Frequently Asked Questions
Should I use Slack or Microsoft Teams?▾
Use Microsoft Teams if your organization is already on Microsoft 365 — it's included at no extra cost and the SharePoint/OneDrive integration is valuable. Use Slack if you're not in the Microsoft ecosystem and prioritize integrations, usability, and developer workflows.
Is Microsoft Teams free?▾
Microsoft Teams Essentials is $4/user/month. Teams is also included in all Microsoft 365 Business plans starting at $6/user/month. There's a limited free version of Teams, but it lacks key features like meeting recordings.
Is Slack better than Teams for remote teams?▾
Slack is generally preferred by remote-first tech companies for its UX, integration depth, and async communication features. Teams is preferred by remote enterprise teams already in the Microsoft ecosystem, especially those using SharePoint.
Can Slack and Teams work together?▾
Yes. Microsoft offers a Slack-Teams integration that allows users on both platforms to message each other. This is useful for companies that collaborate with clients or partners using different platforms.
