Customize Zulip

Once you've got Zulip setup, you'll likely want to configure it the way you like.

Making changes

Most configuration can be done by a realm administrator, on the web. For those settings, see the documentation for realm administrators.

This page discusses additional configuration that a system administrator can do. To change any of the following settings, edit the /etc/zulip/settings.py file on your Zulip server, and then restart the server with the following command:

su zulip -c /home/zulip/deployments/current/scripts/restart-server

Specific settings

Authentication Backends

AUTHENTICATION_BACKENDS is a list of enabled authentication mechanisms. By default the email backend is enabled.

If you want an additional or different authentication backend, you will need to uncomment one or more and then do any additional configuration required for that backend as documented in the settings.py file. See the section on Authentication for more detail on the available authentication backends and how to configure them.

Mobile and desktop apps

The Zulip apps expect to be talking to to servers with a properly signed SSL certificate, in most cases and will not accept a self-signed certificate. You should get a proper SSL certificate before testing the apps.

Because of how Google and Apple have architected the security model of their push notification protocols, the Zulip mobile apps for iOS and Android can only receive push notifications from a single Zulip server. We have configured that server to be push.zulipchat.com, and offer a push notification forwarding service that forwards push notifications through our servers to mobile devices. Read the linked documentation for instructions on how to register for and configure this service.

By the end of summer 2017, all of the Zulip apps will have full support for multiple accounts, potentially on different Zulip servers, with a convenient UI for switching between them.

Terms of Service and Privacy policy

Zulip allows you to configure your server's Terms of Service and Privacy Policy pages (/terms and /privacy, respectively). You can use the TERMS_OF_SERVICE and PRIVACY_POLICY settings to configure the path to your server's policies. The syntax is Markdown (with support for included HTML). A good approach is to use paths like /etc/zulip/terms.md, so that it's easy to back up your policy configuration along with your other Zulip server configuration.

Miscellaneous server settings

Zulip has dozens of settings documented in the comments in /etc/zulip/settings.py; you can review the latest version of the settings.py template if you've deleted the comments or want to check if new settings have been added in more recent versions of Zulip.

Since Zulip's settings file is a Python script, there are a number of other things that one can configure that are not documented; ask on chat.zulip.org if there's something you'd like to do but can't figure out how to.

Some popular settings in /etc/zulip/settings.py include:

  • The Twitter integration, which provides pretty inline previews of tweets.
  • The email gateway, which lets users send emails into Zulip.
  • INLINE_URL_EMBED_PREVIEW, which controls our experimental feature providing inline previews of links pasted into Zulip.

If you discover things that you wish had been documented, please contribute documentation suggestions either via a GitHub issue or pull request; we love even small contributions, and we'd love to make the Zulip documentation cover everything anyone might want to know about running Zulip in production.
