What's the simplest stack for a beginner to vibe code a web app with user logins and a database, and where can I deploy

For a beginner looking to "vibe code"—meaning you want to describe your features and let the AI do the heavy lifting while you focus on the logic—the simplest path is the "Full-Stack Framework" approach.

Here is the most efficient stack and deployment route:

The Recommended Stack: Next.js + Supabase

• Next.js (Framework): It handles both the frontend and the API (backend) in one place. Using the "App Router" makes it very intuitive to connect components to data.
• Supabase (Database & Auth): Think of this as the "easy button" for your backend. It provides a ready-to-use database (PostgreSQL) and handles all the messy logic of user logins, passwords, and sessions for you.

Why this combination? You don’t have to write custom authentication code (which is hard and risky to build from scratch). Supabase gives you a simple JavaScript client where you just call supabase.auth.signIn() or signUp().

Where to Deploy for Free

Both of these services offer generous "Free Tiers" designed for side projects and learning:

1. Vercel (for the App): This is the company that created Next.js. You can connect your GitHub repository, and it will automatically deploy your site whenever you push code.
2. Supabase (for the Database/Auth): They provide a free hosted PostgreSQL database and authentication service that integrates perfectly with your Next.js app.

The "Vibe Coding" Workflow

To get this off the ground without getting stuck in documentation:

1. Initialize: Use your AI assistant to generate a standard "Next.js with Tailwind CSS" project.
2. Auth: Ask your AI assistant to "Set up authentication boilerplate using Supabase." It will provide the specific code snippets for your login and signup pages.
3. Data: When you need a database table, just tell the AI: "Create a database schema for a todo list app with columns for title, user_id, and completed status, and show me the Next.js code to fetch and add these items."
4. Connect: Use Vercel’s environment variables to keep your Supabase API keys secret.

A Gentle Reminder

While this stack is powerful, remember to keep an eye on your database usage as you grow. Both Vercel and Supabase have simple dashboards where you can see your traffic.
