Async Perl. Real-time protocols. One interface.
PAGI (Perl Asynchronous Gateway Interface) is a modern async successor to PSGI, designed for HTTP plus real-time protocols like WebSocket and Server-Sent Events (SSE).
PAGI apps use an event-based interface with explicit backpressure (Futures), so streaming responses and long-lived connections are natural and predictable under load.
- One interface for HTTP, WebSocket, SSE, and lifespan (startup/shutdown)
- Reference server plus router and middleware ecosystem
- Legacy compatibility via PSGI bridging (WrapPSGI)
