Code Editor

Code Editor puts VS Code’s editor in a browser tab. Open a folder from your disk and edit it with the same shortcuts, multi-cursor, minimap and TypeScript-aware autocomplete; Ctrl+S writes straight back to the file. No install, no account, and your files never leave your computer.

Features

Monaco, the editor inside VS Code: same keyboard shortcuts, command palette (F1), multi-cursor, minimap, folding and sticky scroll
Open a folder and save back to it (Chrome and Edge), or open a .zip, or keep a project in the browser
TypeScript and JavaScript autocomplete, hover types, go to definition, find references and rename across the whole project
Ctrl+P to jump to any file (name:line works), Ctrl+Shift+F to search and replace in all files with regex, case and whole-word options
File explorer with new, rename and delete; tabs with unsaved marks; split the editor in two
Syntax highlighting for about 80 languages, plus JSON, CSS and HTML validation
Live preview of web projects (HTML/CSS/JS, React, TypeScript, npm packages) in a sandboxed frame, with a console and phone/tablet widths
Templates: HTML/CSS/JS, React + TypeScript, a Node script
A terminal with ls, grep, pipes and redirects, npm install from the npm registry, and node to run your scripts (TypeScript too) in a sandbox
Settings for font size, tabs, word wrap, minimap and ligatures
Works offline after the first visit; download any project as a .zip

How to use it

Click Open folder and pick your project (or open a .zip, or try the sample).
Edit with autocomplete; Ctrl+P jumps between files and Ctrl+Shift+F searches them all.
Press Ctrl+S to save the file back to your disk.

FAQ

Are my files uploaded?

No. The editor runs entirely in your browser. A folder you open is read and written on your own disk; other projects are kept in this browser’s storage.

Which browsers can save to my disk?

Chrome and Edge (and other Chromium browsers) can open a folder and save to it. Elsewhere a folder opens as a copy kept in the browser, and you download your changes as a .zip.

Is this the real VS Code?

It uses Monaco, the editor at the heart of VS Code, so editing feels the same. It has its own terminal; VS Code’s extensions and debugger aren’t part of it.

Can I run npm install and node?

Yes, in the terminal (Ctrl+`). npm install downloads real packages from the npm registry and keeps them in your browser, and node runs your JavaScript or TypeScript in a sandbox. It isn’t a full Node.js: there’s no network, servers or native modules, so dev servers like Vite don’t run.

Does autocomplete understand my imports?

Yes: types flow across the project’s TypeScript and JavaScript files, and packages you npm install bring their types too.
