Basic Usage

Enable the debug module in your application configuration (config/web.php).

if (YII_ENV_DEV) {
    $config['bootstrap'][] = 'debug';
    $config['modules']['debug'] = [
        'class' => \yii\debug\Module::class,

The toolbar appears at the bottom of every rendered page; click any panel chip to open the full debugger.
