# Microsoft Teams vs Slack Published January 1, 2026 · Updated August 10, 2026 Slack is the top pick for most Mac users looking at communication. It has a free tier and installs in one Homebrew command. Microsoft Teams is the stronger choice if you are moving off Slack Pro. As of October 2026, both install with brew install --cask microsoft-teams and brew install --cask slack. For most Mac users in 2026, Slack is the better choice for communication because it ranks higher in Homebrew install popularity (#40). Both install with a single Homebrew command, so the switching cost is low. Choose Microsoft Teams instead if you are moving off Slack Pro. ## Head to head | Factor | Microsoft Teams | Slack | | --- | --- | --- | | Price | Free | Free | | Open Source | No | No | | Replaces | Slack Pro ($8.75/month) | Microsoft Teams ($6/month) | | Best for | chat, video, meetings | chat, team, business | | Install | brew install --cask microsoft-teams | brew install --cask slack | | Category | Communication | Communication | ## Microsoft Teams Meet, chat, call, and collaborate in just one place Install: `brew install --cask microsoft-teams` [Microsoft Teams on Bundl](https://bundl.run/apps/microsoft-teams) ## Slack Business communication platform Install: `brew install --cask slack` [Slack on Bundl](https://bundl.run/apps/slack) ## Features - **Interface & Mac Native Feel.** Slack wins decisively. It respects Mac conventions and offers a fluid, delightful experience that Teams' utilitarian interface cannot match. - **Messaging & Threading.** Slack's threading and notification management are superior for high-volume asynchronous communication, keeping noise levels manageable. - **Video Conferencing.** Teams wins for formal meetings and video quality. Slack Huddles are excellent for casual chats, but Teams replaces the need for Zoom entirely. - **AI & Automation.** Teams wins on raw power and cross-app context. Copilot is a more broader productivity assistant, provided you pay for it. - **File Management & Collaboration.** Teams wins for document-heavy workflows. The SharePoint backend provides structure that Slack's flat file stream lacks. - **Integrations & Ecosystem.** Slack wins for third-party breadth and developer experience. It plays nicer with the 'rest of the internet' than Teams. - **Search Functionality.** Slack's search is faster, more granular, and easier to navigate, acting as a reliable institutional memory bank. ## FAQ ### Can I use Microsoft Teams for free on a Mac? Yes, there is a 'Microsoft Teams (free)' version available for Mac. It allows for unlimited 1:1 meetings for up to 30 hours, group meetings for up to 60 minutes (100 participants), and 5GB of cloud storage. However, it lacks the advanced administration, recording, and transcript features of the paid business plans. It is sufficient for freelancers or small hobby groups, but businesses will quickly hit the limits. ### Does Slack have video conferencing like Teams? Slack has 'Huddles,' which support audio, video, and screen sharing for up to 50 people. While excellent for quick, informal syncs, they lack the solid features of Teams meetings (like breakout rooms, webinar registration, and advanced recording controls). Most Slack-heavy companies still pay for Zoom or Google Meet for their formal external meetings. ### Is Microsoft Teams slower than Slack on Mac? Historically, yes. Teams was notorious for being resource-heavy. In 2026, the 'New Teams' app (rewritten with WebView2/React) is significantly faster and uses less memory than before. However, Slack is still generally perceived as 'snappier' and lighter, especially on Apple Silicon Macs, due to its cleaner codebase and aggressive optimization for the platform. ### Can I edit Word documents inside Slack? Not natively. If you share a Word doc in Slack, it previews it, but to edit, you must open it in the Word app or browser. In contrast, Microsoft Teams allows you to open, edit, and co-author Word, Excel, and PowerPoint files directly within the Teams interface without ever leaving the application, which is a major workflow advantage for Office users. ### Which AI is better: Slack AI or Microsoft Copilot? They serve different purposes. Microsoft Copilot is a 'Creator', it can write emails, draft documents, and create PowerPoint slides based on your data. Slack AI is a 'Summarizer' and 'Navigator', it excels at recapping long chat threads, finding hidden context in channels, and automating workflows. Copilot is more capable but more expensive; Slack AI is more focused on communication efficiency. ### Do I need Salesforce to use Slack effectively? No, but it helps. Slack works perfectly fine without Salesforce. However, since Salesforce owns Slack, the integration between the two is deeper than any other CRM. Features like 'Sales Improve' and 'Agentforce' make Slack a superpower for sales teams using Salesforce, but for engineering or creative teams, the standalone Slack experience is still top-tier. ### Can I use both Teams and Slack together? Technically yes, but it is not recommended. Running both creates 'shadow IT' and information silos, half the conversation happens in Slack, half in Teams, and search becomes a nightmare. It's best to pick one as the 'System of Record' for internal comms. Some companies use Teams strictly for video calls and Slack for chat, but this is an expensive compromise. ### How secure is Slack compared to Teams? Both are enterprise-grade. Teams has a slight edge for highly regulated industries (Gov/Defense) because of its deep integration with Microsoft Purview, Intune, and data residency controls. Slack's 'Enterprise Grid' plan offers similar features (EKM, HIPAA support, data residency), but these are only available at the highest price tier, whereas Teams includes many security features in standard business plans. ### Does Teams work well with Google Workspace? It's possible but clunky. You can use Teams for chat/video while using Google Drive for files, but you lose the 'magic' of Teams (co-authoring, file management). Slack is a much better companion for Google Workspace shops, as it treats Google Drive files as first-class citizens, with rich previews and permission management directly in the chat. ### What is the best alternative to both for Mac users? If neither suits you, 'Discord' is popular for casual/crypto communities but lacks enterprise controls. 'Zoom Workplace' is adding chat features to compete. 'Rocket.Chat' or 'Mattermost' are open-source, self-hosted alternatives for privacy-focused technical teams. However, for a general business context in 2026, Teams and Slack remain the duopoly. ## Sources - [Slack pricing](https://slack.com/pricing) - [Slack Pro plan](https://slack.com/pricing/pro) - [Microsoft Teams business plans](https://www.microsoft.com/en-us/microsoft-teams/compare-microsoft-teams-business-options) - [Download Microsoft Teams](https://www.microsoft.com/en-us/microsoft-teams/download-app) - [Compare Microsoft 365 business plans](https://www.microsoft.com/en-us/microsoft-365/business/compare-all-microsoft-365-business-products) - [Slack plans and features](https://slack.com/help/articles/115003205446-Slack-plans-and-features) - [Slack vs Microsoft Teams in 2026 (SMB pricing overview)](https://www.ciotech.us/slack-vs-microsoft-teams-2026-smbs/) ## Related - [Zoom vs Microsoft Teams](https://bundl.run/compare/zoom-vs-teams) - [Google Meet vs Microsoft Teams](https://bundl.run/compare/google-meet-vs-microsoft-teams) - [Discord vs Microsoft Teams](https://bundl.run/compare/discord-vs-microsoft-teams) - [Slack vs Discord](https://bundl.run/compare/slack-vs-discord) - [Element vs Slack](https://bundl.run/compare/element-vs-slack) ```json { "@context": "https://schema.org", "@graph": [ { "@type": "Organization", "@id": "https://bundl.run/#organization", "name": "Bundl.run", "url": "https://bundl.run", "logo": { "@type": "ImageObject", "url": "https://bundl.run/og-image.png", "width": 1200, "height": 630 }, "description": "The Ninite for Mac.
