# Inspector

The inspector UI for UnoCSS: `@unocss/inspector`.
Ships with `unocss` and `@unocss/vite`.

## Usage

Visit localhost:5173/\_\_unocss in your Vite dev server to see the inspector.

The inspector allows you to inspect the generated CSS rules and the applied classes for each file. It also provided a REPL to test your utilities based on your current configuration.
