Bolt AI builder: Websites, apps & prototypes

Bolt.new is a browser-based AI-driven full-stack development tool built by StackBlitz, enabling developers to move from concept to deployment using natural language prompts without any software installation or environment setup. It integrates a code editor, AI assistant, cloud runtime, and one-click deployment, supporting instant construction of frontend, backend, and databases for websites, apps, and prototypes. Unlike traditional IDEs or cloud environments, Bolt.new leverages StackBlitz's proprietary WebContainers technology to run a complete Node.js environment directly in the browser, allowing compiling, building, and testing without a backend server. The AI assistant understands complex programming needs, automatically generates code, fixes errors, and provides real-time suggestions, even handling cross-component logic. Real-time multi-user collaboration enables teams to work on the same project without syncing environments. This tool excels for individual developers, startups, and product managers who need to quickly validate ideas by generating functional MVPs from simple descriptions. Educators and students can use it for interactive programming lessons without worrying about local environment differences. Hackathon teams and short-term projects benefit from drastically reduced time-to-completion, while experienced full-stack engineers can use it as an efficient scaffolding tool for fast prototyping before deep customization. Technically, Bolt.new's WebContainers are the industry's only solution for securely running full Node.js applications in the browser, a technology already trusted by GitHub, Microsoft, and millions of developers. Its free pricing lowers barriers for budget-constrained or exploratory projects. As AI-assisted programming grows, Bolt.new's zero-configuration, real-time collaboration, and end-to-end cloud-native experience are redefining full-stack development in the browser.
