Justinmind is a powerful free design and prototyping tool for creating high-fidelity prototypes and functional simulations of web and mobile applications without writing a single line of code. It helps designers and product teams validate ideas early, reduce rework, and boost user adoption by bringing interaction design to a superior level.
The platform’s main features focus on realistic simulation and comprehensive collaboration. Users can design the full range of product interactions, from basic web links to advanced sequences and conditions, and mobile gestures like tap, swipe, and pinch. It includes a Free UI Design tool with vector design capabilities for creating UI assets and supports the entire design cycle, from low-fidelity wireframes to high-fidelity simulations. Justinmind allows for the design and simulation of fully functional Forms and Data Lists interaction. For collaboration, it enables Team Prototyping where multiple users can work on the same prototype simultaneously with version control, and a simple one-click Share and Get Feedback feature for all stakeholders. It streamlines the development process with Design Handoff for Developers to inspect prototypes and retrieve UI assets, and the ability to export prototypes to fully functional, interactive HTML or to generate detailed Specification Documents with a single click.
