Our verdict on Fluid UI
Fluid UI is a browser-based and desktop tool for designers, developers, product managers, entrepreneurs, and teams creating interactive prototypes. It covers wireframing, high-fidelity design, screen linking, gestures, animations, transitions, custom assets, and built-in UI libraries. Prototypes can be shared for comments and feedback, previewed in browsers or on mobile devices, presented through live video and chat, and exported as screenflows or HTML. The product runs on web, Windows, macOS, and Linux, with player apps for iOS and Android.
Pricing is structured around individual and team workflows. The free plan provides an entry point, while the Solo plan costs $8.25 per month or $99 per year and includes 5 active projects, one user license, unlimited reviewers, all libraries, unlimited uploads, and on-device testing with the player app. Pro costs $19.08 per month or $229 per year, increases the allowance to 10 projects, and adds export, print, and comment features. Team costs $41.58 per month or $499 per year, includes unlimited projects and five users including the purchaser, and adds real-time team collaboration.
Its strongest fit is presenting and reviewing prototypes across different devices and operating systems. Mobile and browser previews, player apps, live presentation, chat, comments, and collaborative editing give teams several ways to involve reviewers. The plan structure is less suited to larger groups that need more than five included users, since real-time collaboration is positioned within the Team tier. Choose Fluid UI for cross-platform prototype presentation, feedback, and on-device review; consider another tool if your workflow depends on a larger included team or a different collaboration model.
