Change organization URL

Zulip supports changing the URL for an organization. Changing the organization URL is a disruptive operation for users:

• Users will be logged out of existing sessions on the web, mobile and desktop apps and need to log in again.
• Any API clients or integrations will need to be updated to point to the new organization URL.

We recommend using a wildcard mention in an announcement channel to notify users that they need to update their clients.

Change your Zulip Cloud subdomain

Zulip Cloud organizations are generally hosted at <subdomain>.zulipchat.com, with the subdomain chosen when the organization was created. Organization owners can request to change the subdomain.

Move to a custom URL on Zulip Cloud

Because maintaining custom URLs requires effort from our operational team, this feature is available only for organizations with 25+ Zulip Cloud Plus licenses.

Change the URL for your self-hosted server

If you're self-hosting, you can change the root domain of your Zulip server by changing the EXTERNAL_HOST setting. If you're hosting multiple organizations and want to change the subdomain for one of them, you can do this using the change_realm_subdomain management command.

In addition to configuring Zulip as detailed here, you also need to generate SSL certificates for your new domain.
