Best Free and Open Source Alternatives to Microsoft

Best Free and Open Source Alternatives to Microsoft Teams

Microsoft’s stance for decades was that community creation and sharing of communal code (later to be known as free and open source software) represented a direct attack on their business. Their battle with Linux stretches back many years. Back in 2001, former Microsoft CEO Steve Ballmer famously tarnished Linux “a cancer that attaches itself in an intellectual property sense to everything it touches”. Microsoft also initiated its “Get the Facts” marketing campaign from mid-2003, which specifically criticized Linux server usage, total cost of ownership, security, indemnification and reliability. The campaign was widely criticized for spreading misinformation.

However, in recent years, there has been a partial shift by Microsoft to embrace the open source software paradigm. For example, some of their code is open sourced. Examples include Visual Studio Code, .NET Framework, Atom, and PowerShell. They have also made investments in Linux development, server technology and organizations including the Linux Foundation and Open Source Initiative. They have made acquisitions such as Xamarin to help mobile app development, and GitHub a hugely popular code repository for open source developers. And they have partnered with Canonical, the developers of the popular Ubuntu distro. But many developers remain hugely sceptical about Microsoft and their apparent shift to embrace open source.

This series looks at the best free and open source alternatives to products and services offered by Microsoft.

Microsoft TeamsMicrosoft Teams is a proprietary business communication platform. The service integrates with the company’s Office 365 subscription office productivity suite.

Teams is replacing other Microsoft-operated business messaging and collaboration platforms, including Skype for Business and Microsoft Classroom.

What are the best free and open source alternatives to Teams?


1. Mattermost

Mattermost is an open-source, self-hostable online chat service with file sharing, search, and integrations. It is designed as an internal chat for organisations and companies, and mostly markets itself as an open-source alternative.

Mattermost distinguishes itself from proprietary messaging software thanks to several features, namely:

  • Slack-compatibility: users can import other users, public channel history, and theme-setting colours;
  • Good mobile experience with comment threads and file sharing features;
  • Mobile and desktop apps, in addition to web apps; and
  • User-friendliness: Mattermost is easy to deploy, manage, and upgrade.
