⚡ Built in Pure Rust by WebSpider Studios • Zero Telemetry

The Sovereign, High-Speed
Figma Alternative

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.

🛡️ 100% Safe Rust (#![forbid(unsafe_code)]) 📁 Open .hypui format ⚡ Native macOS, Windows & Linux
HypUI Web Studio — Live Interactive Workspace
Full Screen Studio ↗

Engineered for Creative Sovereignty

A clean-room interface design suite engineered from the ground up without Electron bloat or cloud vendor lock-in.

📐

True Auto Layout Engine

Dynamic flexbox and auto layout algorithms matching production CSS. Hug contents, fill container, absolute positioning, nested padding, and flex wrap.

🧩

Components & Variants

Build scalable design systems with reusable master components, variant matrices, slot overrides, and instance propagation that never loses overrides.

✒️

Vector Networks

Modern non-linear vector paths. Draw branches, merge nodes, and perform clean Boolean pathfinder operations (Union, Subtract, Intersect, Exclude) with subpixel precision.

🎨

Variables & Mode Switching

Multi-dimensional design tokens. Toggle between Light Mode and Dark Mode, compact and cozy density, or multi-brand palettes with a single click.

🚀

Smart Animate Prototyping

Fluid transitions, spring physics, click, hover, drag, and gamepad triggers. Test real interactive mobile and desktop flows before writing code.

🛡️

Zero-Telemetry Privacy

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.

Why Creators Switch to HypUI

Compare HypUI with legacy design software and experience the modern standard of speed and privacy.

Enterprise Security & Exploit Defense

HypUI is engineered under strict zero-trust standards to ensure it cannot be exploited by bad actors or malicious payloads:

• Zip Slip & Path Traversal Guard: Archive members are sanitized and validated against parent navigation attempts.
• Zip Bomb & Decompression Limits: Enforced member limits (512MB) preventing RAM exhaustion attacks.
• Sandboxed WASM Plugins: Plugins run in an isolated interpreter (`wasmi`) with zero raw OS syscall privileges.
• Local-Only Control Server: Binds exclusively to 127.0.0.1 with mandatory cryptographically-secured token validation.
