Slack vs Microsoft Teams: Which Should Your Team Use in 2026?
The two giants of workplace chat, compared on price, integrations, and day-to-day experience.
Slack and Microsoft Teams dominate workplace chat, but they win for different reasons: Slack on experience and integrations, Teams on bundling and price. Here’s how to choose.
Pricing
Teams is hard to beat on price — it’s included with Microsoft 365, and standalone plans start around $4 per user. Slack’s paid plans start at roughly $7.25 per user, and its free tier hides messages older than 90 days.

Integrations and developer experience
Slack’s app directory and API remain the gold standard — thousands of integrations and a bot ecosystem that engineering teams love. Teams integrates deepest with Office: live-editing a shared Excel file in a chat tab is where it shines.

The verdict
If your company already pays for Microsoft 365 and lives in Office documents, Teams is the pragmatic pick. If chat is the center of your workflow and you depend on best-in-class integrations, Slack still earns its premium.
