Pushpin is a reverse proxy server that makes it easy to implement WebSocket, HTTP streaming, and HTTP long-polling services. It communicates with backend web applications using regular, short-lived HTTP requests (GRIP protocol). This allows backend applications to be written in any language and use any webserver.

Additionally, Pushpin does all of this without exposing a proprietary protocol to clients. The HTTP/WebSocket content between the client and your server is whatever you want it to be. This makes it ideal for implementing APIs.
