HTML5 CSS3 ES6+ Tailwind React

A Complete Client-Side Web IDE for HTML, CSS, and JS.

We stripped away the bloat of traditional cloud editors. Write HTML, CSS, and JavaScript in a zero-latency frontend workspace that responds at the speed of your thoughts.

Instant HTML, CSS & JS Preview

The local execution engine watches your keystrokes and injects frontend code updates instantly without ever reloading the browser IDE iframe.

import { hot } from 'nitro-ide';

hot.accept('./style.css', () => {
  console.log('Styles injected without reload!');
});

React & CDN Playground

Fetch any library from unpkg directly through the UI or CLI. Prototype React applications or Tailwind with zero setup.

> install tailwind
⚡ Success: Injected tailwind.

> install react

JavaScript State Visualizer

Debug complex JavaScript objects in real-time. Bind variables to our global hook and watch them update in the online workspace.

// Watch any variable
Nitro.watch(
  'User Data', userObj
);

Export Code to ZIP

Download your entire frontend workspace as a production-ready ZIP or bundled HTML file directly to your local machine.

const zip = new JSZip();
zip.file("index.html", code);
zip.file("style.css", css);
zip.generateAsync();

100% Local Execution

Your frontend code never leaves your local machine. No telemetry, no tracking, just a secure client-side sandbox.

// Local Execution Sandbox
const frame = document.createElement('iframe');
frame.sandbox = 'allow-scripts';
frame.srcdoc = compiledCode;
Command & Control

The Native JavaScript Console.

Stop relying on basic alert() popups. We built a fully featured developer console directly into the IDE with native CLI commands.

  • Native Object Serialization: Inspect deeply nested JSON arrays exactly like Chrome DevTools.
  • Syntax Highlighted Errors: Click any error to instantly jump to that exact line in the editor.
  • Integrated CLI: Type install gsap, export zip, or format directly into the console to control the workspace.
Terminal
// Interactive CLI Session
> install tailwind
⚡ Success: Fetched tailwind from unpkg.
> export zip

Aesthetic Engineering

An Offline-Ready Monaco Editor Sandbox.

A clutter-free, edge-to-edge workspace that respects your screen real estate. Because a beautiful environment writes beautiful code.

  • Monaco Editor Engine: Powered by the exact same text-editing core as VS Code with Emmet support.
  • Device Emulation: Instantly toggle your live preview between Desktop, Tablet, and Mobile breakpoints.
  • Virtual File System: Manage multiple `.js` and `.css` modules in a clean, draggable slide-out sidebar.

.workspace {
backdrop-filter: blur(24px);
border: 1px solid rgba(255,255,255,0.1);
box-shadow: 0 30px 60px rgba(0,0,0,0.5);
}

Enterprise Grade. Zero Cost.

Other cloud web IDEs charge you monthly just to keep your frontend projects private. We built a free, local code editor for the community.
