Zulip ou Slack : une bonne alternative sous Linux ?

Zulip, alternative Linux à Slack

Mis à jour le 20 octobre 2026

Notre avis

Zulip is a strong, honest replacement for Slack, particularly for teams that find Slack’s flat message streams chaotic. It excels at organizing high-volume discussions through mandatory threading, which keeps context intact. While it lacks some of Slack’s polished integrations out of the box, its open-source nature allows for deep customization and self-hosting. If your team values structured conversation over quick, fragmented pings, Zulip will feel like an upgrade. It is less suitable for casual, low-volume chat where immediate, unthreaded responses are preferred.

Zulip enforces threaded conversations, whereas Slack allows flat streams
Zulip is open-source and self-hostable, while Slack is a proprietary cloud service

Zulip’s interface is more text-heavy and focused on readability, unlike Slack’s visual-heavy design

Ouvrir vos fichiers Slack

Zulip does not natively open Slack-specific file formats or archive structures. You will need to export data from Slack using their built-in export tools (usually CSV or JSON) and then manually import or reference those files within Zulip. There is no direct, one-click migration path for file attachments; you must re-upload or link them to the new environment.
