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.Starting Price: Free -

Servo
Servo
Servo’s mission is to provide an independent, modular, embeddable web engine, which allows developers to deliver content and applications using web standards. Servo is written in Rust, and shares code with Mozilla Firefox and the wider Rust ecosystem. Since its creation in 2012, Servo has contributed to W3C/WHATWG web standards by reporting specification issues and submitting new cross-browser automated tests, and core team members have co-edited new standards that have been adopted by other browsers. As a result, the Servo project helps drive the entire web platform forward while building on a platform of reusable, modular technologies that implement web standards. Pre-built nightly snapshots allow developers to try Servo and report issues without building Servo locally. Now that we’ve released our first developer preview, we’ll be investing in formal security audits and improving our security practices using both existing libraries and Rust.Starting Price: Free -
