WordPress Theme Generation Tool
Overview
WordPress FSE Site Wizard is a developer tool that generates production-ready WordPress Full Site Editing themes from configurable templates. Rather than starting each FSE theme from scratch, this tool automates the scaffolding process — producing complete theme structures with block patterns, template hierarchies, theme.json configurations, and design system integration ready to customize.
WordPress Full Site Editing represents a significant shift in how themes are built, but the learning curve is steep and the boilerplate required for a well-structured FSE theme is substantial. This wizard dramatically reduces the time from concept to working theme by handling the repetitive structural work automatically.
Key Features
- Theme Scaffolding — Generates complete FSE theme directory structures with all required files and configurations
- Block Pattern Library — Pre-built, configurable block patterns for common page sections like heroes, feature grids, CTAs, and testimonials
- Design Token System — Generates theme.json with a complete design token configuration including colors, typography, spacing, and custom properties
- Template Hierarchy — Creates a full set of block templates covering front pages, archives, single posts, 404 pages, and custom post types
- Configurable Output — Options for typography stacks, color schemes, layout widths, and component styles before generation
- Best Practices Built In — Generated themes follow WordPress coding standards, accessibility guidelines, and FSE best practices
Technical Implementation
The wizard is built in PHP and operates as a command-line tool or web interface. It uses a template engine to compose block markup from modular components, ensuring that generated patterns are valid, well-structured, and compatible with the WordPress block editor.
The theme.json generation system understands the full specification of the WordPress design token format, producing configurations that properly cascade through the block editor’s style engine. This includes color palette definitions, typography presets with fluid sizing, spacing scales, and custom CSS properties that components can reference.
Block patterns are generated from a library of composable sections. Each section is parameterized — accepting color schemes, content placeholders, and layout options — so the same structural pattern can produce visually distinct results depending on the configuration inputs.
Why This Tool Exists
Building a WordPress FSE theme from scratch requires deep knowledge of the block editor internals, theme.json specification, and block markup syntax. Even experienced WordPress developers find the initial setup time-consuming and error-prone. This wizard encapsulates that knowledge into an automated process, letting developers focus on customization and design rather than boilerplate — turning what used to be days of setup into minutes.
