Their home page says:

> Lightning web components are custom elements built using HTML and modern JavaScript.

> The Lightning Web Components UI framework uses core Web Components standards and provides only what’s necessary to perform well in browsers. Because it’s built on code that runs natively in browsers, the framework is lightweight and delivers exceptional performance. Most of the code you write is standard JavaScript and HTML.

> Build apps anywhere, any way. You can build an app with your favorite tools, like Webpack, TypeScript, and Babel, and run it on Heroku, Google, or anywhere else. You can also package an app to create a desktop experience in Electron.

Which I think is equivalent to just saying this:

> Lightning Web Components is a lightweight, cross platform, and framework-independent web components library that builds on the native Web Components standards to add some convenient functionality.

Beautiful as well :)

The main website is here: http://lwc.dev Some examples here: https://github.com/trailheadapps/lwc-recipes-oss

More coming soon :)

Looks interesting. It would be cool if there was a list of components and live running examples.

I only know because I happened to be looking at this yesterday, but stopped since it wasn't open source. https://developer.salesforce.com/docs/component-library/over...
