Design with auto layout, component variants, vector networks, design tokens, and interactive prototypes. Opens instantly, works 100% offline, guarantees memory safety, and keeps your intellectual property on your local machine.
A clean-room interface design suite engineered from the ground up without Electron bloat or cloud vendor lock-in.
Dynamic flexbox and auto layout algorithms matching production CSS. Hug contents, fill container, absolute positioning, nested padding, and flex wrap.
Build scalable design systems with reusable master components, variant matrices, slot overrides, and instance propagation that never loses overrides.
Modern non-linear vector paths. Draw branches, merge nodes, and perform clean Boolean pathfinder operations (Union, Subtract, Intersect, Exclude) with subpixel precision.
Multi-dimensional design tokens. Toggle between Light Mode and Dark Mode, compact and cozy density, or multi-brand palettes with a single click.
Fluid transitions, spring physics, click, hover, drag, and gamepad triggers. Test real interactive mobile and desktop flows before writing code.
Your work belongs to you. HypUI doesn't phone home, doesn't inspect your canvas, and stores files strictly on your local SSD in open formats.
Compare HypUI with legacy design software and experience the modern standard of speed and privacy.
