Mattermost vs Skype: What are the differences?

Developers describe Mattermost as "Open-source, self-hosted, Slack alternative". Mattermost is modern communication from behind your firewall. On the other hand, Skype is detailed as "Voice calls, instant messaging, file transfer, and video conferencing". Skype’s text, voice and video make it simple to share experiences with the people that matter to you, wherever they are.

Mattermost can be classified as a tool in the "Group Chat & Notifications" category, while Skype is grouped under "Web and Video Conferencing".

Some of the features offered by Mattermost are:

  • All your team communication in one place, searchable and accessible anywhere
  • Slack-compatible, not Slack-limited. Imports Slack channels, users and themes. Offers Slack-compatible webhooks and integrations including Hubot, Jenkins, GitLab and others
  • Self-host ready with System Console and IT admin tools for managing dozens of team sites. Installs with Linux binary, plus Docker, Heroku, AWS, Azure and Cloud Foundry options

On the other hand, Skype provides the following key features:

  • Calling- Make free Skype to Skype calls or call mobiles and landlines home and abroad at low rates.
  • Video- Catch up face to face or get a whole group together on a video call.
  • Messaging- You're always in the loop with instant messaging, voice messaging and sending texts.

"Open source" is the top reason why over 54 developers like Mattermost, while over 248 developers mention "Free, widespread" as the leading cause for choosing Skype.

Mattermost is an open source tool with 15.4K GitHub stars and 3.14K GitHub forks. Here's a link to Mattermost's open source repository on GitHub.

According to the StackShare community, Skype has a broader approval, being mentioned in 737 company stacks & 733 developers stacks; compared to Mattermost, which is listed in 38 company stacks and 24 developer stacks.

Advice on Mattermost and Skype

Hi, I am helping teachers in my kid's schools to set up distance learning and wanted to see what is better between Webex, Zoom, and Skype (although only putting this one in as most parents probably have it). The children are 8-9, so they won't be using it on their own and the parents have no experience using Webex or Zoom.

The main use will be for the teacher to explain what they will be covering in the week and enable some social interaction between the kids.

I need to be easy to use for about 20-25 people.

Thanks for your advice, Lisa

I consider Skype dead. Even Microsoft strongly neglected it. Webex is more corporate-oriented. So for your use case, I recommend Zoom. It is easy to set up, and the quality is very good. Zoom became such a household name that the average person heard about it. Moreover, any person probably has friends who may have used it. So it will be easier for people to get some community help.

Hi, Lisa,

I haven't used Skype in a long time. I have I lot of experience with Zoom and Webex. Both for me are very good tools, especially if you have money to pay for (to unlock more features, like more people in a video conference - Zoom).

Nowadays, I've used more Webex with my undergraduate students, I'm using the free account. Cloud recording is a features very useful, especially while using the free account (thanks Cisco!). Webex has control features very useful (e.g., mute, raise hand etc).

Kind regards,

We've been using Zoom for about a half a year and it's stability is unbeatable. We have all-hands on Fridays with 100+ participants. The free tier can easily handle the requirements, the only limitation is that max meeting length is 40 minutes. After that you can immediately restart the meeting, but the pro option is also very affordable. It also features screen sharing and whiteboard sharing out of the box. I also appreciate that it's not mandatory to register an account to attend a meeting.

From my experiences I feel like Zoom is a pretty intuitive program to teach kids, however Skype might be more common amongst them already.

I am a big fan of Microsoft Teams.

They all do the same pretty much but Teams I find the bells and whistles are easier to find, like custom backgrounds... creating groups for topic discussions that remain there until you want to change/edit or delete. Easy to share files.
