Overview

What is Zulip?

Zulip is an open-source team messaging platform that stands out for its unique model of organizing conversations by discussion threads (topics). Within each channel, messages are attached to a named topic: discussions remain readable and easy to follow, even in very active organizations.

Zulip combines the best of real-time chat and asynchronous communication, making it a particularly suitable tool for distributed teams, remote workers, or those spread across multiple time zones. It offers powerful search, Markdown support, reactions, file sharing, as well as web, desktop, and mobile apps. Hundreds of integrations, bots, and an open API allow it to connect with GitHub, Jira, your CI/CD pipelines, and the rest of your ecosystem.

Sovereign alternative to Slack and Teams, Zulip is hosted by DINAO in a dedicated container on our French infrastructure: your conversations and files stay in France, and DINAO manages installation, SSO, security, and updates.
