Lit is a small (~5 KB) TypeScript library for building fast, lightweight web components on top of browser standards. It provides a reactive base class, scoped styles, and an efficient declarative HTML template system (lit-html) that only updates dynamic DOM parts.

Use cases

• build reusable web components
• create a design system usable across frameworks
• build a fast lightweight single-page app without a heavy framework
• progressively enhance server-rendered or CMS-driven HTML pages
• share components between React, Vue, and plain HTML apps
• add interactivity to static sites built with Jekyll or eleventy

When to choose

• you want framework-agnostic components that work anywhere HTML works
• bundle size and rendering performance are priorities
• you're building a shareable component library or design system
• you want minimal lock-in and easy incremental migration

When to avoid

• you need a large ecosystem with batteries-included routing, state, and data layers
• your team is already deeply invested in React or Vue conventions
• you need mature SSR out of the box (Lit SSR is still in labs)
• you require extensive mobile-native support
