Next.js

Modern web applications built around React

Next.js combines React with routing, server-side capabilities, performance tooling and flexible rendering strategies. It is one of our preferred foundations for modern SaaS and web applications.

  • The stack serves the product, not the other way around
  • SaaS platforms
  • Customer-facing applications
  • AI applications

Why we use it

Why it earns a place in the stack

  • React ecosystem with excellent developer experience
