Out of the box, Pulsar cannot run Visualforce pages, Lightning Components, and Apex triggers offline because they require the Apex Framework to run. However, there are ways to achieve the same functionality in Pulsar.
What is Apex?
Apex is a strongly typed, object-oriented programming language that allows developers to execute flow and transaction control statements on Salesforce servers in conjunction with calls to the API. Using syntax that looks like Java and acts like database stored procedures, Apex enables developers to add business logic to most system events, including button clicks, related record updates, and Visualforce pages. Apex code can be initiated by Web service requests and from triggers on objects. All Apex runs entirely on-demand on the Lightning Platform. Developers write and save Apex code to the platform, and end users trigger the execution of the Apex code via the user interface. Apex is compiled, stored, and run entirely on the Lightning Platform. When a developer writes and saves Apex code to the platform, the platform application server first compiles the code into an abstract set of instructions that can be understood by the Apex runtime interpreter, and then saves those instructions as metadata.

Why can’t Pulsar run Apex code?
So given the above explanation, it is now clear that Apex code can’t run anywhere other than Salesforce platform since it requires the Lightning Platform which is proprietary to Salesforce.
What can be done about it?
There are two ways to solve this problem.

Method 2: If you need similar functionality to run when you are completely offline, Pulsar can accommodate that. However you will need to rewrite these pages or triggers using one of the two methods Pulsar has to offer. You can use Pulsar as a platform and HTML/Javascript or the Pulsar Settings Language (PSL) to create a custom Pulsar app to perform the same tasks offline.
