What UI component libraries have you used?

I have used several popular UI component libraries:

• Material-UI (MUI) — provides ready-made components in Material Design style, easy to customize, and well-documented.
• Ant Design — a rich set of components with thoughtful design and theming support.
• Bootstrap — a classic library with a grid system and basic components, often used for quick layout.
• Chakra UI — a modern library focusing on accessibility and simple styling through styled components.

The choice depends on the project requirements, design, and team preferences.
