Open Source Microsoft Teams Alternatives
Collaborate without Microsoft 365. Open source Teams alternatives for chat, video calls, file sharing, and team collaboration on your servers.
Microsoft Teams has become a central hub for many organizations, offering features like persistent chat, video conferencing, and seamless integration with the Microsoft 365 suite. However, its reliance on a centralized cloud service and potential data privacy implications often lead users to seek alternative solutions. Lock-in, the need for a Microsoft account, and the complexity of managing larger deployments can also be pain points.
