Flint UI 🔥Web Components Library

A comprehensive set of accessible, customizable web components built with LitElement.

75+ Components

Buttons, data tables, date pickers, tree views, carousels, and more.

Standard web components — React, Vue, Angular, Svelte, or plain HTML.

Auto-generated bindings via @lit/react with full event and ref support.

Customize with --flint-* CSS custom properties. No build step required.

Thoroughly tested with Vitest — every component has unit and integration tests with near-complete coverage.

80% Stryker mutation score ensures tests detect real bugs, not just execute code paths.
