StackBlitz was founded by Eric Simons and Albert Pai in 2017 in San Francisco. The company has raised over $10 million in funding and made a significant breakthrough with its WebContainers technology.
WebContainers, released in 2021, run Node.js natively inside the browser using WebAssembly. This isn’t a remote server or a VM — it’s a full Node.js environment running on your machine through the browser. The result is near-instant startup times (under 2 seconds), offline capability, and zero server costs. It was a genuine technical achievement that changed what people thought was possible in a browser.
StackBlitz supports full-stack frameworks like Next.js, Nuxt, SvelteKit, and Astro. You can install npm packages, run dev servers, and use the terminal — all within the browser. Because everything runs locally, there’s no latency for file operations or server restarts.
Codeflow IDE, StackBlitz’s VS Code-based editor, brings the full VS Code experience to the browser with extension support. The GitHub integration lets you open any repository in StackBlitz with a single click by changing “github.com” to “stackblitz.com” in the URL.
StackBlitz is used in documentation for Angular, Vite, SolidJS, and other frameworks. The bug reproduction workflow is particularly popular — maintainers ask users to reproduce issues in StackBlitz instead of setting up local environments. The platform has over 12,000 GitHub stars and processes millions of development sessions. The team continues to push WebContainers forward, adding support for more Node.js APIs and better performance.
