Designing an interface often involves more than arranging screens: teams may also need to prototype interactions, share work and prepare a handoff to developers. Compare interactive prototyping and prototype sharing with real-time collaboration, design systems and variables tokens. Desktop app availability can matter to how you work, while developer handoff, free plans and paid-from pricing add practical comparison points. Mockplus, UXPin and Fluid UI are among the tools shown, with Justinmind, Marvel and Proto.io also included. Think about how your process moves from early interface ideas to shared prototypes and development, then weigh the listed features against those needs.
