Zendesk Chat is a web-based SaaS (software as a service) application that runs in a web browser.

Zendesk Chat supports the following browsers running in Windows or Mac OS X. Your browser must be a stable release version, not an Alpha/Beta/Nightly/Development build. This applies to all browsers, regardless of operating system.

If you are using live chat inside of Zendesk Support, you should also check the Zendesk Support system requirements doc.

If you are using a version of live chat integrated with the Web Widget (Classic), check the Web Widget (Classic) requirements for more information.

Firewall configuration

Zendesk Chat only uses ports 80 and 443, which should be open on all firewalls as they are standard ports. The more important thing to look for is the following:

Traffic from *.zopim.com is whitelisted on the firewall. (* is a wildcard and means all subdomains on the zopim.com domain).

Zendesk Chat relies on Amazon for services. If the customer is blocking Amazon IPs, it could negatively impact chat performance.
