Fight for the Pinnacle: Slack or Microsoft Teams

Microsoft Teams and Slack have been giving each other a toe to toe competition in the Chat and Collaboration Application platform. The fight is to add better features, more integrations and providing a premium level product in the simplest way possible.

Fight for the Pinnacle: Slack or Microsoft Teams

As we wrap up the first decade of the 21st century, we see that more and more people from around the world are getting connected to each other with Instant Messaging apps. Each modern Instant Messaging software generally provides users either a separately installed software or a web-based client. Not only for personal messaging, but also for the corporate sector, for people around the globe, a cloud-based collaboration software is a must-have in today's business environment. Among the basket of Instant Messaging Softwares, two of these are sitting at the zenith of the enterprise: Microsoft Teams and Slack. 


Slack is a subscription type cloud-based instant messaging platform. It is developed by a single product organization Slack Technologies and initially released in August 2013.

Microsoft Teams 

Microsoft wished to bid for Slack in March 2016, but instead, they focused to improve Skype for Business. Later that year, in November 2016 Microsoft announced Teams to the world stating it as a direct competitor to Slack.

File Sharing and Collaboration 

Both Slack and Teams have a limit for uploading files. While Slack has a limit of 1gb, Teams is capped at 15gb. In Teams if any video file is uploaded, because of an advanced integrated software, the video will open immediately and play within Microsoft Teams without downloading. If the same video is uploaded in Slack, it needs to be downloaded by each of the participants to watch the video. 

The best collaboration feature of Microsoft Teams is that it allows you to not only play videos and comment at the same time, but also work using Office documents from OneDrive without leaving the app. This feature is missing in Slack. 


The fight for the Ultimate Chat Application will always be there. Each has its pros and cons. Slack being a bit friendlier for the Small Business Market users. On the other hand, Teams is better for bigger organizations. As a user, the choice between these two applications depend on what you require from a chat and collaboration application.
