Audience
Web developers interested in a scriptable browser to automate and test web page interactions using JavaScript
About SlimerJS
SlimerJS is a free, open source scriptable browser for web developers, allowing interaction with web pages through external JavaScript scripts. It enables tasks such as opening web pages, clicking links, and modifying content, making it useful for functional tests, page automation, network monitoring, screen capture, and web scraping. Unlike PhantomJS, SlimerJS runs on top of Gecko, the browser engine of Mozilla Firefox, instead of WebKit, and can operate in both headless and non-headless modes. APIs of SlimerJS are similar to the APIs of PhantomJS but there are a few differences in their behavior. However, most of the scripts for PhantomJS run perfectly well with SlimerJS right now.

PhantomJS
PhantomJS is a headless web browser scriptable with JavaScript, running on Windows, macOS, Linux, and FreeBSD. Utilizing QtWebKit as its back-end, it offers fast and native support for various web standards, including DOM handling, CSS selectors, JSON, Canvas, and SVG. This makes it an optimal solution for tasks such as page automation, screen capture, headless website testing, and network monitoring. For example, a simple script can load a webpage and capture it as an image.

Karma
The main goal for Karma is to bring a productive testing environment to developers. The environment being one where they don't have to set up loads of configurations, but rather a place where developers can just write the code and get instant feedback from their tests. Because getting quick feedback is what makes you productive and creative. Test your code on real browsers and real devices such as phones, tablets or on a headless PhantomJS instance. Control the whole workflow from the command line or your IDE - just save a file and Karma will run all the tests. Karma also watches all the files, specified within the configuration file, and whenever any file changes, it triggers the test run by sending a signal to the testing server to inform all of the captured browsers to run the test code again. Each browser then loads the source files inside an IFrame, executes the tests and reports the results back to the server.

trifleJS
TrifleJS is a headless browser designed for test automation, utilizing the .NET WebBrowser class and the V8 JavaScript engine to emulate Internet Explorer environments. Its API is modeled after PhantomJS, making it familiar to users of that framework. TrifleJS supports various versions of Internet Explorer, allowing emulation of IE7, IE8, and IE9, depending on the installed version. Developers can execute scripts via the command line, specifying the desired IE version for emulation. The platform offers an interactive mode (REPL) for debugging and testing JavaScript code.

DocRaptor
There are several popular free HTML-to-PDF libraries including wkhtmltopdf, PhantomJS, and Chrome Headless / Puppeteer. These tools use the Webkit or Chromium rendering engines, which are designed to display continuously scrolling webpages. In contrast, DocRaptor was built for generating multi-page documents. This fundamental difference has a tremendous impact on PDF functionality such as page breaks, headers and footers, and variable page sizes. Our conversion engine provides layout and styling options (including CSS Paged Media support) that the open-source PDF engines simply cannot match. Additionally, as a cloud-based API, we provide professional support, instant scalability, and guaranteed reliability without the costs of long-term maintenance for these libraries and their infrastructure.
