Strengths
  • Generate a complete full-stack application (front-end + back-end + database)
  • Run directly in the browser, no local environment required
  • Supports mainstream technology stacks such as React, Vue, Svelte, and Node.js
  • Generated code can be modified and previewed in real time
  • One-click deployment to platforms such as Netlify
Best for
  • Quickly generate an MVP (minimum viable product)
  • Full stack web application prototyping development
  • Learn practical projects for full-stack development
  • Quickly build tool applications (such as calculators, converters)
  • Build a complete application with backend API

Build full-stack applications

Bolt.new can generate a complete application including front-end, back-end and data storage in one go.

Scenario

Build a task management application

Prompt example
Create a full-stack todo app with:
- React frontend with a clean UI
- Node.js/Express backend
- SQLite database for persistence
- Features: Add, edit, delete, mark complete
- Filter by status (All/Active/Completed)
- Due date support
- Priority levels (Low/Medium/High)
- Local storage fallback
Output / what to expect

Bolt.new generates a complete full-stack application:

  • React frontend (with state management)
  • Express REST API (CRUD interface)
  • SQLite database (automatically creates table structure)
  • Complete UI interaction Runs directly in the browser and is ready to use.
Tips

The description contains specific functional requirements and technology stack, and the generated application is more in line with expectations.

Scenario

Generate a web application with authentication

Prompt example
Build a simple blog platform with:
- User authentication (register/login/logout)
- Create, read, update, delete blog posts
- Markdown support for post content
- Tags and categories
- Public posts visible to all, private posts for author only
- React + Vite frontend
- Express backend with JWT auth
Output / what to expect

Generate a blog platform containing a complete authentication system:

  • JWT login/registration process
  • Article CRUD operations
  • Markdown rendering
  • Permission control (public/private) The code structure is clear and can be used as a reference for learning projects.
Tips

Bolt.new generates a relatively complete authentication process and is suitable for learning how to implement JWT authentication.
