Giving it a go.
Up until this point, for static-site-generators (ssg), I have been using Jekyll. My only two problems with it is that it is Ruby based and I could not find a way for non-technical site owners to edit the site.
Enter NetlifyCMS and GatsbyJS. Getting up and going was not exactly smooth, but I remember having issues when I first started with Jekyll. The added bonus of this pair is that Netlify provides basic forms, which was another problem with SSG sites and one that I solved with Formspree.
Overall, so far so good, especially since I have never touched React before.
