The Quickbase App Exchange is accessible from within the Quickbase platform where customers can find applications and app templates provided by Quickbase, Quickbase partners, and other customers. It has hundreds of documented sample apps for download and inspiration. Additionally, customers can find and consume reusable composite components (e.g. tables with reports, schema and logic) that are published to the App Exchange.
To use an application from the Exchange, deployment is as simple as selecting the app you want and downloading into your environment. At that point, the application is now fully owned and managed by the user that downloaded it. From there, you can make changes to customize to your needs, or use the application as is.
