Choose Mattermost if you prioritize data sovereignty, need full source code control, require on-premise deployment for compliance reasons, or want to minimize licensing costs while maintaining significant customization capabilities.","keyDifferences":[{"label":"Deployment Model","winner":"b","entityAValue":"Cloud-only (Microsoft-hosted)","entityBValue":"Self-hosted or cloud options"},{"label":"Source Code","winner":"b","entityAValue":"Closed proprietary","entityBValue":"Open-source (AGPL/Commercial)"},{"label":"Data Residency Control","winner":"b","entityAValue":"Limited to Microsoft data centers","entityBValue":"Full control with on-premise hosting"},{"label":"Microsoft 365 Integration","winner":"a","entityAValue":"Native integration with Office, SharePoint, Outlook","entityBValue":"Limited third-party integrations"},{"label":"Monthly Active Users","winner":"a","entityAValue":"320 million (as of 2024)","entityBValue":"500,000+ deployments globally"}],"winner":{"slug":"microsoft-teams","name":"Microsoft Teams"},"confidence":"high","entities":[{"name":"Microsoft Teams","slug":"microsoft-teams","url":"https://www.aversusb.net/entity/microsoft-teams","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/microsoft-teams"},{"name":"Mattermost","slug":"mattermost","url":"https://www.aversusb.net/entity/mattermost","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/mattermost"}],"faqs":[{"question":"Can I host Mattermost on my own servers?","answer":"Yes, Mattermost is designed for on-premise deployment. You can download the open-source version and run it on your own infrastructure, giving you complete control over data residency, security, and customization. Mattermost also offers managed cloud hosting if you prefer not to manage infrastructure yourself."},{"question":"Does Mattermost work with Microsoft Office documents like Teams does?","answer":"Mattermost can integrate with Office 365 via third-party integrations and webhooks, but it doesn't have the deep native integration that Teams provides. You can share Office files and link to SharePoint, but collaborative editing within Mattermost is limited. For heavy Office 365 users, Teams remains superior."},{"question":"How much does it cost to run Mattermost for 1,000 employees?","answer":"Mattermost's professional tier costs approximately $10-20 per user per month, totaling $10,000-20,000 annually for 1,000 users. However, the open-source community edition is free—you only pay for server hosting, infrastructure, and internal IT support. With Teams, expect $6,000-12,000 annually for the same user count."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/microsoft-teams-vs-mattermost))","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/microsoft-teams-vs-mattermost))), Microsoft Teams is a feature-rich enterprise collaboration platform with 320+ million users and deep Microsoft 365 integration, while Mattermost is an open-source, self-hosted alternative offering gre","dateModified":"2026-07-09T08:38:01.660Z"},"relatedQuestionsUrl":"https://www.aversusb.net/api/faq/microsoft-teams-vs-mattermost))","relatedComparisonsUrl":"https://www.aversusb.net/api/v1/related/microsoft-teams-vs-mattermost))","knowledgeGraphUrl":"https://www.aversusb.net/api/knowledge-graph/microsoft-teams-vs-mattermost))","claimReviewSchema":{"@context":"https://schema.org","@type":"ClaimReview","@id":"https://www.aversusb.net/compare/microsoft-teams-vs-mattermost))#claimreview","url":"https://www.aversusb.net/compare/microsoft-teams-vs-mattermost))","inLanguage":"en-US","isAccessibleForFree":true,"conditionsOfAccess":"Free","claimReviewed":"Microsoft Teams vs Mattermost","reviewBody":"Microsoft Teams is a feature-rich enterprise collaboration platform with 320+ million users and deep Microsoft 365 integration, while Mattermost is an open-source, self-hosted alternative offering greater control and lower licensing costs for organizations prioritizing data sovereignty and customization.","datePublished":"2026-07-09T08:38:01.587Z","dateModified":"2026-07-09T08:38:01.660Z","reviewRating":{"@type":"Rating","ratingValue":5,"worstRating":1,"bestRating":5,"alternateName":"High Confidence"},"author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B","url":"https://www.aversusb.net"},"itemReviewed":{"@type":"WebPage","@id":"https://www.aversusb.net/compare/microsoft-teams-vs-mattermost))","url":"https://www.aversusb.net/compare/microsoft-teams-vs-mattermost))","name":"Microsoft Teams vs Mattermost","inLanguage":"en-US"}}}
