ZGUTT is a free, browser-based visual builder for WordPress Gutenberg block themes. You design your theme — colors, typography, spacing, templates — then export a complete, ready-to-install .zip block theme.

Yes. ZGUTT is 100% free to use. There is no account, no subscription, no upload. Your design stays in your browser and you keep the exported theme forever.

Do I need a WordPress plugin to use the exported theme?

No. ZGUTT exports a standard WordPress Block Theme (theme.json v3) that installs natively in WordPress 6.7+ via Appearance → Themes → Add New. No plugin required.

Does ZGUTT upload my work to a server?

No. ZGUTT is a local-first PWA. All design work happens in your browser. The .zip is generated client-side and downloaded directly to your device.

Which WordPress version does ZGUTT support?

ZGUTT generates Block Themes targeting WordPress 6.7 and later, using theme.json schema v3 and Full Site Editing (FSE).
