Instant dev experiences

Wait, I can enjoy web dev again?

Significantly reduce time to market with matchlessly secure, instantly reproducible, fullstack dev environments which boot in milliseconds.

Instant Bug Reports

Create zero-overhead, live templates for your users to reliably submit bugs against, filtering out true issues from everything else.

Share complete environments with only a url, and never spin up heavy local installations for a simple bug report ever again.

Interactive Documentation

Use the StackBlitz SDK to embed and interact with actual code in your actual docs, blog or website.

Bleeding Edge

The first dev environment faster and more secure
than local.

Introducing WebContainers: Run Node.js in your browser Read The Release

Powered by WebContainers, the first WebAssembly-based operating system which boots entire development environments in milliseconds, securely within your browser tab.

What about other online IDEs?

Unlike StackBlitz, legacy online IDEs run on remote servers and stream the results back to your browser. This approach yields few security benefits and provides a worse experience than your local machine in nearly every way.

StackBlitz solves these problems by doing all compute inside your browser. This leverages decades of speed and security innovations and also unlocks key development & debugging benefits (see below).

Unleashing the power of your browser.

Seamless Node.js debugging with Chrome Dev Tools

Debug backend applications just as easily as frontend, using the powerful tools already shipped in your browser.

Debug Node.js code with Chrome DevTools

Run the backend in the frontend

If it can run on Node.js, it can run on StackBlitz WebContainers, including backend functionality and libraries, meaning you can run servers. In your browser.

Run API servers in your browsers

Fresh, fast environments on every page load.

Reinstalling node_modules is as simple as refreshing the page, and since StackBlitz package installations are orders of magnitude faster than local, installing packages is now a trivial endeavour.

Fresh environments on page load

Zero latency. Work offline.

No external servers to connect to means no delays between your keystrokes and editor, and an internet connection is not required.

Works offline

“It's surely only a matter of time before locally installed IDEs go the way of the Walkman.
