Zulip's default video chat provider is Jitsi Meet.

You can also use Zulip with Jitsi Meet on-premise; to configure this, just set JITSI_SERVER_URL in /etc/zulip/settings.py.

Using Big Blue Button as a video chat provider is currently only possible on self-hosted Zulip installations. See the detailed configuration instructions.

Zulip supports Zoom as the video chat provider using an OAuth integration. You can set it up as follows:

1. Go to Organization settings.

2. Under Other settings set Video chat provider to Zoom.

3. Click Save changes.

Any user who creates a video call link using the instructions above will be prompted to link a Zoom account with their Zulip account.

If you would like to unlink Zoom from your Zulip account:

1. Log in to the Zoom App Marketplace.

2. Click Manage → Installed Apps.

3. Click the Uninstall button next to the Zulip app.

If you are self-hosting, you will need to create a Zoom application to use this integration.

You can also disable the video call button for your organization by setting the provider to "None".
