Users use many different services on the web to handle their day to day tasks, such as sharing images, editing documents and listening to music. They expect their applications to be connected and to work together seamlessly.

It is impossible for developers to anticipate every new service and to integrate with every existing external service that their users prefer, and thus they must choose to integrate with a few select APIs at great expense to the developer.

Web Intents solves this. Web Intents is a framework for client-side service discovery and inter-application communication. Services register their intention to be able to handle an action on the user's behalf. Applications request to start an Action of a certain verb (share, edit, view, pick etc.) and the system will find the appropriate Services for the user to use based on the user's preference.

Web Intents puts the user in control of service integrations and makes the developer's life simple.
