Wix allows you to extend a site's functionality and customize it to fit your needs. You can handle a site's data using the CMS collections. You can also add custom code to a site using the SDK.
Different sites require different amounts of resources, depending on the complexity and volume of their code and data use. Wix offers a number of premium plans that include different levels of data, computing, and developer features. This way, you can choose exactly what you need for a site, depending on its complexity and specific needs.
To better understand what premium features are available, check out:
Compare the resources included in each plan and find the one that's right for you.
You can also try out many of the premium features for free. Find out more about developing on a free Wix site.
Note: Premium plans added to sites before September 2023 are now considered legacy plans. If you have a site with a legacy plan, the site's resource limits won't change. Learn more about legacy plan limits.
