Moderating open organizations

An open organization is one where anyone can join without an invitation. Moderation is a big part of making an open community work.


Zulip has many features designed to simplify moderation by preventing problematic behavior.

Manage new users

Restrict permissions for making changes

Minimize spam


The following features are an important part of an organization's playbook when responding to abuse or spam that is not prevented by the organization's policy choices.

Public access option

The public access option lets administrators configure selected channels to be web-public. Web-public channels can be viewed by anyone on the Internet without creating an account in your organization.

For example, you can link to a Zulip topic in a web-public channel from a GitHub issue, a social media post, or a forum thread, and anyone will be able to click the link and view the discussion in the Zulip web application without needing to create an account.

To see this feature in action, you can view web-public channels in the Zulip development community without logging in.

Users who wish to post content will need to create an account in order to do so.

Zulip communities directory

The Zulip communities directory offers publicly accessible Zulip Cloud organizations an opportunity to be listed on the Zulip website. It's a way for open-source projects, research communities, and others to advertise their Zulip community and support the Zulip project.

The directory will display your community's name, logo, and a link to you Zulip chat. Other information from your organization profile and the size of your organization may be included as well.

For details on how to get your community listed, see Communities directory.
