Pushpin, a reverse proxy for real-time web services

In plain words

Pushpin is a reverse proxy server that adds push capabilities to existing APIs, enabling real-time web services.

The tool is designed for backend engineers and DevOps teams who need to add real-time communication features to their web infrastructure.
