Features

Everything you need to
make code look stunning

200+ Languages

Syntax highlighting powered by Shiki with VS Code's TextMate grammars. JavaScript, Python, Rust, Go, and many more.

Self-Contained HTML

Exported HTML files work completely offline. All styles are inlined — zero external dependencies, ever.

Retina PNG Export

Export at 1x, 2x HD, or 4x 4K resolution. Crystal-clear output for presentations, docs, and social media.

macOS Window Chrome

Realistic traffic light dots, title bar, and rounded corners. Your code looks like it's running in a real terminal.

Glass & Solid Modes

Choose between frosted glassmorphism with backdrop blur or classic solid window backgrounds. Both look incredible.

Custom Backgrounds

Gradients, solid colors, wallpaper images, or build your own gradient. 25+ presets included out of the box.
