# Coveo Atomic library
The {doctitle} is a web component library for assembling responsive, accessible, and future-proof Coveo-powered search UIs.
Atomic components are self-encapsulated, composable, and lightweight.
Under the hood, Atomic relies on the [Coveo Headless library](https://docs.coveo.com/en/lcdf0493/) to interface with Coveo and handle the search application state.
