There is not. This is a feature request: Grab current page URL with liquid.
Workaround
If you have several different instances but just wants to use a single liquid variable, then you can achieve this with a clever application of User Attributes.
- On each instance, create a User Attribute called "hostname".
- Set the default value of "hostname" to the hostname URL. This will differ per instance, of course.
- In your LookML, reference
{{ _user_attributes['hostname'] }}to get the hostname URL!
