Gatsby - Blazing fast static site generator for React

Gatsby is a blazing fast static site generator for React. Gatsby.js is a static PWA (Progressive Web App) generator. You get code and data splitting out-of-the-box. Gatsby loads only the critical HTML, CSS, data, and JavaScript so your site loads as fast as possible. Once loaded, Gatsby prefetches resources for other pages so clicking around the site feels incredibly fast.

It has rich data plugin ecosystem lets you build sites with the data you want — from one or many sources: Pull data from headless CMSs, SaaS services, APIs, databases, your file system & more directly into your pages using GraphQL.
