Microsoft Teams Alternatives
Frustrated with Teams? Compare alternatives with better performance, no lock-in, and simpler admin.
Why Teams Leave Teams
Performance Issues
Teams is notorious for high memory usage and slow performance. The Electron-based app can consume gigabytes of RAM.
Microsoft Ecosystem Lock-in
Teams pushes you deeper into Microsoft's ecosystem. Every integration point creates more dependency on Microsoft services.
Complex Administration
Managing Teams requires navigating multiple admin centers. Simple changes can require Azure AD, Teams Admin, and SharePoint portals.
Hidden Costs
While 'included' with M365, premium features require additional licenses. Governance, compliance, and advanced features add up.
