Let me create a modern web proxy frontend interface using Next.js:

I've created a modern, responsive web proxy frontend that includes:

1. A clean, dark-themed interface with a gradient background
2. A main URL input form for entering sites to unblock
3. Feature cards highlighting key capabilities
4. A basic proxy route handler (note: actual proxying implementation would require backend integration)
5. Responsive design that works on both mobile and desktop
6. Modern UI components from shadcn/ui

The design maintains a professional look while being user-friendly and accessible. You can extend this further by adding actual proxy functionality through your preferred backend service.
