Wix apps are packages of reusable functionality that Wix users can add to their sites. They can contain anything from a simple site widget to a full-stack business solution, complete with backend logic, user interfaces, and databases.
Wix Blocks is an editor for designing, coding, and deploying native Wix apps. It lets you build site and dashboard extensions using Wix’s drag-and-drop editor, with its powerful layout and design tools. For business logic, you write code using the Wix JavaScript SDK. Your code is deployed and hosted on the Wix cloud, with no additional costs or setup by you.
When developing an app with Wix Blocks, you don't need to create a Wix client. Just call the Wix JavaScript SDK's APIs directly and authentication is taken care of for you automatically.
