Fluid UI serves as an interactive platform designed to facilitate the creation and evaluation of web and mobile user interface prototypes. Users can swiftly develop mockups for their ideas, simulating user flows, gestures, and interactions prior to commencing development. The intuitive drag-and-drop interface is equipped with numerous tools and libraries, making it straightforward to assemble wireframes from a vast selection of pre-built components. Real-time collaboration capabilities enable teams to provide immediate feedback regarding UI/UX, fostering timely refinements.

With access to 2,000 pre-existing components sourced from material design, iOS, Windows, and wireframe libraries, users can efficiently create prototypes. The platform supports the uploading of custom assets, along with the use of touch and mouse gestures. Features like interactive linking for user flows, animations, and live video collaboration further enhance the prototyping experience. Additionally, remote user testing capabilities allow prototypes to be assessed by users across various locations, providing crucial insights to enhance the final product. Fluid UI is accessible via web browsers, a desktop application, and mobile preview apps, ensuring flexibility for testing across different devices.
