Next.js vs. Astro vs. SvelteKit: Core Variations Explained

Before comparing features, let’s quickly define each framework:

Next.js: Next.js, backed by Vercel, enhances React with features like server-side rendering, static generation, and incremental updates through ISR. It’s the go-to choice for large-scale apps and enterprise-level solutions.

Astro: Known as the “content-first” framework, Astro focuses on static site generation and ships zero JavaScript by default, making it incredibly fast and SEO-friendly.

SvelteKit: Built on top of the Svelte compiler, it prioritizes developer experience with minimal boilerplate, lightning-fast performance, and a growing ecosystem for modern web apps.

In short: Next.js = full-stack power, Astro = content/SEO focus, SvelteKit = developer simplicity.
