## What it is
Layui is an open-source, MIT-licensed Web UI component library built with vanilla HTML, CSS, and JavaScript, offering a lightweight modular system of components like tables, forms, popups, and date pickers. It targets developers who want to build web interfaces without build tools or mainstream frameworks, working directly against the browser.

## Use cases
- build admin dashboard interfaces without a build toolchain
- add modals, popups, and dialogs to plain HTML pages
- render data tables with pagination and tree tables
- create forms with selects, checkboxes, and upload widgets
- add date and time pickers to server-rendered pages
- quickly prototype web UIs with CDN-included components

## When to choose
- you want a UI library that works with plain HTML/CSS/JS and no bundler
- you're maintaining or building classic server-rendered web apps
- you need a lightweight, batteries-included component set out of the box
- you prefer minimal tooling and browser-native development

## When to avoid
- you're building a modern SPA with React, Vue, or Angular
- you need TypeScript-first tooling or a large npm ecosystem
- your team prefers component frameworks with virtual DOM and state management
- you need cutting-edge frontend patterns the project itself recommends mainstream frameworks for
