Key Highlights
Full Node.js Environment in Browser
WebContainer technology runs a complete Node.js runtime in the browser without local setup. Dependencies are installed instantly.
Real-Time Preview
Watch your application being built live as the AI writes code. Changes are reflected instantly in the preview and you can test interactively.
Broad Framework Support
React, Next.js, Vue, Svelte, Astro, Angular, and more. AI can select the most suitable framework based on project requirements.
One-Click Deployment
Publish your application with one click via Netlify integration. SSL, CDN, and continuous deployment are configured automatically.
About
Bolt.new by StackBlitz represents a paradigm shift in how web applications are built, combining three powerful technologies — AI code generation, browser-based development environments, and instant deployment — into a seamless workflow that eliminates most of the friction traditionally associated with software development. The platform's WebContainer technology runs a complete Node.js runtime in the browser, which means that when the AI generates code, it can immediately install dependencies, run build processes, and serve the application for preview, all without leaving the browser tab.
The development workflow begins with a natural language prompt. Users can be as general or specific as they want — from 'build a todo app with user accounts' to detailed specifications including technology choices, design requirements, and feature lists. Bolt.new's AI generates a complete project structure including source code, configuration files, package.json with appropriate dependencies, and environment setup. The generated code follows modern web development practices and supports a broad range of frameworks: React, Next.js, Vue.js, Nuxt, Svelte, SvelteKit, Astro, Remix, Angular, Express, Fastify, and more. The AI makes intelligent framework selection based on the prompt context when no specific framework is mentioned.
The real-time preview capability is central to the Bolt.new experience. As the AI writes code, users see the application building in real-time in a split-pane view — code on one side, live preview on the other. This immediate feedback loop transforms the development experience from a write-compile-test cycle into a conversational flow where changes are visible instantly. Users can interact with the preview — clicking buttons, submitting forms, navigating between pages — to verify that the generated application works as expected. If something isn't right, they can describe the issue in natural language and the AI will fix it, with the changes reflected immediately in the preview.
Iterative development is where Bolt.new truly shines. After the initial generation, users continue building through conversational prompts. The AI maintains full context of the project, understanding the existing code structure, installed dependencies, and implemented features. Requests like 'add a dark mode toggle,' 'create an API endpoint for user preferences,' or 'fix the mobile navigation layout' are processed with awareness of the entire codebase. The AI can modify multiple files simultaneously, install new packages, update configurations, and resolve dependencies as needed.
Deployment is handled through built-in Netlify integration, providing one-click publishing with automatic SSL, CDN distribution, and continuous deployment capability. Projects can also be downloaded as complete source code for local development or deployment to other platforms. The platform offers a free tier with daily token limits for AI interactions, while the Pro plan at $20 per month provides increased limits and priority access. The Teams plan at $50 per seat per month adds collaboration features and shared project management. Bolt.new has rapidly become one of the most popular AI development tools, particularly valued for its zero-setup approach and the ability to go from idea to deployed application entirely within a browser session.
