GUI Prototyping

4 Best Free and Open Source GUI Prototyping Tools

Whether it is by pure experimentation or transforming a vision into something tangible, prototypes help assist in testing and building while preserving overall design consistency.

Clients are notorious for not accurately defining their requirements, in part because they don’t necessarily know what they need, or what would work best. Even when a client accurately describe their requirements, this doesn’t necessarily percolate to the developers. Besides the usual process of meetings, emails and phone conversations, a visual design can make a real difference. Step forward prototyping tools.

Prototyping tools let designers and clients collaborate more efficiently. Clients experience a visual overview of what is actually going to be developed. It helps teams to build understanding, to explore options and barriers that only become visible when you build and test something. Ultimately, prototyping tools become a platform for full creativity and experimentation for the product team.
