Simply Static is a static site generator that converts your existing WordPress website to a static website that you can host on your server, a static hosting provider, or a CDN.
It drastically improves the performance of your website and minimizes security risks as it removes the connection between your traditional server and your static website.
Simply Static can also be used by local development tools like LocalWP or Lando to develop your website offline and push the static site online.
