Slack vs Microsoft Teams 2026: Which Is Better for Remote Teams?

Slack is the standard for tech companies. Its GitHub, Jira, PagerDuty, and CI/CD tool integrations are best-in-class. Slack's slash commands, webhooks, and developer APIs let engineering teams build custom automations. The cleaner UX drives faster adoption. Most developer job postings list Slack experience — Teams is rare in pure-tech environments.

Microsoft Teams dominates enterprise adoption. It's bundled with Microsoft 365, which most large corporations already license. Teams handles compliance requirements (HIPAA, FedRAMP, ISO 27001) and integrates with SharePoint for document management and OneDrive for file storage. IT departments love the Azure Active Directory integration for single sign-on and user management at scale.

For formal video meetings, webinars, and large all-hands, Microsoft Teams is the stronger platform. 1,000-participant calls, breakout rooms, Together Mode, live captions, meeting recording with auto-transcription, and deep Outlook calendar integration make it the enterprise video standard. Slack Huddles is excellent for quick 3-person standups but isn't designed for company-wide events.

Slack's 2,600+ app integrations are unmatched. Salesforce, Zendesk, Notion, Figma, Stripe alerts, GitHub deployments, AWS alerts — every major SaaS tool has a first-class Slack integration. Teams has Power Automate for workflow automation (excellent within the Microsoft stack) but fewer pre-built third-party connectors. If your company runs on best-of-breed SaaS tools (not Microsoft products), Slack's integration breadth is decisive.

Is Slack better than Microsoft Teams?

Slack is better for most startups, tech companies, and teams that prioritize a clean UX, rich third-party integrations, and developer-friendly workflows. Microsoft Teams is better for enterprises already on Microsoft 365 — it integrates deeply with Outlook, SharePoint, and OneDrive, and often comes included in existing Microsoft licenses at no extra cost. The right choice depends on your existing tech stack more than on feature count.

Which is cheaper — Slack or Microsoft Teams?

Microsoft Teams wins on price for most companies. Teams is included in Microsoft 365 Business Basic ($6/user/mo), which most enterprises already pay for. Standalone Teams Essentials costs $4/user/mo. Slack's paid plans start at $7.25/user/mo (Pro) — and the free tier limits message history to 90 days, which is frustrating. If you're already paying for Microsoft 365, Teams is essentially free.

Is Slack better than Teams for small businesses?

For small teams (under 50 people), Slack's free tier is a good starting point — but the 90-day message limit becomes painful fast. Slack Pro at $7.25/user/mo gives unlimited history and is worth it for most teams. Microsoft Teams Free is also available with no message limits. Small businesses not on Microsoft 365 will find Slack's UX more pleasant; those already on Microsoft 365 should default to Teams for cost reasons.

Does Slack or Teams have better integrations?

Slack wins on third-party integrations — it has 2,600+ app integrations via the Slack App Directory, covering every major SaaS tool (Salesforce, Jira, GitHub, Notion, Google Workspace, etc.). Teams has strong Microsoft integrations (Outlook, SharePoint, Power Automate) but fewer third-party options. For companies in the Microsoft ecosystem, Teams integrations are excellent; for companies using a mix of best-in-class SaaS tools, Slack's breadth is unmatched.

Can Slack and Microsoft Teams work together?

Yes — Microsoft introduced Slack and Teams interoperability in 2022, allowing cross-platform messaging between Slack and Teams users. This is useful for agencies, clients, or partner organizations using different tools. You can also connect both tools to shared project management systems (Jira, Asana, Notion) so both audiences see updates. Many companies end up running both tools for different workflows.

Which is better for video calls — Slack or Teams?

Microsoft Teams wins for video calls. Teams supports up to 1,000 participants in a single call, has background blur/replacement, Together Mode, breakout rooms, meeting recording with auto-transcription, and deep calendar integration with Outlook. Slack Huddles (their video feature) is lightweight and great for quick informal calls, but lacks the enterprise meeting features Teams has. For large all-hands meetings or webinars, Teams is the clear winner.
