What's the best alternative?

I have used Gridsome for many years without any problems. But the last week Netlify won't build my solution anymore cause som strange error / old version of packages used in Gridsome. Sadly I have to look for another solution. So what is the best static HTML generator as an alternative to Gridsome?

I know both Vue and React. I use Sanity as "CMS" and would like to continue to do so.
