PhantomJS - Scriptable Headless WebKit

PhantomJS (phantomjs.org) is a headless WebKit scriptable with JavaScript. The latest stable release is version 2.1.

Important: PhantomJS development is suspended until further notice (see #15344 for more details).

Use Cases

• Headless web testing. Lightning-fast testing without the browser is now possible!
• Page automation. Access and manipulate web pages with the standard DOM API, or with usual libraries like jQuery.
• Screen capture. Programmatically capture web contents, including CSS, SVG and Canvas. Build server-side web graphics apps, from a screenshot service to a vector chart rasterizer.
• Network monitoring. Automate performance analysis, track page loading and export as standard HAR format.

Features

• Multiplatform, available on major operating systems: Windows, Mac OS X, Linux, and other Unices.
• Fast and native implementation of web standards: DOM, CSS, JavaScript, Canvas, and SVG. No emulation!
• Pure headless (no X11) on Linux, ideal for continuous integration systems. Also runs on Amazon EC2, Heroku, and Iron.io.
• Easy to install: Download, unpack, and start having fun in just 5 minutes.
