Pushpin is a proxy server that pins client connections open, making it easy to build realtime API endpoints.

Pushpin supports HTTP streaming, HTTP long-polling, and WebSockets. For compatibility with older browsers, it can also translate from SockJS.
Clients communicate using your API contract. Pushpin is a server-side implementation detail. An existing realtime API can be migrated to or away from Pushpin without breaking clients.
Since Pushpin is a proxy server, the backend can be written in any language. Convenience libraries are available to make integration easy.
With Pushpin, API management systems can manage realtime endpoints. Authentication, analytics, etc. work as you'd expect.
Make an HTTP streaming endpoint in 5 minutes:
No need to write a separate backend in a different language just for realtime.
Forget centralized message brokers. Give each microservice its own Pushpin instance.
Pushpin keeps track of state so you don't have to. This works great with serverless backends, too.
Pushpin is horizontally scalable. When you need to grow, just add more instances.
“Pushpin enables us to keep HTTP requests open for streaming at scale.”
