Interactive wireframes that you can preview and test

Preview and test your prototypes and validate the complete experience in any browser, or as if viewed on a real device. You'll see how your real app or website will look in seconds, without coding.

UI Kits to create wireframes for iOS, Android and Web

Speed up your design process with ready-made and frequently updated UI libraries to wireframe web and mobile apps.
You can use all the interactive UI elements for web and mobile that are pre-loaded in Justinmind. Through easy drag & drop you can add them to the work area and create real and clickable prototypes in minutes, learning to appreciate the immediacy of Justinmind.

Clickable images in your web and mobile mockups

Wireframe many pages of a website or an app and build links between them, simply dragging the component to the screen you want to link to.
Add images to your wireframes and quickly create clickable regions with the hotspot tool. Prototypes made with Justinmind are more than just bare page changing: you will have a first version of your website or mobile app to show your users or clients.

A drag & drop wireframe design software

Find an efficient wireframe software in Justinmind! All images inserted into your wireframe can be modified to fit the dimensions and style of your design. Use guides, rulers, and the grid tool to place and align elements on the canvas.
You can also customize all your UI elements, by adjusting the edges of your borders, from sharp to completely round edges.

Styles and Fonts

All new projects start with a default template and Justinmind UI elements are contained within it.
You can change the default style, position, size, background, and layout distribution of any UI element to fit the look and feel of your screens.
A font type drop-down contains the list of fonts available on your system and an option to add more from Google fonts directory.

Integration with design tools

Linking images and SVG files can be especially helpful when working simultaneously with Photoshop, Illustrator or Sketch. All images embedded in your wireframe will be automatically updated whenever files are modified.
Furthermore, with Justinmind you can import, embed or link any SVG and other Vector files. You can also change their color, and scale them without losing quality.
