# Next.js vs SvelteKit
URL: https://wwadd.dev/compare/nextjs-vs-sveltekit
Last verified: 2026-10-12

Both build applications with public server-rendered pages and authenticated features. Start with the UI your team can maintain, then prove the server and deployment behavior your product needs.

## Verdict
Choose Next.js when React and its integrations are product constraints. Choose SvelteKit when the team wants a Svelte application with server routes and progressively enhanced forms. Both can serve indexable HTML; neither removes auth or cache design. Before choosing, deploy one public page and one authenticated mutation with your real dependencies.

## Pick Next.js when
- Your team already maintains React and needs its component integrations alongside public and authenticated routes
- You can test mutations, cache invalidation, and the chosen host's framework support before launch

**Skip Next.js if:** React is not a requirement and your team cannot maintain App Router server/client boundaries and cache behavior.

## Pick SvelteKit when
- Your team prefers Svelte and needs server loads, HTML forms, and route-level rendering choices
- A supported deployment adapter and your required database/auth libraries work in the target runtime

**Skip SvelteKit if:** the product depends on React-only components or integrations that you cannot replace or isolate.

## What actually differs
- UI and application model: Next.js — React components; App Router separates Server Components from interactive Client Components; SvelteKit — Svelte components with route loads, server endpoints, and form actions in SvelteKit
- Public and private pages: Next.js — Combine static and request-time rendering; define cache and revalidation rules for changing data; SvelteKit — Choose prerendering, server rendering, and client rendering per route or layout
- Forms and mutations: Next.js — Server Actions and route handlers; validate input and authorize each server operation; SvelteKit — Server form actions work with HTML forms and optional progressive enhancement; validate and authorize on the server
- Deployment: Next.js — Node.js and Docker support the framework; static export has server-feature limits, and platform integrations vary; SvelteKit — Official adapters target Node, Bun, static hosting, Vercel, Netlify, and Cloudflare; runtime capabilities still differ
- Learning and maintenance: Next.js — Fits a team invested in React; server/client boundaries and caching need deliberate review; SvelteKit — Fits a team invested in Svelte; choose libraries and an adapter that cover the actual product requirements
