React primitives render to native platform UI, meaning your app uses the same native platform APIs other apps do. Many platforms, one React. Create platform-specific versions of components so a single codebase can share code across platforms. With React Native, one team can maintain two platforms and share a common technology—React. React Native lets you create truly native apps and doesn't compromise your users' experiences. It provides a core set of platform agnostic native components like View, Text, and Image that map directly to the platform’s native UI building blocks.Starting Price: Free -

Built with compatibility in mind, we embrace our bootstrap core and strive to be compatible with the world's largest UI ecosystem. By relying entirely on the Bootstrap stylesheet, React-Bootstrap just works with the thousands of Bootstrap themes you already love. The React component model gives us more control over form and function of each component. Each component is implemented with accessibility in mind. The result is a set of accessible-by-default components, over what is possible from plain Bootstrap.Starting Price: Free -

Semantic UI React
Vercel
Semantic UI React is the official React integration for Semantic UI. jQuery-free, declarative API, augmentation, shorthand props, sub-components, auto controlled state. jQuery is a DOM manipulation library. It reads from and writes to the DOM. React uses a virtual DOM (a JavaScript representation of the real DOM). React only writes patch updates to the DOM, but never reads from it. It is not feasible to keep real DOM manipulations in sync with React's virtual DOM. Because of this, all jQuery functionality has been re-implemented in React. Control the rendered HTML tag, or render one component as another component. Extra props are passed to the component you are rendering as. Augmentation is powerful. You can compose component features and props without adding extra nested components. Shorthand props generate markup for you, making many use cases a breeze. All object props are spread on the child components.Starting Price: Free -

React
React
React makes it painless to create interactive UIs. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. Declarative views make your code more predictable and easier to debug. Build encapsulated components that manage their own state, then compose them to make complex UIs. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep state out of the DOM. We don’t make assumptions about the rest of your technology stack, so you can develop new features in React without rewriting existing code. React components implement a render() method that takes input data and returns what to display. This example uses an XML-like syntax called JSX. Input data that is passed into the component can be accessed by render() via this.props.Starting Price: Free -

Placing access authority in the hands of end users may seem counterintuitive to an organization’s identity management protocol, but given the right tool, such as ReACT, this practice actually improves security standards. ReACT frees the help desk from password-related tasks and enables end users to solve their password-related problems, improving employee satisfaction, productivity output, and the company bottom line. ReACT automates the password reset and synchronization process. -

Cygwin
Cygwin
Get that Linux feeling on Windows. Cygwin is a large collection of GNU and open-source tools that provide functionality similar to a Linux distribution on Windows. And a DLL (cygwin1.dll) that provides substantial POSIX API functionality. Cygwin is not a way to run native Linux apps on Windows. You must rebuild your application from the source if you want it to run on Windows. It can't magically make native Windows apps aware of UNIX® functionality like signals, ptys, etc. Again, you need to build your apps from source if you want to take advantage of Cygwin functionality. The Cygwin DLL currently works with all recent, commercially released x86_64 versions of Windows, starting with Windows Vista. Use the setup program to perform a fresh install or to update an existing installation. Keep in mind that individual packages in the distribution are updated separately from the DLL so the Cygwin DLL version is not useful as a general Cygwin distribution release number.Starting Price: Free -
