# About NudaUI > Who builds NudaUI, why it exists, how it is funded, and what "framework-agnostic, zero dependencies" actually means in practice. ## What NudaUI is NudaUI is a catalog of 1503 copy-paste UI animations spread over 81 categories — loaders, toasts, skeletons, hover cards, command palettes, waveform scrubbers, watch faces, and a long tail of effects most teams end up hand-writing at 11pm. Every entry is plain HTML and CSS, with a little vanilla JavaScript only where interactivity genuinely requires it. There is no package to install. You open a component, copy the markup and the stylesheet, and paste them into whatever you are already building. That is the entire distribution model, and it is deliberate: the code becomes yours the moment it lands in your repo, so nobody can deprecate it, break it in a minor release, or make you migrate. ## Why it exists Most animation libraries assume you are building a React single-page app with a bundler and a design-system fork. That assumption leaves out an enormous amount of real software: Laravel and Django and Rails apps, Astro and Hugo sites, internal admin tools, WordPress themes, and the plain `.html` file somebody is still shipping to production. Those teams end up pulling 200 kB of JavaScript to get a loading spinner, or writing keyframes by hand and getting `prefers-reduced-motion` wrong. NudaUI exists to remove that trade-off. The markup is the product, and markup is universal. If your stack can render a `
`, it can render every component here — unchanged, with no adapter and no build step. ## How components are built Every component in the registry follows the same rules, and they are enforced by tests rather than by good intentions: - **No frameworks, no dependencies.** Pure HTML and CSS; vanilla JS only when a component needs state. Nothing imports a runtime. - **Namespaced classes.** Every class is prefixed `nuda-*`, so nothing collides with Tailwind utilities or your own stylesheet. - **Themed with custom properties.** Colour, size, radius and timing read from CSS variables. Override them on `:root` or any parent — no Sass, no config fork. - **Accessible by default.** Motion-heavy components ship a `prefers-reduced-motion` fallback; interactive ones ship focus-visible styles, ARIA roles and keyboard handling. - **GPU-friendly.** Animations stay on `transform` and `opacity`, and flicker is kept under three flashes per second so nothing trips WCAG 2.3.1. - **Responsive.** Components work from a 320 px phone to a wide desktop without media-query surgery on your side. ## Who builds it NudaUI is designed, built and maintained by [Santiago Gómez de la Torre Romero](https://sgomez.dev), a software engineer working in Spain. He is the sole creator, owner and maintainer of the project — there is no company behind it and no team to escalate to. Bug reports and component requests go to [GitHub](https://github.com/sgomez-dev/nudaui); everything else reaches him at [contact@nudaui.dev](mailto:contact@nudaui.dev). ## Licensing and cost Component code is MIT licensed.
