Slack vs Microsoft Teams
Slack and Microsoft Teams are the two dominant team messaging platforms. Slack is focused and integration-rich; Teams is bundled with Microsoft 365 and doubles as a video platform.
| Feature | Slack | Microsoft Teams |
|---|---|---|
| Channels/threads | ✓ | ✓ |
| Video conferencing | ✓ | ✓ |
| Screen sharing | ✓ | ✓ |
| App integrations | ✓ | ✓ |
| Office 365 integration | — | ✓ |

If your organization already pays for Microsoft 365, Teams is essentially free and deeply integrated with Word, Excel, SharePoint, and Outlook. That's hard to beat on value.
But Slack is a better communication tool. Its threading model, search, and integration ecosystem are superior. Teams tries to do everything — chat, video, files, apps — and the result can feel cluttered.
The real question is whether your team lives in Microsoft's ecosystem or not. If yes, Teams is the pragmatic choice. If no, Slack wins on experience.
