ZingChart: Who should buy a website license?
The website license is our most basic license, intended for users that plan to display charts on a publicly accessible website or blog. Visitors should not have to login to access the site or any of the charts. (If they do, you should consider the Internal or SaaS license.) Website licenses are generally used for sites that are informational in nature, and should not be associated with the distribution or sale of a product.
Each license is for use on a single domain. You can buy additional licenses for additional domains. Users that require product support hours can purchase them through the Pricing page. For more detailed information, see the website license page.
