Hugo is an incredibly fast (<ms1 per page) framework for building static sites, which is highly flexible and works cross-platform. Hugo supports multiple content types, taxonomies, menus, dynamic API-driven content, and more without plugins. It also provides over 100 themes out of the box.

Unlike Gatsby, Hugo with React isn’t an out of the box thing. However, your Hugo blog can live inside a larger React application. Meaning, you can enjoy the superior performance (and SEO) of Hugo inside you React application. Some even combine Hugo with Gatsby. Worth checking out for your site.

7. Phenomic

Phenomic is a framework built to make the SSG experience similar to building a full-blown app: it’s a modular website compiler that lets you bring your own renderer (React), bundler (Webpack) and friends.

It's built for highly SEO-performant websites and a fast UX. While resources in the ecosystem are scarce, the authors did provide a create-react-app blog template and a set of plugins. React users can leverage methods supported via the new withInitialProps HOC, to consume any kind of data (REST APIs, GraphQL APIs for CMS etc) via static async getInitialProps() . This API comes with another new method for the pre-rendering step, called static async getAllPossibleUrls() . Here’s a template for Phenomic with React.

Phenomic is a work in progress, actively developed, and v1 is coming up- so feel free to play around, try it out and keep a close eye on this one.

8.Antwar

Created by the Founder of SurviveJS, Antwar is a “blog-aware” static site engine built with React and Webpack. It’s built to be fast, extensible and friendly. Just like Webpack itself, Antwar is built on top of configurations: antwar.config.js describes how to map your content into a site. It ties layouts to the content and allows you to define custom pages where needed. You can deploy to GitHub pages (and automate via Travis).

This project isn’t very actively maintained and doesn’t have the rich ecosystem of the others, but I still thought it’s worth a mention on the list. Check it out.
