site

The current site being targeted in the request.

It's a Statamic\Sites\Site object and can be used as a single tag or tag pair.

// config/statamic/sites.php
 
'sites' => [
    'default' => [
        'name' => 'My Statamic Site',
        'locale' => 'en_US',
        'url' => '/',
        'direction' => 'ltr',
        'attributes' => [
            'foo' => 'bar',
        ],
    ]
]

As a single tag, it will output the handle of the site:

{{ site }}

{{ $site }}
