Gatsby was sunset because it was a bad framework build on bad decisions [1]. I tried to use it when it was new, and it was immediately obvious that "GraphQL for everything" leads to horrible DX.

It was definitely a terrible DX, I remember having trouble wrapping my head around querying for blog posts inside my blog post component instead of receiving them as props. But I was using a custom F# + asp.net blog engine I'd written for what amounted to a static site, so I just switched to that Gatsby thing I'd been hearing a lot about at the time.
