# About Premium Plans

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](https://support.wix.com/en/article/about-the-content-manager-7160473) collections. You can also add custom code to a site using the [SDK](https://dev.wix.com/docs/sdk.md).

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:

- [Data platform](https://dev.wix.com/docs/develop-websites-sdk/maintain-your-site/scale-your-site/about-data-feature-limitations.md)
- [Compute platform](https://dev.wix.com/docs/develop-websites-sdk/maintain-your-site/scale-your-site/about-compute-feature-limitations.md)
- [Developer tools](https://dev.wix.com/docs/develop-websites-sdk/maintain-your-site/scale-your-site/about-developer-tool-feature-limitations.md)

[Compare](https://www.wix.com/upgrade/website) 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](https://dev.wix.com/docs/develop-websites-sdk/maintain-your-site/scale-your-site/about-code-on-free-sites.md).

> **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.
