This article provides an in-depth, side-by-side comparison of Slack and Microsoft Teams as of 2026, looking at core features, integrations, user experience, security, pricing, and suitability for different team dynamics all to help you decide which platform is the best fit for your remote team.

The Evolution of Remote Collaboration: Slack and Microsoft Teams

Remote teams rely heavily on seamless communication that mimics in-person interaction and integrates multiple digital workflows. Slack, launched in 2013, quickly became synonymous with agile messaging and developer-friendly integration. Microsoft Teams, initially released in 2017 as part of Microsoft 365, has grown steadily, leveraging Microsoft’s enterprise foothold and deep integration with productivity apps like Word, Excel, and OneDrive.

In 2026, both platforms have evolved far beyond simple messaging apps, incorporating AI-assisted features, video conferencing, task management, and universal search capabilities.

User Interface and Experience

Slack

Slack’s clean, minimalist UI focuses on conversation threads organized by channels. The sidebar for channels and direct messages is customizable, and Slack's visual design emphasizes clarity and ease of navigation.

• Conversations are threaded, meaning related responses stay grouped for easier follow-up, reducing clutter.
• A powerful universal search indexes messages, files, and integrations, making information retrieval swift.
• Slack lets users customize their experience extensively with themes, custom emojis, and notification preferences per channel or group.
• Slack hones in on text communication but supports video calls (up to 15 participants natively).
• Mobile and desktop apps maintain high performance with offline support and push notifications.

Microsoft Teams

Microsoft Teams’ interface is more comprehensive, integrating chat, video, meetings, file storage, and app tabs within a single unified workspace.

• Chats and channels support threaded conversations but are visually denser than Slack’s minimalist threads.
• Native deep integration with Microsoft 365 apps means you can co-edit documents, present in meetings, and share files seamlessly within Teams.
• Teams supports large-scale video conferencing natively for hundreds of users with advanced meeting controls, breakout rooms, and recording options.
• Multi-window chat and meeting views on desktop improve multitasking and visibility into ongoing discussions.
• Teams also serves as a hub for third-party app integrations from its app store with increasing availability.

Collaboration Features

Slack

• Emphasizes asynchronous communication making it easy for teams across time zones to stay connected.
• Supports powerful channel organization with public, private, and shared channels (across organizations).
• Offers rich app integrations (over 3,000 apps and bots) ranging from project management (Trello, Jira) to CI/CD tools and analytics.
• Includes Workflow Builder, a no-code automation tool to customize processes without programming.
• Slack Connect enables secure cross-company collaboration via shared channels replacing email for many scenarios.

Microsoft Teams

• Deep collaboration within Microsoft 365 apps is a competitive advantage, enabling real-time document editing, calendar scheduling, and workflow automation in Power Automate.
• Team Channels support threaded messages like Slack, but also include tabs for planners, notes, SharePoint sites, and dashboards to centralize project tools.
• Advanced video meeting features, including transcription, AI transcription summarization, and noise suppression.
• Teams support rich task management through Microsoft Planner and To-Do integration.
• Offers comprehensive compliance, governance, and security controls critical for enterprises.

Security and Compliance

Slack and Teams both maintain enterprise-grade security but differ in approaches and ecosystem coverage.

• Slack uses encryption in transit and at rest, SOC 2 Type II compliance, and supports SSO, TLS, and Enterprise Key Management (in Enterprise Grid).
• Microsoft Teams complies with ISO 27001, HIPAA, FedRAMP, GDPR, and offers advanced security through Microsoft Defender and Azure AD integration.
• Teams excel in regulatory compliance favored by healthcare, finance, and government sectors.
• Administrative controls in both platforms allow data loss prevention (DLP), information barriers, and audit logs suited for industry needs.

Pricing Comparison

Slack

• Free tier with limited searchable messages (up to 90 days), 10 app integrations, 1:1 video calls.
• Pro plan starts at $8/user/month with unlimited message archive, group video calls, and screen sharing.
• Business+ tier at $15/user/month adds compliance and security features.
• Enterprise Grid required for large organizations with complex needs, pricing customized.

Microsoft Teams

• The free version supports up to 100 participants, unlimited chat, and file storage limited to 5GB per user.
• Microsoft 365 Business Basic plan at $6/user/month adds Office Online apps, 1TB OneDrive storage, and standard meeting capabilities.
• Business Standard at $12.50/user/month includes full Office apps, webinar capabilities, and advanced security.
• Enterprise plans (E3, E5) with advanced compliance and analytics start at $30/user/month and up.

Why It Matters

Choosing between Slack and Microsoft Teams goes beyond comparing features—it's about which ecosystem your team already uses, your security needs, team size, and collaboration style.

• Slack is better suited for teams valuing fast, flexible text-first communication with deep support for third-party tools and startups or smaller teams seeking agility.
• Microsoft Teams fits organizations deeply invested in the Microsoft 365 environment needing a comprehensive collaboration tool encompassing email, meetings, file management, and compliance at scale.
