Rocket.Chat vs. Slack: eine gute Linux-Alternative?

Rocket.Chat als Linux-Alternative zu Slack

Aktualisiert am 20. Oktober 2026

Unser Fazit

Rocket.Chat is a strong, self-hostable alternative to Slack, ideal for teams prioritizing data sovereignty and avoiding per-seat costs. It covers core needs like channels, threads, and file sharing effectively. However, its integration ecosystem is smaller than Slack's, so you may need to build custom bots for specific CI/CD or calendar tools. If you can manage a server or use their cloud, it is a viable, cost-effective replacement. For companies deeply embedded in the Slack API ecosystem, the migration effort might outweigh the savings unless security or cost are critical drivers.

Ihre Slack-Dateien öffnen

Rocket.Chat does not natively open Slack-specific file formats or archives. You will need to manually export files from Slack (via workspace export settings) and upload them to Rocket.Chat. Direct import of Slack message history is not built-in; you would need a third-party script or manual copy-pasting for text, which is tedious for large workspaces. File formats like PDF, images, and Office documents work identically in both platforms.

Von Slack zu Rocket.Chat wechseln – Schritt für Schritt

Set up a Rocket.Chat instance (self-hosted or cloud) and configure SSO/MFA to match Slack security policies.
Create channel structures in Rocket.Chat that mirror your existing Slack workspace organization.
Export Slack data using the workspace export feature to get a JSON/CSV archive of messages and files.
Use a community script or manual method to import message history and attach exported files to relevant channels.
Install necessary integrations via Rocket.Chat’s API or marketplace to replace key Slack apps (e.g., Git, CI notifications).
Communicate the switch to your team, provide login credentials, and disable Slack access after a transition period.

Häufige Fragen

Is Rocket.Chat free to use?

Yes, the open-source version is free under the MIT license. You can self-host it for free, or use their cloud service which may have paid tiers for managed hosting and support.

Can I import my Slack history automatically?

There is no official one-click importer. You must export from Slack first. Then, use community-driven scripts to parse the export and import messages into Rocket.Chat, though this can be complex for large workspaces.

Does it support video calls?

Yes, Rocket.Chat has built-in video and audio conferencing capabilities, so you do not need a separate tool for basic meetings, though it may not match the polish of dedicated video platforms.
