Everything you need to ship faster

Built for developers who want AI that actually understands their code — not just autocomplete.

Agentic AI Mode

The AI creates a task list first, then executes each step one by one — editing code in-place with SEARCH/REPLACE patches, just like a real developer would.

VS Code-like UI

Activity bar, file explorer, tabbed editor, live preview, command palette, and status bar — the full IDE experience in your browser.

Extension System

Install community extensions or build your own. Extensions can add panels, commands, themes, and language support. Full API docs included.

Theme System

Switch between built-in themes or create your own with the visual theme editor. Export and share themes as JSON or ZIP files.

Full File Management

Create, rename, duplicate, delete files and folders. Import/export ZIP archives. Drag and drop files directly into the editor.

Live Preview

Instant HTML/CSS/JS preview with hot reload. Open side-by-side or in a new tab. CSS and JS files are automatically inlined.
