Had to use Zeit/Vercel a few months for a “serious” project that requires SSR, caching and multiple staging environments. As the project progresses I noticed an increasing pain from constantly fighting with outdated documentations and limited configurability. I hope that’s changed now though, because there were some parts of Zeit that we loved. For simpler static sites, it’s hard to beat Netlify.
the docs could definitely use some work. there's a ton of nuance in advanced nextjs apps and the docs usually have the answer i am looking for, but it's tough to find it
