The STEAM Powered website is built with GatsbyJS and deployed on Netlify. It's fine as an SSG but I haven't figured out a good way to schedule posts to be published.
There's some automation that can be done either through repo hooks or calling the Netlify build endpoint. You can use a cronjob to call the endpoint or use a webservice like cronhooks.io or Zapier to call it on a timer. This is a WIP.
