AI App Builder

What is Bolt?

Bolt (available at bolt.new) is an AI-powered full-stack development environment created by StackBlitz, the company behind the pioneering browser-based IDE of the same name. Launched in 2024, Bolt takes a fundamentally different approach to AI-assisted development: instead of adding AI to an existing code editor, it builds the entire development workflow — from scaffolding to deployment — around AI from the ground up. The core idea is simple: describe what you want to build in plain English, and Bolt generates a working application you can immediately preview, edit, and deploy.

What makes Bolt technically unique is its foundation on WebContainers, StackBlitz's proprietary technology that runs a full Node.js runtime directly inside your browser tab. Unlike traditional cloud development environments that spin up remote virtual machines, WebContainers execute everything locally in your browser's WebAssembly sandbox. This means zero cold starts, no server costs, and near-instant feedback. When Bolt generates your application code, it installs npm packages, starts the dev server, and renders a live preview — all within the same browser tab, often in under ten seconds.

Bolt supports a broad range of modern web frameworks out of the box. You can prompt it to create a React dashboard, a Next.js marketing site, a Vue admin panel, a Svelte blog, or a plain Node.js API server. It handles the entire project setup — file structure, configuration files, dependency installation, and routing — so you skip the boilerplate entirely. Once the initial scaffold is generated, you can continue iterating by prompting Bolt to add features, fix bugs, or restyle components, or you can edit the code directly in the built-in editor.

Deployment is built into the workflow as well. Bolt offers one-click deployment to Netlify, letting you go from idea to live URL in minutes. For developers who prefer other hosting platforms, you can export your project to GitHub or download it as a ZIP and deploy anywhere — Vercel, Cloudflare Pages, Railway, or your own server. This combination of instant scaffolding, live preview, and frictionless deployment makes Bolt particularly popular for prototyping, hackathons, MVPs, and rapid iteration on client projects.

Key Features

Everything runs in your browser — no local Node.js installation, no terminal setup, no environment configuration. Open bolt.new, type a prompt, and start building. Works on any device with a modern browser, including Chromebooks and tablets.

⚡

WebContainers Technology

StackBlitz's WebContainers run a full Node.js runtime inside your browser using WebAssembly. No remote servers means zero cold starts, no network latency for file operations, and instant npm package installation. Your code never leaves your browser until you choose to deploy.

🔧

Multi-Framework Support

Build with React, Next.js, Vue, Nuxt, Svelte, SvelteKit, Astro, Remix, or plain Node.js. Bolt handles all the project configuration, bundler setup, and dependency management automatically. Switch frameworks between projects without installing anything new.

💬

Prompt-to-App

Describe your application in natural language and Bolt generates the complete project — files, components, routes, styles, and configuration. Continue refining with follow-up prompts like "add a dark mode toggle" or "connect this form to a Supabase database."

🚀

One-Click Deploy

Deploy your project to Netlify with a single click directly from the Bolt interface. No CI/CD pipeline setup required. You can also export to GitHub for deployment on Vercel, Cloudflare Pages, or any other hosting platform you prefer.

👁️

Real-Time Preview

See your application running live as you build it. Every code change — whether from an AI prompt or a manual edit — is reflected instantly in the embedded preview panel. Hot module replacement keeps the preview fast and responsive, even for complex applications.

How to Build an App with Bolt

Getting started with Bolt takes less than a minute. Navigate to bolt.new in any modern browser, sign in with your GitHub or Google account, and you are ready to build. There is nothing to install and no local environment to configure.

Step 1: Describe your app. Type a natural language prompt in the chat panel. Be as specific as possible — "Build a React dashboard with a sidebar navigation, a stats overview page with four KPI cards, and a settings page with a form for updating profile information" will produce better results than "Make me a dashboard." Bolt interprets your prompt, selects the appropriate framework, and generates the full project scaffolding.

Step 2: Preview and iterate. Within seconds, Bolt displays a live preview of your running application alongside the generated source code. You can edit files directly in the built-in code editor or send follow-up prompts — "Add a chart to the stats page using Recharts" or "Make the sidebar collapsible." Each change is reflected in the preview immediately.

Step 3: Deploy or export. When you are satisfied with the result, click the Deploy button to publish to Netlify instantly, or export the project to GitHub for further development in your preferred IDE. The generated code is clean, well-structured, and uses standard tooling — you can continue building locally in VS Code, Cursor, or any other editor without any lock-in.

What Can You Build with Bolt?

Bolt excels at a wide range of web application types. Here are some common use cases developers build with it daily:

SaaS MVPs and landing pages: Founders use Bolt to go from idea to working prototype in a single afternoon. Describe your product's core functionality, and Bolt generates the UI, routing, and basic logic. Add authentication with Supabase or Firebase through follow-up prompts, style the landing page, and deploy — all without opening a terminal.

Internal tools and dashboards: Teams build admin panels, data dashboards, and internal CRUD applications that connect to existing APIs. Bolt's ability to scaffold forms, tables, and chart components from a description makes it significantly faster than manual coding for these common patterns.

Portfolio sites and blogs: Developers and designers create personal websites using Astro, Next.js, or Svelte. Since Bolt handles all the configuration and build tooling automatically, you can focus entirely on content and design rather than fighting with bundler configs and deployment pipelines.

Alternatives to Bolt

If Bolt doesn't match your workflow, these four alternatives cover different approaches to AI-assisted development.

Lovable

Design-first AI app builder focused on non-technical users. More guided workflow with a visual editor. Great for MVPs when you want less code and more drag-and-drop.

v0 by Vercel

AI UI component generator that creates React components from text prompts. Ideal when you need individual UI pieces rather than full applications. Integrates natively with the Vercel ecosystem.

Cursor

AI-first desktop code editor built on VS Code. Better for developers who want full local control, codebase-aware chat, and multi-file refactoring in a traditional IDE environment.

Replit

Browser-based IDE with AI code generation and cloud compute. Supports more languages beyond JavaScript (Python, Go, Ruby) and offers always-on hosting for backend services.

Frequently Asked Questions

What is Bolt by StackBlitz?

Bolt (bolt.new) is an AI-powered full-stack development environment created by StackBlitz. It runs entirely in your browser using WebContainers technology, allowing you to build, preview, and deploy complete web applications from a simple text prompt — no local setup, no terminal commands, no package manager installation required. It supports React, Vue, Svelte, Next.js, Astro, and many other modern frameworks.

Is Bolt free to use?

Yes. Bolt offers a free tier with a limited number of AI tokens per day, which is enough to build small projects and experiment with the platform. The Pro plan at $20 per month provides significantly more tokens and faster generation speeds. The Team plan at $50 per user per month adds shared workspaces, collaboration features, and priority support for organizations.

How does Bolt compare to Lovable?

Both Bolt and Lovable let you build apps from text prompts, but they take different approaches. Bolt gives you a full development environment with a file tree, code editor, terminal access, and framework flexibility — it feels more like a browser-based IDE. Lovable focuses on a more guided, design-first workflow optimized for non-technical users building MVPs. Developers who want more control tend to prefer Bolt; those who want more hand-holding prefer Lovable.

What frameworks does Bolt support?

Bolt supports a wide range of modern web frameworks including React, Next.js, Vue, Nuxt, Svelte, SvelteKit, Astro, Remix, and plain Node.js backends. You can also use it for vanilla HTML/CSS/JavaScript projects. The WebContainers runtime supports npm packages natively, so most tools and libraries in the JavaScript ecosystem work out of the box without additional configuration.

Can I deploy apps built with Bolt?

Yes. Bolt includes one-click deployment to Netlify directly from the editor interface. You can also export your project as a ZIP file or push it to a GitHub repository for deployment on any hosting platform you prefer, including Vercel, Cloudflare Pages, Railway, or your own server. There is no lock-in — the generated code is standard and portable.

What are WebContainers?

WebContainers are a browser-based runtime developed by StackBlitz that executes Node.js directly inside your web browser using WebAssembly. Unlike traditional cloud development environments that require remote servers, WebContainers run entirely locally in your browser tab. This means zero cold starts, no server provisioning costs, no network latency for file operations, and near-instant npm installations. WebContainers are the core technology that makes Bolt's speed possible.

Is Bolt suitable for production applications?

Bolt is excellent for prototyping, MVPs, internal tools, and smaller production applications. For very large or complex production systems with extensive backend logic, microservices architectures, or databases beyond SQLite, you may eventually want to export the project and continue development in a traditional local environment. Most teams use Bolt to get started fast — building and validating the initial version — then migrate to a local setup as the project's complexity grows beyond what a browser environment comfortably handles.
