About Custom Apps
Note: Custom apps replace Velo packages built by you. Now, instead of creating packages, functionality is managed as apps.
Custom apps are applications you create using Wix Blocks to add functionality that can be used across multiple Wix sites. Your custom apps are private and only you can install them on sites where you're a site contributor. Once installed, all site contributors can access the functionality of the custom app.
Using custom apps allows you to unify the following functionality across your sites:
- Widgets
- Code
- Dashboard extensions
- Collections
For example, you might use custom apps to do the following across your sites:
- Ensure a standardized visual design.
- Centralize and reuse custom logic and code.
- Add and manage custom dashboard features.
- Use uniform data structures and content setups.
Supported IDEs
You can use and access functionality from your custom apps using:
- The editor (Wix Studio and Wix Editor)
- The Wix IDE
- Your local IDE
Note: You must have a Wix Studio account to create a Blocks app.
Accessing custom app functionality on a site
Install and manage your custom apps, including the version installed on the site, under Custom Apps when you click App Market 
in the Editor.
Once installed, a custom app's functionality is automatically available on your site. To learn how to access the functionality, see Install a Blocks App on a Site.
