Online Code Editor - Monaco Editor with Syntax Highlighting Free

A fast, full‑featured code editor in your browser

A modern, syntax‑highlighting code editor that opens instantly in your browser — no installs, no projects, no setup. Edit JavaScript, TypeScript, Python, HTML, CSS, JSON, Markdown and dozens of other languages with the same Monaco engine that powers VS Code.

Use it for quick scratch coding, snippet refinement, code reviews, drafting markdown documentation, or just having a powerful editor open in any browser when you're away from your main machine. Because everything stays in the browser, you can paste sensitive code, internal docs, or customer data without privacy worry.

The editor includes find/replace, multi‑cursor editing, automatic indentation, syntax‑aware suggestions and customizable themes, giving you a real coding workspace that runs anywhere — from a Chromebook in a coffee shop to a tablet on the road.
