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' => 'http://mysite.com/',
        'direction' => 'ltr',
        'attributes' => [
            'foo' => 'bar',
        ],
    ]
]

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

{{ site }}

default

As a tag pair, you can access additional information:

{{ site }}
    {{ handle }}
    {{ name }}
    {{ locale }}
    {{ short_locale }}
    {{ url }}

    {{ attributes }}
        {{ foo }}
    {{ /attributes }}
{{ /site }}
