Build Apps Inside Gmail with InboxSDK

The InboxSDK is a high level Javascript library used to easily build browser extensions that interact with both Gmail and Inbox by Google. It provides all of the necessary APIs to create full-fledged applications directly inside Gmail and Inbox. Because the SDK is fully maintained and evergreen, you’ll never be forced to maintain your app.

With InboxSDK, you interact with simple high level classes like ComposeView. You call straightforward methods (like adding buttons or getting the subject) on the class and the SDK abstracts the entire DOM away from you.
