DocRaptor
Expected Behavior
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.Starting Price: $15 per month -

blanket.js
Blanket.js
A seamless JavaScript code coverage library. Blanket.js is a code coverage tool for JavaScript that aims to be easy to install, easy to use, and easy to understand. Blanket.js can be run seamlessly or can be customized for your needs. JavaScript code coverage compliments your existing JavaScript tests by adding code coverage statistics (which lines of your source code are covered by your tests). Parsing the code using Esprima and node-falafel, and instrumenting the file by adding code tracking lines. Connecting to hooks in the test runner to output the coverage details after the tests have been completed. A Grunt plugin has been created to allow you to use Blanket like a "traditional" code coverage tool (creating instrumented copies of physical files, as opposed to live-instrumenting). Runs the QUnit-based Blanket report headlessly using PhantomJS. Results are displayed on the console, and the task will cause Grunt to fail if any of your configured coverage thresholds are not met.Starting Price: Free -

Karma
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.Starting Price: Free -

Selenium
Software Freedom Conservancy
Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well. If you want to create robust, browser-based regression automation suites and tests, scale and distribute scripts across many environments, then you want to use Selenium WebDriver, a collection of language specific bindings to drive a browser - the way it is meant to be driven. If you want to create quick bug reproduction scripts, create scripts to aid in automation-aided exploratory testing, then you want to use Selenium IDE; a Chrome and Firefox add-on that will do simple record-and-playback of interactions with the browser. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point. -

Phantom
Intelligent Waves
The Phantom Next Generation, award-winning solution provides the ability for organizations to access foreign points of presence to conduct remote open-source information gathering and research while at the same time protecting organizations and individuals from exposure to foreign intelligence. Intelligent Waves has achieved this by combining the GRAYPATH software-defined obfuscated network with the managed attribution capability of the Phantom platform in a secure but unclassified package. The system uses all the capability of the GRAYPATH network to provide low probability of detection, intercept, and exploitation of application traffic and obfuscate the user’s location while the Phantom platform matches the user’s digital signature with the intended point of presence. The user’s true IP, location, and data usage are obfuscated while user-generated traffic is made to “originate” from a remote point of presence (PoP) or interface server. -

It stores apps, bookmarks and browsing history which can be synced between devices using Webian Home. Previously Webian Shell has used XULRunner, Mozilla Chromeless and B2G from Mozilla, but all of these projects have now been discontinued. Gecko is no longer seen as a platform for building applications, just the back end of Firefox. During the transition of B2G to the community, I thought it would be possible for me to continue using B2G OS as a base, using the new simplified architecture we had created with a split between system chrome and system web services.Starting Price: Free -

WebGL
KHRONOS
OpenGL ES for the Web. WebGL is a cross-platform, royalty-free web standard for a low-level 3D graphics API based on OpenGL ES, exposed to ECMAScript via the HTML5 Canvas element. Developers familiar with OpenGL ES 2.0 will recognize WebGL as a Shader-based API using GLSL, with constructs that are semantically similar to those of the underlying OpenGL ES API. It stays very close to the OpenGL ES specification, with some concessions made for what developers expect out of memory-managed languages such as JavaScript. WebGL 1.0 exposes the OpenGL ES 2.0 feature set; WebGL 2.0 exposes the OpenGL ES 3.0 API. WebGL brings plugin-free 3D to the web, implemented right into the browser. Major browser vendors Apple (Safari), Google (Chrome), Microsoft (Edge), and Mozilla (Firefox) are members of the WebGL Working Group.

WebRTC
WebRTC
With WebRTC, you can add real-time communication capabilities to your application that works on top of an open standard. It supports video, voice, and generic data to be sent between peers, allowing developers to build powerful voice- and video-communication solutions. The technology is available on all modern browsers as well as on native clients for all major platforms. The technologies behind WebRTC are implemented as an open web standard and available as regular JavaScript APIs in all major browsers. For native clients, like Android and iOS applications, a library is available that provides the same functionality.

Basilisk
Basilisk
A XUL-based web browser demonstrating the Unified XUL Platform (UXP). This browser is a close twin to pre-Servo Firefox in how it operates. Basilisk is a free and Open Source XUL-based web browser, featuring the well-known Firefox-style interface and operation. It is based on the Goanna layout and rendering engine (a fork of Gecko) and builds on the Unified XUL Platform (UXP), which in turn is a fork of the Mozilla code base without Servo or Rust. Basilisk is primarily a reference application for the development of the XUL platform it builds upon, and additionally a potential replacement for Firefox. Basilisk is development software. This means that it should be considered more or less "beta" at all times; it may have some bugs and is provided as-is, with potential defects. Like any other free software community project, it comes without any warranty or promise of fitness for any particular purpose.Starting Price: Free -
