# [PhantomJS](http://phantomjs.org) - Scriptable Headless WebKit

PhantomJS ([www.phantomjs.org](http://phantomjs.org)) is a headless WebKit scriptable with JavaScript or CoffeeScript. It is used by hundreds of [developers](http://code.google.com/p/phantomjs/wiki/ExternalArticles) and dozens of [organizations](http://code.google.com/p/phantomjs/wiki/WhoUsesPhantomJS) for web-related development workflow.

The latest [stable release](http://code.google.com/p/phantomjs/wiki/ReleaseNotes) is version 1.5 (codenamed "Ghost Flower"). Follow the official Twitter stream [@HeadlessPhantom](http://twitter.com/HeadlessPhantom) to get the frequent development updates.

PhantomJS is created and maintained by [Ariya Hidayat](http://ariya.ofilabs.com/about) (Twitter: [@ariyahidayat](http://twitter.com/ariyahidayat)), with the help of [many contributors](https://github.com/ariya/phantomjs/contributors).

## Use Cases

- **Headless web testing**. Lightning-fast testing without the browser is now possible! Various [test frameworks](http://code.google.com/p/phantomjs/wiki/TestFrameworkIntegration) such as Jasmine, Capybara, QUnit,  WebDriver, YUI Test, BusterJS, FuncUnit, Robot Framework, and many others are supported.

- **Site scraping**. [Access and manipulate](http://code.google.com/p/phantomjs/wiki/QuickStart#DOM_Manipulation) webpages with the standard DOM API, or with usual libraries like jQuery.

- **Page rendering**. [Capture](http://code.google.com/p/phantomjs/wiki/QuickStart#Rendering) the full contents, even with SVG and Canvas, to an image. Build server-side web graphics apps, from a screenshot service to a vector chart rasterizer.

- **Network monitoring**. [Monitor](http://code.google.com/p/phantomjs/wiki/QuickStart#Network_traffic) network activity, track resource loading, perform load-balancing tests, verify contents optimization, and many others.

## Features

- **Multiplatform**, available on major operating systems: Windows, Mac OS X, Linux, other Unices.
- **Fast and native implementation** of web standards: DOM, CSS, JavaScript, Canvas, SVG. No emulation!
- **Pure headless (X11) on Linux**, ideal for continuous integration systems. Also runs on Amazon EC2.
- **Easy to install**: [Download](http://code.google.com/p/phantomjs/wiki/Installation), unpack, and start having fun in just 5 minutes.
