Code Editor
The editor is the same Monaco engine that powers VS Code, with syntax highlighting, a minimap, code folding, and bracket matching. Pick from 18 languages (JavaScript, TypeScript, Python, Java, C#, C++, Go, Rust, SQL, HTML, CSS, JSON, and more) and a light, dark, or high-contrast theme.
Open a file from your device to edit it, then save your work back to a file - the File System Access API saves to your chosen file where the browser supports it, and downloads everywhere else. You can also save named snippets that persist in this browser so you can reload them later, no account required.
