I'm a little wary of this. I'd been using Gatsby for my static websites for a long time, until it got eaten up by Netlify and then sunset; I switched over to Astro at that point, but now I'm getting a sense of déjà vu.
I had moved out from Gatsby to Astro on my blog/site (username.com), mostly because the enormous dependency hell full of security issues, I know it's just things to generate static files, but it was causing a lot of headaches to upgrade and remove the issues. With Astro, I receive a lot less issues and the maintenance is easier! From my perspective if Cloudflare keep it that way, it'll be a win.
Just setup my personal blog again after a four years hiatus using Astro (loved the good docs). Kind of disappointed, but given how simple static site generators are, probably something Claude could crank out easily with parity of features I actually use then wouldn't be beholden to any project's creators.
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.
