## What it is
Leva is a React-first GUI component library for building customizable control panels with a single useControls hook. It offers smart input type recognition, 12+ input kinds, plugin extensibility, and zero-setup usage, commonly used for tweaking parameters in creative and 3D web apps.

## Use cases
- add a control panel to tweak react-three-fiber scene parameters
- build a settings GUI for my React app
- expose tunable parameters with sliders and color pickers in a demo
- create a debug panel for live-editing component props
- let users adjust animation values interactively in the browser

## When to choose
- you need a beautiful, zero-config control panel in a React app
- you want smart automatic input type inference from default values
- you need extensible custom input plugins
- you're building creative coding or 3D demos and want live parameter tweaking

## When to avoid
- you're not using React
- you need a production end-user settings UI with full design control rather than a developer tweak panel
- you need a framework-agnostic vanilla JS control panel
- you require long-term stability - the repo notes it is under heavy development
