What is StackBlitz WebContainers?

StackBlitz WebContainers provide a groundbreaking client-side runtime that runs Node.js, package managers, and full-stack frameworks directly inside the browser. They eliminate the need for remote development servers by using the user's local CPU and memory for compute, delivering unmatched performance, security, and scalability. Through the WebContainer API, developers can boot an isolated environment, mount project files, install dependencies, and execute dev scripts exactly as they would on a local machine. This capability enables highly interactive experiences like full-stack playgrounds, live documentation, onboarding workflows, educational sandboxes, and AI-native IDEs that operate entirely in-browser. WebContainers support all major frameworks, Wasm workloads, and modern browsers including Chromium, Firefox, and Safari Technology Preview. They provide native support for npm, pnpm, and yarn, enabling realistic, production-grade workflows in disposable environments. Because execution happens on-device, teams drastically reduce infrastructure costs while delivering fast, low-latency development experiences. The API is designed for reliability, making it easy to create branded, custom editors or integrate with existing apps. Leading companies and open-source maintainers rely on WebContainers for secure, interactive environments that accelerate shipping and improve developer experience. As the backbone of StackBlitz's own platform, WebContainers are continuously refined and production-proven, offering a future-ready foundation for web-based development tools.
