Bolt.new is an AI-powered web development platform created by StackBlitz that enables users to build, run, and deploy full-stack web applications directly in the browser through natural language prompts. Launched in October 2024, it combines multiple AI models with StackBlitz's WebContainers technology to provide a complete in-browser development environment. Bolt.new reached approximately $40M ARR within its first six months.¹⁾

• Pricing: From $20/month
• Technology: WebContainers (in-browser Node.js)

Bolt.new is powered by StackBlitz's WebContainers technology, which runs a full Node.js environment, npm, and development servers entirely in the browser. This eliminates local setup requirements and enables:²⁾

• Instant code execution and live previews
• Full npm package installation
• Framework flexibility (React, Next.js, Vue, Svelte, Astro)
• No downloads or local installations required

Users describe applications in natural language through a chat interface. The AI generates editable code with real-time previews and handles iterative refinements. Supported AI models include:

• Claude (Anthropic) - primary model for code generation
• GPT-4o (OpenAI)
• Gemini (Google)

The AI automates testing, refactoring (reducing errors by 98% in benchmarks), and SEO optimization. Users maintain full code ownership and can export to GitHub at any time.
