PhantomJS is a headless web browser scriptable with JavaScript. It runs on Windows, macOS, Linux, and FreeBSD.

Using QtWebKit as the back-end, it offers fast and native support for various web standards: DOM handling, CSS selector, JSON, Canvas, and SVG.

The following simple script for PhantomJS loads Google homepage, waits a bit, and then captures it to an image.

var page = require('webpage').create();
page.open('http://www.google.com', function() {
    setTimeout(function() {
        page.render('google.png');
        phantom.exit();
    }, 200);
});

PhantomJS is an optimal solution for:

Page automation
Access webpages and extract information using the standard DOM API, or with usual libraries like jQuery.
Screen capture
Programmatically capture web contents, including SVG and Canvas. Create web site screenshots with thumbnail preview.
Headless website testing
Run functional tests with frameworks such as Jasmine, QUnit, Mocha, WebDriver, etc.
Network monitoring
Monitor page loading and export as standard HAR files. Automate performance analysis using YSlow and Jenkins.
