Balsamiq Mockups 是一款Mac上强大和优秀的产品原型「草图」设计软件，新版本中增加了大量新的功能，和Axure相比，这款软件的定位在于产品设计的草图设计阶段，并非Axure的高精确的产品原型定位，所以，二者是可以配合使用的，笔者非常喜欢Balsamiq Mockups这款软件的草图组件，让人感觉非常的漂亮，除了Web设计，还支持iPhone移动应用的设计，强烈推荐！


Using Mockups feels like drawing, but because it is digital, you can adjust and rearrange. Teams can arrive at a design and iterate on it in real time during a meeting. Product managers, designers, developers and even customers can now work together in the same tool to quickly iterate over wireframes, before writing code.
Focus on content and functionality
Wireframes structures Low-Fi. Incomplete and low-fidelity wireframes let you focus design conversations on functionality.
Components and icons user interface. 75 integrated user interface components and 187 icons, plus a lot of components generated by the community.
Prototypes clickthrough. Linking lets you generate click-through prototypes for demos and usability testing.
Export to PNG or PDF. Share or present mockups with embedded by exporting PDF, or use a third party tool to export to code links.
Never waste a minute
