I tried Bolt v2: Here's why it's better than Lovable and Replit

Bolt 2.0 is a game changer for building full-stack applications fast. In this video, I show how you can go from idea to a working React Native app with authentication, database, and hosting - all generated and deployed by Bolt’s AI-powered Cloud Code. No manual backend setup or juggling multiple services like Supabase, Vercel, or Stripe.

I demonstrate building a site for sharing Snap AI-generated icons with user submissions and approvals. Bolt 2.0 handles authentication, database migrations, environment variables, and deployment seamlessly. This tutorial is for React Native developers curious about accelerating full-stack projects with AI and modern tooling.

Changing perceptions: building full-stack apps faster

Most developers think building a full-stack app requires weeks of coding and complex setup. Bolt 2.0 flips that by letting you generate backend and frontend code in one sitting using natural language prompts. You don’t need to configure DNS, servers, or multiple services manually.

I explain how Bolt abstracts away the hard parts of backend management so you can focus on your idea. Even if you’re not a professional coder, Bolt’s AI agent helps you build real apps with authentication, databases, and hosting. For developers, it acts as an amplifier to prototype and ship faster.

Using Bolt 2.0 with Cloud Code and AI agents

Bolt 2.0 introduces Cloud Code with AI agent integration. You choose an agent like the new Cloud Agent (recommended) or legacy versions. The Cloud Agent runs on the web and generates higher-quality code following best practices, though it takes a bit longer.

I show how to create a Bolt account and start prompting the agent to build a simple React Native app with Tailwind CSS styling. The agent remembers previous work, so you can incrementally add features instead of trying to do everything at once.

Adding authentication and database with Supabase

Bolt 2.0 integrates Supabase for authentication and database management without requiring you to create Supabase accounts or configure anything manually. You just prompt Bolt to add authentication and a users table.

The AI agent generates the backend code and updates the UI to include login and signup screens. I demonstrate signing up and signing in on the generated app, with user data automatically stored in the Supabase database table.

Deploying and managing your app with Bolt Cloud

Deploying is as simple as pressing a publish button in Bolt. The app is deployed to a generated domain, which you can customize later. Every time you make changes, you prompt Bolt to redeploy, and it updates the same domain seamlessly.

I highlight how Bolt sends a notification sound when deployment finishes, letting you take breaks while it works. This smooth deployment experience removes the usual headaches of backend hosting and domain management.

Iterative development and UI refactoring with Bolt prompts

Bolt encourages iterative development by letting you prompt the AI agent to refactor UI or add new features step-by-step. For example, I ask Bolt to refactor the UI so login is optional and only required for users submitting icons.

This approach keeps the project manageable and lets you build complex apps incrementally. Bolt’s enhanced prompt tool can polish your instructions, but I found sending simple prompts works well too.

Managing user submissions and approvals in the database

For the Snap AI icon showcase, I prompt Bolt to add a submissions table and approval system. This lets users submit icons with metadata like download links, prompts used, GitHub profiles, and websites.

Approvals are manual to ensure only legit submissions appear. Bolt generates the necessary database migrations and backend logic to support this workflow, making it easy to manage user-generated content securely.

Showcasing Snap AI icons with dynamic data loading

I demonstrate how to use the Snap AI repo’s test icon URLs to populate the initial showcase on the site. Bolt generates code to fetch and display these icons dynamically using Tailwind CSS for styling.

This creates a polished frontend that highlights community creations and invites users to contribute their own icons. The integration between Bolt backend and frontend code is seamless.

Benefits of Bolt’s enhanced prompt tool and workflow

Bolt includes an enhanced prompt tool to help you refine instructions for the AI agent. While useful, I found that straightforward prompts often suffice.

The overall workflow with Bolt 2.0 feels like having an invisible DevOps engineer managing your backend, letting you focus on building and iterating your app quickly. It’s a powerful tool for React Native developers wanting to ship full-stack apps without the usual complexity.
