Wireframing Software
Alternatives to Fluid UI
Fluid UI is aimed at turning mobile-app ideas into shareable, interactive mockups. Its web-based workspace combines more than 2,000 components from Material Design, iOS, Windows and wireframe libraries with taps, swipes, clicks and page effects. Teams can work together in real time, save projects in the cloud, invite review through click-throughs, chat, annotations and comments, and run remote user-testing sessions. Browser access, a desktop client and Android and iOS preview apps support different presentation setups.

Choosing instead of Fluid UI
An alternative may make more sense when your workflow needs developer handoff, deeper logic, website planning or presentation slides. Fluid UI has a free plan, paid plans from $8.25/month, and support for Android, iOS, Linux, macOS, web and Windows. Compare each option's interaction model, collaboration and review tools, exports or integrations, device coverage and pricing. Also consider whether you need app-focused prototyping or a broader design workspace, and whether the alternative gives up capabilities Fluid UI provides.
