Which one should I pick for a new project?

I can help you understand the differences, but the choice depends on your specific needs. Here's what the repositories show:

SvelteKit ([sveltejs/kit]) is described as "web development, streamlined" and is similar to Next.js if you're coming from React, or Nuxt if you're from Vue [documentation/docs/10-getting-started/10-introduction.md:L11-L16]. It's a framework for building robust, performant web applications using Svelte.

Next.js ([vercel/next.js]) is Vercel's React framework with support for both App Router and Pages Router.

Key considerations:

1. Language & Framework: SvelteKit uses Svelte (a compiler-based framework), while Next.js uses React. If you already know one, that's your answer.

2. Maintenance & Stability: SvelteKit shows strong signals — it has a RepoPilot verdict of "GO" with architecture grade A (89/100), zero known CVEs, and 2 circular imports (acceptable). Next.js is a mature, widely-used framework.

3. Ecosystem: Next.js has a larger ecosystem and community support given React's dominance. SvelteKit has official adapters for Vercel, Netlify, Cloudflare, and others [README].

4. Project Requirements: Consider whether you need:

   • Server-side rendering, static generation, API routes
   • Specific hosting platforms (both support many)
   • Team familiarity with the tech stack

Neither is objectively "better" — it depends on your team's skills, project requirements, and deployment target.

• What framework/language does your team know best?
• Where do you plan to deploy your application?
• Do you need real-time features or complex state management?
