Mattermost ou Microsoft Teams (newer versions) : une bonne alternative sous Linux ?

Mattermost, alternative Linux à Microsoft Teams (newer versions)

Mis à jour le 29 octobre 2026

Notre avis

Mattermost is a strong replacement for Microsoft Teams if you control your own infrastructure and prioritize data sovereignty over corporate integration. It handles real-time chat, channels, and basic conferencing well, but it lacks the deep Office 365 ecosystem ties. It is ideal for developer teams or organizations willing to self-host. If your workflow relies heavily on Azure AD, Exchange calendars, or seamless Office file editing within the chat, Mattermost will feel limiting compared to Teams.

Designed primarily for developer workflows, not general business administration

Ouvrir vos fichiers Microsoft Teams (newer versions)

Mattermost does not natively open or edit Microsoft Office files (.docx, .xlsx, .pptx). You can upload these files to share them, but you must open them in a separate application like LibreOffice. There is no direct conversion or in-browser editing capability for these formats within the Mattermost interface.

Questions fréquentes

Can I use Mattermost for free?

Does Mattermost support screen sharing?

Yes, Mattermost includes built-in screen sharing for its native conferencing feature. You can share your entire screen or specific windows during a video call.
