    <CardImage src={props.image.url} />
    <CardTitle>{props.title}</CardTitle>
    <CardPrice>${props.price}</CardPrice>
  </Card>
);

// Marketers edit within safe boundaries
ProductCard.schema = {
  fields: [
    { name: "title", type: "text", maxLength: 50 },
    { name: "price", type: "number", min: 0 },
    { name: "image", type: "image", required: true }

Migration from Builder.io to Blocksweb

Why Teams Migrate:

Reliability Issues:

"We were tired of the editor breaking down during important campaign launches. Blocksweb just works."

— Marketing Director

Performance Problems:

"Our page load times improved by 40% after switching from Builder.io to Blocksweb."

— Senior Developer

Setup Complexity:

"Setting up Builder.io took our team 3 days. Blocksweb was running in 30 minutes."

— Tech Lead

Migration Process:

typescript
// 1. Export Builder.io content
const builderContent = await exportBuilderContent({
  apiKey: process.env.BUILDER_API_KEY,
  exportAll: true
});

// 2. Convert to Blocksweb format
const blockswebContent = await convertContent(builderContent, {
  preserveLayout: true,
  optimizePerformance: true,
  validateTypes: true
});

// 3. Import and deploy
await deployToBlocksweb(blockswebContent);

Migration Timeline:

  • Day 1: Export existing content and components
  • Day 2: Set up Blocksweb project and import content
  • Day 3: Test and optimize performance
  • Day 4: Switch DNS and go live

Technical Architecture Comparison

Blocksweb: Modern, Performant Architecture

typescript
// Clean, TypeScript-first approach
interface ComponentProps {
  title: string;
  subtitle?: string;
  variant: 'primary' | 'secondary';
}

export const MyComponent: IBlockswebComponent<ComponentProps> = (props) => {
  // Full type safety, performance optimized
  return <section className={`component--${props.variant}`}>
    <h2>{props.title}</h2>
    {props.subtitle && <p>{props.subtitle}</p>}
  </section>;
};

// Automatic performance optimization
MyComponent.config = {
  performance: {
    lazyLoad: true,
    codesplit: true,
    preload: 'viewport'
  }
};

Builder.io: Complex, Performance-Variable

Based on developer feedback:

  • More complex component definition process
  • Performance optimization requires manual configuration
  • TypeScript support feels bolted-on
  • Less predictable rendering performance
"The Builder.io code structure felt overcomplicated and hard to debug. When we switched to Blocksweb, our component definitions became much cleaner and easier to maintain."
