CODE
WITHOUT LIMITS

A Monaco-powered editor and live playground — built for the browser, works offline, runs everywhere.

SCROLL

Under the hood

Built different.
By design.

— 01

Monaco Engine

The exact same editor engine that powers VS Code. Syntax highlighting, IntelliSense, multi-cursor, bracket matching — all included.

— 02

Offline PWA

Install as a Progressive Web App. Service worker caches everything — editor runs fully offline after first load. No internet needed.

— 03

Real Files

File System Access API lets you open actual folders from your device, read and write directly — no upload/download dance.

— 04

Live Preview

Playground renders HTML in a sandboxed iframe in real time. Console messages are forwarded, errors are captured and displayed.

— 05

Python In Browser

Pyodide brings CPython to WebAssembly. Run real Python code — stdout and stderr captured and shown in the console panel.

— 06

Zero Backend

Pure static files. No server, no database, no login. Deploy to any static host — GitHub Pages, Netlify, your own server. Just works.

Open Source

Pure HTML.
No build step.
