30+ Free Photoshop PSD UI Kits

In the recent Web Design trend, the use of flashy illustrations, extraneous textures and drop down shadows are very minimal if not totally avoided. This is due to the growing influence of flat design – a user centric web design style.
UI kits are great packages for starters as they can save you lot of time. These kits usually come in PSD file formats and include brushes, patterns and a lot of user interface elements.
Flat UI contains many basic and complex components which are great & handy for designers like buttons, inputs, button groups, selects, checkboxes and radio-buttons, tags, menus, progress bars and sliders, navigation elements and more. All these can be easily modified and used in a wide variety of projects, as they contain original layers.
Hence, I have compiled some 30+ FREE downloadable Flat UI kits to help you create your next mockup quickly and efficiently.
