AppServer, a set of components for building fast universal web-apps in PHP

Latest Stable Version

Web server interface for PHP, inspired by Ruby’s Rack and Python’s WSGI. It provides a common API for connecting PHP frameworks and applications to webservers.

The main idea is, that your app, if built for this protocol, will be able to preload resources, preconnect to databases and response to requests really fast.

PHP 5.3+ is required, as it provides garbage collector for cyclic references, which is critical for long-running apps.


The recommended way to install AiP is through Composer. Just create a composer.json file and run the php composer.phar install command to install it:

    "require": {
        "aip/aip": "~0.10.0"


Take a look at example.

  • MyApp.class.php — application class. "__invoke()" method is the entry point
  • aip.yaml — defines that this application should be served both as HTTP and SCGI

run with aip app [path/to/[aip.yaml]] command, test by pointing your browser to
