AI · San Francisco, United States · Founded 2017

StackBlitz is a browser-based development platform that allows users to build, run, and deploy full-stack web applications directly from their browser, without the need for local setup. Its core innovation, WebContainers, enables Node.js environments to run entirely in the browser using WebAssembly, offering instant boot times, offline support, and enhanced security. This makes it faster and more efficient than traditional cloud IDEs, with built-in support for popular frameworks like React, Vue, and Next.js. Bolt.new is StackBlitz’s AI-powered development tool, launched in October 2024. It combines advanced AI models with WebContainers to let users generate, edit, and deploy apps using natural language. The AI can control the full development environment—including the filesystem, terminal, and package manager—allowing it to handle an entire app lifecycle. With over 3 million users and $30M in annual recurring revenue within months of launch, Bolt.new became the second fastest-growing product in history after ChatGPT.
