Unlike traditional chat tools, Zulip allows community members to follow multiple ongoing conversations simultaneously without losing context, making it ideal for large communities with diverse discussion topics. The platform supports both self-hosted deployments for full data control and cloud hosting, with specific features for open-source projects, educational communities, and professional associations.
