Build Status CoverageStatus License

Artax is an asynchronous HTTP client for PHP based on Amp. Its API simplifies standards-compliant HTTP resource traversal and RESTful web service consumption without obscuring the underlying protocol. The library manually implements HTTP over TCP sockets; as such it has no dependency on ext/curl.


  • Requests asynchronously for full single-threaded concurrency
  • Pools persistent keep-alive connections
  • Transparently follows redirects
  • Decodes gzipped entity bodies
  • Exposes headers and message data
  • Streams entity bodies for memory management with large transfers
  • Supports all standard and custom HTTP method verbs
  • Simplifies HTTP form submissions
  • Implements secure-by-default TLS (https://)
  • Supports cookies and sessions
  • Functions seamlessly behind HTTP proxies

Project Goals

  • Model all code as closely as possible to the relevant HTTP protocol RFCs
  • Implement an HTTP/1.1 client built on raw socket streams with no libcurl dependency
