Slack vs Microsoft Teams

Slack vs Microsoft Teams for Product Teams (2026)

Slack and Microsoft Teams are the two dominant team communication platforms. For product teams, the choice often comes down to ecosystem: Slack integrates with modern developer and PM tools, Teams integrates with Microsoft 365.

This guide compares them from a product management perspective.

Slack

Slack is a channel-based messaging platform with a massive integration ecosystem. It connects to Linear, GitHub, Figma, Amplitude, and most modern product tools. Slack Connect allows cross-organization communication.

Microsoft Teams

Microsoft Teams is the communication hub for Microsoft 365. It combines chat, video calls, file sharing, and Office integration. Strong for organizations already on Microsoft 365.
