Astro isn’t solving the same surface as next. Astro is great for static sites with some dynamic behavior. The same could be said about next depending on how you write your code, but next can also be used for highly dynamic websites. Using Astro for highly dynamic websites is like jamming a square peg into a round hole.

We use Astro for our internal dev documentation/design system and it’s awesome for that.

Astro is not a static site builder.
