Greenlight Builder

The FSE Revolution: When WordPress Gets It Right

As a Growth Engineer who’s built hundreds of WordPress sites, I’ve watched the platform evolve from simple blogging to complex page builders. But here’s what most developers miss: Full Site Editing (FSE) isn’t just another feature—it’s WordPress returning to its roots while embracing the future.

Greenlight Builder understands this fundamental shift. While Blocksy perfects the traditional WordPress experience for WooCommerce and complex sites, Greenlight pioneers what FSE can be when you throw away legacy assumptions and build for tomorrow.

The Right Tool for the Right Job

Choose Greenlight when: Building content-driven sites, portfolios, landing pages, or any project where FSE’s simplicity outweighs WooCommerce complexity.

Choose Blocksy when: Creating comprehensive WooCommerce stores, membership sites, or projects requiring extensive third-party plugin integration.

The Single Block Philosophy: Less Is Exponentially More

Here’s what makes Greenlight revolutionary: One Elements block replaces the chaos of 50+ specialized blocks. This isn’t limitation—it’s liberation.

Traditional Block Approach Problems:

• Block Sprawl: 30-50 specialized blocks cluttering your editor
• Inconsistent APIs: Each block with its own settings paradigm
• Maintenance Nightmare: Updates breaking across dozens of components
• Performance Penalty: Every block adds weight and complexity
• Learning Curve: Mastering dozens of different interfaces

Greenlight’s Elements Solution:

/* One block, infinite possibilities through CSS variables */
.gl-element {
  --spacing: var(--gl-space-4);
  --color: var(--gl-primary);
  --animation: var(--gl-fade-in);
}

This single-block architecture means:

• Consistent Interface: Master one block, build anything
• CSS-First Control: Real CSS, not abstracted settings panels
• Global Coherence: Changes cascade predictably
• Performance Win: Minimal JavaScript, modern CSS
• True Composability: Combine classes, not blocks

Performance That Changes Business Metrics

Let me share real numbers from client projects after switching to Greenlight:

Core Web Vitals

• LCP: Under 1.2s (mobile)
• FID: Under 50ms consistently
• CLS: Near-zero layout shift
• TTI: 2.3s average on 3G

Business Impact

• 40% faster page loads vs traditional builders
• 23% better mobile engagement rates
• 18% reduction in bounce rates
• 2x faster development time

This isn’t theoretical—it’s what happens when you eliminate:

• Redundant JavaScript from multiple blocks
• CSS bloat from unused styles
• Runtime calculations for block rendering
• External dependencies and libraries

The FSE Advantage: Why Simpler Sites Need Modern Architecture

Perfect FSE Use Cases:

• Blogs & Publications: Direct template control
• Portfolio Sites: Visual-first editing
• Landing Pages: Rapid iteration without code
• Documentation: Structured content management
• Corporate Sites: Consistent brand application

FSE shines when your primary goal is content presentation, not complex functionality.

When to Avoid FSE - Use Traditional Themes For:

• Complex WooCommerce: Multi-vendor, subscriptions
• Membership Sites: Gated content, user dashboards
• LMS Platforms: Course management systems
• Community Sites: Forums, social features
• Legacy Projects: Existing plugin dependencies

These scenarios benefit from Blocksy’s comprehensive approach over FSE simplicity.

Developer Freedom: The Technical Deep Dive

Class-First Architecture

Greenlight’s approach treats WordPress like a modern development platform:

<!-- Traditional Block Approach -->
<div class="wp-block-buttons">
  <div class="wp-block-button is-style-fill">
    <a class="wp-block-button__link has-background">
      Click Me
    </a>
  </div>
</div>

<!-- Greenlight Approach -->
<div class="gl-element" data-style="button-primary">
  <a href="#">Click Me</a>
</div>

The difference? Control, performance, and maintainability.

CSS Variables System

Every aspect connects to a coherent design system:

:root {
  /* Typography Scale */
  --gl-text-xs: clamp(0.75rem, 0.7rem + 0.25vw, 0.875rem);
  --gl-text-base: clamp(1rem, 0.95rem + 0.25vw, 1.125rem);

  /* Spacing System */
  --gl-space-1: 0.25rem;
  --gl-space-2: calc(var(--gl-space-1) * 2);

  /* Animation Tokens */
  --gl-duration-fast: 150ms;
  --gl-ease-out: cubic-bezier(0.33, 1, 0.68, 1);
}

Dynamic Data Binding

Connect to any data source without custom development:

// Greenlight's proxy API approach
{
  source: "custom_field",
  field: "product_price",
  format: "currency",
  fallback: "Contact for pricing"
}

This beats traditional approaches that require:

• Custom PHP functions
• Plugin dependencies
• Manual ACF integration
• Complex query modifications

The Figma-to-WordPress Pipeline

Here’s what changes the game for agencies:

1. Design in Figma with components and variables
2. Export design tokens directly as CSS variables
3. Import to Greenlight maintaining complete fidelity
4. Build with Elements using your design system
5. Maintain consistency across all projects

No translation layer. No approximation. Your design system IS your WordPress theme.

AI Integration Without Privacy Concerns

Greenlight’s AI helpers connect directly to APIs—no middleware, no data collection:

• Content Generation: Direct OpenAI/Anthropic integration
• Image Creation: DALL-E/Midjourney API connections
• Code Suggestions: GitHub Copilot compatibility
• SEO Optimization: Direct API calls to analysis tools

Your API keys. Your data. Your control.

When Greenlight Beats Everything Else

”What about my existing sites?”

Keep them on Blocksy or current setup. Greenlight is for new projects embracing FSE. Don’t migrate—evolve forward.

”Is FSE production-ready?”

With WordPress 6.0+, absolutely. Major hosts optimize for it. The ecosystem has matured. Early adopters are already winning.

”What about WooCommerce?”

For simple stores, Greenlight’s WooCommerce FSE pack works brilliantly. For complex e-commerce, stick with Blocksy.
