Plug: Our publishing platform — https://proof.pub — combines an editorial suite, API-based CMS, and Javascript/Sass SDK for creating static compilers using server-side React. When content is released through the editorial suite, we perform a static compilation and push the resulting archive to CloudFront. Works great, sites load quickly, and it all scales very simply.

A real-world example would be the First Round Review (http://firstround.com/review/), designed by our studio (https://marquee.studio) and running on Proof.
