a more productive environment, and if you ever run into a problem with the app, Slack’s support system will take care of it.

Both Skype and Slack are among the best team chat apps — so, at the end of the day, it’s a matter of what you and your team need. 

But if you’re still on the fence, we have another recommendation.
