Mattermost vs. Microsoft Teams (2026 standalone client): eine gute Linux-Alternative?

Mattermost als Linux-Alternative zu Microsoft Teams (2026 standalone client)

Aktualisiert am 29. Oktober 2026

Unser Fazit

Mattermost is a solid replacement for Microsoft Teams (2026 standalone client) if you prioritize security, self-hosting, and developer workflows over out-of-the-box video calling. It excels in messaging, file sharing, and integrations, especially in tech teams. However, built-in audio/video conferencing is limited without plugins or federation via Mattermost Plugin for WebRTC. If your team can compromise on integrated calling or supplement it externally, Mattermost offers strong privacy and customization. It's ideal for organizations that value control and extensibility over convenience.

Ihre Microsoft Teams (2026 standalone client)-Dateien öffnen

Mattermost supports general file types (PDF, images, documents) and allows uploading and sharing similar to Teams. However, direct compatibility with Microsoft Teams-specific export formats or archived chats is not supported. You can't open .teams files or export data from Teams into Mattermost automatically. File migration must be manual or scripted. Exporting Mattermost data is possible via APIs or database dumps, but formatting differs significantly.
