# MCP Apps: iFrame vs Native UI Integration

MCP apps can integrate via iFrame (sandboxed web views) or native UI components. iFrames offer isolation, native UI provides deeper integration and better UX.

## Detailed Comparison

| Factor | iFrame Embedding | Native UI Integration | Winner |
|--------|------|------|--------|
| UX |  |  | Native UI Integration |
| Security |  |  | iFrame Embedding |
| Dev Speed |  |  | iFrame Embedding |
| Performance |  |  | Native UI Integration |
| Customization |  |  | Native UI Integration |

## Key Statistics

- **200-500ms vs 50-100ms** (2026)
- **1-2 weeks vs 4-8 weeks** (2026)

## Choose iFrame Embedding when...

- Need tight integration with core features
- Focus on user experience
- Develop complex applications

## Choose Native UI Integration when...

- Need quick prototyping
- Work on add-ons and extensions
- Require flexibility in design

## Our Recommendation

Native UI is superior for core features. iFrame works well for add-ons and rapid prototyping.
