About ZealPHP

ZealPHP is an async PHP runtime that lets PHP act as the HTTP server for AI web applications. Upgrade existing PHP codebases to coroutine-native concurrency with streaming SSR, WebSocket, SSE, shared memory, and task workers. Built on OpenSwoole and isolated by ext-zealphp, ZealPHP enables server-side streaming of AI tokens, real-time connections, and high throughput without adding separate Node/Go services. (Alpha · v0.4.15)

Key Features

  • Coroutine-native async PHP runtime — PHP acts as the HTTP server
  • Streaming SSR and server-sent events (SSE) for AI token streaming
  • First-class WebSocket support and task workers for real-time apps
  • Shared memory and isolated coroutines via ext-zealphp
  • Built on OpenSwoole with compatibility for existing PHP codebases and PSR-15 middleware

Who is this for?

PHP developers and teams building AI-enabled web apps who want coroutine-native concurrency, streaming, and real-time features without introducing a separate service.
