Out of the box, Pulsar cannot run Visualforce pages, Lightning Components, and Apex triggers. All of these items allow customization of Salesforce and require the Apex framework to run, and that framework can only run within Salesforce.
You can use the Pulsar Settings Language (PSL) to create a custom Pulsar app to achieve the same customizations as Visualforce pages, Lightning Components, or Apex triggers provided in Salesforce.
