Bolt.new is an AI-powered full-stack web development platform by StackBlitz that enables users to build, run, edit, and deploy complete web applications directly in the browser using natural language prompts. It addresses the barrier to entry in web development by combining an AI coding assistant with an in-browser development environment powered by WebContainers technology, eliminating the need for local setup, package installation, or server configuration. Users can go from a text description to a fully functional deployed application in minutes without leaving their browser.
Bolt.new differentiates itself by running a complete Node.js environment inside the browser using WebContainers, meaning it can install npm packages, execute server-side code, run build tools, and manage databases all within a single browser tab. It supports major frameworks including Next.js, Astro, Remix, Vite, and more, and provides a full-featured code editor alongside the AI chat interface. The platform includes integrated deployment to Netlify, real-time preview of changes, version history for reverting edits, and the ability to attach images or design files as context for the AI to reference during generation.
Bolt.new targets developers, entrepreneurs, designers, and product managers who want to rapidly prototype or build production web applications without the overhead of traditional development environments. It is particularly popular for creating MVPs, landing pages, internal tools, and side projects where speed matters more than granular control. The platform integrates with GitHub for code export, supports Supabase for backend database needs, and provides shareable project links for collaboration and review.
