StackBlitz

StackBlitz offers an instant, browser‑based full‑stack development environment designed to feel as fast and capable as a local setup. Its core technology, WebContainers, allows a complete Node.js environment to run directly inside the browser, enabling exceptionally fast project startup times, seamless npm package installation, live previews, and secure sandboxed execution without relying on remote servers. The platform mirrors a VS Code‑like experience with an in‑browser editor, integrated terminal, and hot‑reloading workflow, making development smooth and responsive. It supports modern JavaScript frameworks such as React, Angular, Vue, and Next.js, allowing developers to build full-stack applications entirely online. StackBlitz also enables easy project sharing through link‑based environments that load instantly for collaborators. For teams and documentation creators, it provides interactive embeds, reproducible examples, and environments that stay online without sleeping. With its advanced WebContainer API and powerful AI‑driven companion tool, Bolt.new, StackBlitz delivers a fast, secure, and highly portable coding experience that simplifies development workflows from prototyping to production.
