Parrot is an extensible macOS instant messaging architecture and app. It currently features a reverse-engineered API for Google Hangouts, done by Tom Dryer, with scaffolding around it for multifaceted use. In the future, Facebook Messenger, custom Jabber, WhatsApp, and more protocols may be supported, depending on API availability (or reverse engineering).

• Tom Dryer, for reverse-engineering the Hangouts protocol in hangups
• Peter Sobot, for the initial translation and development of Hangover, a Swift port of hangups, which was used as the initial code base for Parrot's Hangouts component.
