Today I wanted to share with you a quality collection of both free and paid UI kits. User interface kits can be incredibly handy should you wish to quickly build prototypes or design mockups. These user interface kits should help reduce your time spent working in photoshop and allow you to provide more work in a shorter time frame on a smaller budget.

Free UI Kits

These user interface kits are free to download and use, I have included a mix of different styles and kit types. I find the flat UI kits espressially refreshing to see, they look clean and elegant.
