Code Studio — Free Online Code Editor

Code Studio is a free online code editor that runs in your browser. Create a project, add as many files and folders as you need, and write code in languages such as HTML, CSS, JavaScript, TypeScript, Python, Java, C, C++, C#, PHP, Go, Rust, Ruby, SQL and more, with syntax highlighting for each.

How it works

• Live preview: HTML, CSS and JavaScript projects run in a sandboxed preview. Linked CSS, JS and image files from your project are picked up automatically, and links between your pages work.
• Console: console.log output and errors from your page appear in the built-in console.
• Other languages: Python can be run in the preview. Other languages are editable and are saved and downloaded with your project, but they are not executed.
• Download: One click packs the whole project, folders included, into a ZIP file.
• Your files stay with you: Projects are stored in this browser for your account. They are not uploaded to a server, so download a ZIP as a backup before clearing browser data.
