Show HN: React and NextJS Interactions with MCP for AI Coding – Hyperiux Vault

Hyperiux Vault launched as a source-first interaction effects library for React and Next.js, installing scroll systems, cursor effects, text reveals, page transitions, loaders, backgrounds and WebGL scenes as editable files inside a project rather than as a runtime dependency. The Hyperiux CLI adds only the requested effect and the files it needs, and the library is built on React, Next.js, GSAP, Three.js, WebGL, Lenis and Motion, with usage rights following a Free Core or Pro license attached to each effect. Hyperiux positions Vault against animation primitives by shipping composed interaction patterns with timing, reduced-motion handling, mobile fallbacks and cleanup on unmount already in place.

Every moment, already built. Scroll systems, cursor presence, text reveals, transitions, loaders and WebGL scenes. Preview exactly how each one behaves before it touches your project. Source-first scroll systems, cursor effects, text reveals, page transitions, loaders, backgrounds, and WebGL scenes for React and Next.js. Installed as real files in your project, not a dependency you rent. Built on the tools your team already trusts React, Next.js, GSAP, Three.js, WebGL, Lenis and Motion. Production-grade motion, without the production complexity. amazing project app/page.jsx amazing project / Components ui The Hyperiux CLI adds only the effect you asked for and only the files it needs. No runtime dependency on us, no lock-in. Inspect it, change it, keep it. Tune it until it feels right. Copy, layout, timing, easing, breakpoints, hover states, mobile fallbacks and reduced-motion behaviour are all yours to tune. Try it: drag the sliders. Anyone can add a fade. What's hard is everything around it. Get timing, restraint, or performance wrong, and the moment meant to impress becomes the reason the site feels worse. Most teams see that risk and drop their ambitions to play it safe. And your interface ends up looking like everyone else's. Vault is engineered around that discipline by default, not as an afterthought. The Risks What Vault Fixes Dropped Frames Precise timing and sequencing tuned against actual hardware. Timing Motion Noise Motion that supports content, not distracts from it. Restraint Device Motion Off Respects user preferences and accessibility out of the box. Reduced-motion Jank & Layout Shift No unexplained CLS, no jank, no dropped frames as standard. Performance budget Hidden Bundle Size Dependency-honest. Every effect pulls in only what's needed. Dependency clarity Touch Devices Responsive behavior built for touch and smaller screens. Mobile fallbacks Memory Leaks No leaks, no ghosts, no lingering listeners. Cleanup on unmount Vertical scroll turned into a panoramic gallery track. A pinned slider with 3D card rotation and caption reveals. A pinned gallery with clip-path reveals and image parallax. Image strips that drift at alternating speeds as you scroll. Your credits are worth more than the plan. Vault is a source-first interaction effects library for React and Next.js. It covers scroll effects, text animations, cursor systems, page transitions, WebGL scenes, backgrounds, navigations, creative components. Effects install as editable code inside your project. Keep the UI library. Your design system handles interface primitives such as buttons, forms, cards, grids, and tabs. Vault handles how parts of the interface enter, respond, transition, and move through time. Those tools give you animation and rendering primitives. Vault gives you composed interaction patterns with a working structure, production decisions, and implementation guidance already in place. You still have the source, so the underlying tools remain fully available. The effect source is installed inside your project and can be inspected and modified locally. Usage rights follow the Free Core or Pro license attached to the effect. Any interaction can hurt performance when used badly. A text reveal and a continuous WebGL scene have very different costs. Vault exposes dependencies and implementation notes so your team can make that decision with the page, device, and performance budget in mind. Test production pages on real devices before shipping. Effects with significant motion should include a reduced-motion strategy or implementation guidance. The final behaviour remains under your control because the source lives in your project.
