Wireframe tools are software applications that help designers create visual representations of a website or application layout. These tools allow users to sketch out the structure and functionality of a project without focusing on detailed design elements. Common features include drag-and-drop components, templates, and collaboration options, making it easier for teams to communicate ideas. Popular wireframe tools include Balsamiq, Axure, and Figma. Each tool offers unique features tailored to different design needs, such as interactive prototypes or user testing capabilities. By using wireframe tools, designers can streamline the development process and ensure a clear vision before moving to the final design stage.
