Bolt.new is an AI-powered full-stack web application builder by StackBlitz that runs a complete Node.js environment directly in the browser using WebContainers technology. Unlike most AI builders that hide the generated code, Bolt gives developers full visibility and editability of every file — enabling installation of any npm package, use of any framework (React, Vue, Svelte, Astro), and deployment to any infrastructure. It's the preferred AI builder for developers who want AI-accelerated productivity without sacrificing code ownership or framework flexibility. Bolt-generated apps follow standard web development patterns and deploy instantly via one-click integrations with Netlify. Pricing starts with a free tier and scales to Pro from $20/month for heavier usage.
