Microsoft Teams vs Slack

Choose Microsoft Teams if…

• Organizations already using Microsoft 365
• Included in many Microsoft 365 plans
• Strong meetings and calling

Choose Slack if…

• Companies that want the largest integration ecosystem for chat
• You need Linux, which Microsoft Teams doesn't list
• Huge integration ecosystem
• Polished threads and huddles

What is Microsoft Teams?

Microsoft Teams combines persistent chat, video meetings, calling and file collaboration, and it is bundled into many Microsoft 365 business plans. Teams and channels organize conversations, while SharePoint and OneDrive store shared files that can be co-edited in Word, Excel and PowerPoint without leaving the app. Meetings support large audiences, recordings, transcription and webinars. Organizations already standardized on Microsoft often get it at no extra cost, which drives adoption. A free version exists for personal use and small groups, with business features in paid plans.

What is Slack?

Slack organizes team communication into channels by topic, project or team, alongside direct messages, threads and audio huddles. Thousands of integrations bring alerts and actions from other tools into conversations, and Workflow Builder automates routine requests. Slack Connect lets companies share channels with partners and customers. It is owned by Salesforce. The free plan limits how much message history you can see, which is a frequent reason small teams and communities look for alternatives, while paid plans unlock full history, more integrations and administration controls.
