Pushbullet

Pushbullet is a consumer utility that connects a user's phone, tablet and computer so they can exchange data automatically. Core functionality includes mirroring and dismissing phone notifications on a computer, sending and receiving text messages from a PC, and transferring links, files and text snippets between devices [5][6]. The company describes its mission as bridging the gap between phone, tablet and computer so the devices work better together, addressing the difficulty of sharing data as smartphones and tablets took over users' digital lives [6].

The product is delivered through a set of clients and integrations rather than a single application. Pushbullet ships apps and browser extensions across platforms, plus channels (subscribable push feeds), a Pro tier and a public API [2][3][4]. In January 2015, alongside its seed round, the company announced apps for iOS, Mac and Safari, extending the product from Android and Windows into the Apple ecosystem [5].

The Pushbullet API allows developers to send and receive pushes through Pushbullet's servers and to build unofficial clients. It is an HTTPS/JSON API authenticated with a per-user access token (or OAuth when acting on behalf of another user), supports CORS, and exposes objects such as pushes and devices with list, create, modify and delete operations, cursor-based pagination and standard HTTP status codes. Documented use cases include website push notifications, home automation, sensor messaging and IT/server alerting [4].
