Oat is an ultra-lightweight (~10KB min+gz), zero-dependency UI component library built on semantic HTML, CSS, and vanilla JS WebComponents. It styles native elements contextually without classes, requiring no framework or build step.

Use cases

• build a decent-looking web app without a JS framework
• style semantic HTML with no CSS classes
• add a lightweight UI kit to a server-rendered site
• avoid npm dependency bloat in frontend projects
• get accessible components with keyboard navigation out of the box
• quickly theme a dashboard with CSS variables and dark mode

When to choose

• you want zero dependencies and no build tooling
• you prefer semantic HTML over class-heavy markup
• you need a tiny footprint for dashboards or internal tools
• you value accessibility and standards-based vanilla CSS/JS

When to avoid

• you need a rich component ecosystem or complex state management
• you're building a highly interactive SPA with React/Vue
• you require a stable v1 API (project is pre-v1 with breaking changes)
• you need extensive custom design beyond CSS variable theming
