What should I use for a frontend and backend in one place?

If you want frontend + backend in one place, the best choice depends on how much you want to build yourself.

Good all-in-one options

1. Next.js

• Frontend: React
• Backend: API routes / server actions
• Great if you want one codebase for both UI and server logic
• Very popular for full-stack web apps

2. Nuxt

• Frontend: Vue
• Backend: server routes
• Similar idea to Next.js, but for Vue developers

3. SvelteKit

• Frontend: Svelte
• Backend: server endpoints/actions
• Very clean and lightweight

4. Remix

• Frontend + backend in one app
• Strong focus on server-side rendering and forms

If you want the simplest path

• Use Next.js if you’re okay with React
• Use SvelteKit if you want something more lightweight and straightforward
• Use Nuxt if you prefer Vue

If you mean “one platform, not one codebase”

Then consider:

• Firebase
• Supabase
• Appwrite

These give you backend services like auth, database, storage, and sometimes serverless functions, while you build the frontend separately.

My quick recommendation

• For most people: Next.js + Supabase
• For a simpler full-stack app: SvelteKit
• For Vue developers: Nuxt

If you tell me:

1. your skill level,
2. whether you prefer React/Vue/Svelte,
3. what app you’re building,

I can recommend the best exact stack.
