Key Features

• 4 panels — HTML, CSS, JS and TypeScript, each with line numbers and status bar.
• TypeScript transpilation — compiled client-side via the official TypeScript compiler. Errors shown inline.
• Auto-run — preview updates as you type (550ms debounce), or run manually with Ctrl+Enter.
• 8 built-in examples — Hello World, Glassmorphism, CSS Animation, Counter, Fetch API, TypeScript, Grid Layout, Canvas Particles.
• Layouts — side-by-side, top/bottom, editor-only, preview-only. Drag the divider to resize.
• Share via URL — your code is encoded into the URL hash so you can share any snippet as a link.
• JS error overlay — runtime errors appear as a banner inside the preview iframe.
