🛠 The Platform Architecture

Unlayer isn't just one tool; it is a cohesive platform built on seven core primitives that can be composed to create any content surface your users require.

---

🎨 Specialized Builder Suite

Depending on your product's needs, you can deploy specific builders tailored for different outputs:

• Email Builder: Create responsive designs that look perfect across $\text{Gmail}$, $\text{Outlook}$, and $\text{Apple Mail}$.
• Page Builder: Enable users to construct landing pages and forms using breakpoints and flexible columns.
• Document Builder: Professional-grade tools for contracts and reports, complete with cover pages and PDF export.
• Popup Builder: High-conversion lead capture tools with customizable triggers and rules.

🤖 AI-Powered Content Workflows

Unlayer integrates AI directly into the block and document levels to keep users in their creative flow.

The AI Optimization Path:

• 01. Generate: "Create a 3-column features section for onboarding."
• 02. Rewrite: Tighten the prose, shift the tone, or translate the text.
• 03. Iterate: Create $N$ branded variations from a single master template.
• 04. Personalize: Inject merge fields and recipient-specific blocks.
• 05. Optimize: Let AI suggest better visual hierarchies for your blocks.

Example Command: ⌘ K $\rightarrow$ "Generate a hero block for a summer sale."

💻 The Developer Experience

Unlayer is built for engineers. It moves you from months of development to $\text{days of integration}$.

Technical Stack

1. Embeddable SDK: Full control over themes, events, and granular permissions.
2. React Elements: Write JSX once; render it as email tables, web flexbox, or print-ready PDFs.
3. JSON Designs: All designs are stored as JSON, making them versionable and easy to diff.
4. CLI & Agent Skills: Native support for Cursor, Claude Code, and Codex to automate your CI pipelines.

Implementation Example

// Initialize the Unlayer Editor
const builder = unlayer.createEditor({
  id: 'editor',
  displayMode: 'email',
  appearance: {
    theme: 'modern_light'
  }
});

// Export the design to HTML
builder.exportHtml(function(data) {
  const exportedHtml = data; 
  console.log("Design exported successfully!");
});
