Zendesk Support system requirements

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

Make sure your computer meets or exceeds the minimum hardware requirements for your operating system (Windows or Mac OS X). See the Microsoft or Apple website for the requirements.

Zendesk Support is tested the following Web 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.

For the use of GoodData, you must have at least 1GB or more of RAM available and the ability to support all of the user interface browsers listed below. For a full list of GoodData requirements see, GoodData system requirements.

Some firewall configurations can interfere with access to/from Zendesk Public IP addresses. For configuration suggestions, see Configuring your firewall for use with Zendesk. 

Tip: Our testing suggests that Google Chrome provides the best performance when running Zendesk.

For the agent/administrator user interface:

• Google Chrome: latest two versions
• Mozilla Firefox: latest two versions
• Apple Safari: latest two versions
• Microsoft Internet Explorer: latest version only

  Microsoft Edge is not supported by Zendesk, but reportedly works well for customers.

Browser configuration:

• JavaScript must be enabled
• Cookies must be enabled
• localStorage must be enabled

• Zendesk Support for iPhone: iOS 9.0 and higher

Note: Viewing the agent interface through a mobile browser is not supported. Instead, you need to use one of our mobile apps.
