Get paths of all open webforms
You can do it in a custom module using entity.query service 

$query = $this-&gt;entityTypeManager()-&gt;getStorage('webform')-&gt;getQuery();
$webform_ids = $query-&gt;condition('status', 'open')-&gt;execute();

$webforms = Webform::loadMultiple($webform_ids);
$webform_urls = [];
foreach($webforms as $webform){
  $webform_urls[] = $webform-&gt;toUrl()-&gt;setAbsolute()-&gt;toString();
}


Here is a demo module that uses entity.query in a controller to output those path as links with title as the title of each webform.
