About This Tool
Conceptually, interfaces are modeled as screens composed of blocks and controls. Prototyping links screens into flows, while a versioned component library maintains consistency across projects. Exports deliver design specs, assets, and handoff data suitable for developers.
Who benefits: product designers, UX researchers, frontend engineers, product managers, and startup teams seeking rapid ideation and iterative validation. Use cases include quick stakeholder reviews, multi-platform exploration, and maintaining a single source of truth for UI decisions.
Unique value: browser-based access requires no installation, with live collaboration, change history, and structured handoff artifacts. By centralizing designs and tokens, it reduces back-and-forth and accelerates delivery cycles while preserving clarity and consistency.
How to Use
- Create a new project and set target platform and initial canvas size.
- Add screens and drag-and-drop UI blocks to compose interfaces.
- Build a component library and link screens to define flows.
- Invite teammates for collaboration and iterate based on feedback.
