### Platform Selection

| Platform | Hosting | Custom Code | AI Support | Pricing | Best For |
|----------|---------|-------------|------------|---------|----------|
| n8n | Self-hosted/Cloud | ✅ Full | ✅ AI nodes | Free (self) | Developers, privacy |
| Zapier | Cloud only | Limited | ✅ AI actions | $29+/mo | Non-technical teams |
| Make | Cloud only | ✅ Modules | ✅ AI modules | $10+/mo | Visual workflows |

**Recommendation:** Use **n8n** for developer teams needing full control and self-hosting. Use **Zapier** for simple integrations by non-technical users.

### n8n Core Patterns

```typescript
// Custom n8n node — AI Content Processor
import { IExecuteFunctions, INodeExecutionData, INodeType, INodeTypeDescription } from 'n8n-workflow';

export class AiContentProcessor implements INodeType {
  description: INodeTypeDescription = {
    displayName: 'AI Content Processor',
    name: 'aiContentProcessor',
    group: ['transform'],
    version: 1,
    inputs: ['main'],
    outputs: ['main'],
    properties: [
      { displayName: 'Prompt Template', name: 'prompt', type: 'string', default: '' },
      { displayName: 'Model', name: 'model', type: 'options', options: [
        { name: 'GPT-4o', value: 'gpt-4o' },
        { name: 'Claude 4 Sonnet', value: 'claude-4-sonnet' },
      ], default: 'gpt-4o' },
    ],
  };

  async execute(this: IExecuteFunctions): Promise<INodeExecutionData[][]> {
    const items = this.getInputData();
    const prompt = this.getNodeParameter('prompt', 0) as string;
    // Process each item with AI...
    return [items];
  }
}
```
