The GUI Mockup design tool for Windows, Web and Mobile Applications
The best gui Mockup product for Desktop, Web and Mobile Applications
Easy to learn and to use. Very powerful for online prototyping. Solid reusable components and styling. great support and lively community. Possibility for annotations. Weak points - not optimized for printed specification, very slow in collaboration mode
This product is the best - comparing with many others (online and offline). After months of evaluation we choose and buy WireframeSketcher for our team (10 developers).
Web-based, fast, intuitive and fully interactive.
Current version 6 could be faster and with more search tools (i.e. to find a page to link)
