According to Docspring, their solution makes it easy for developers to fill out PDF forms. While sporting many of the same features as PDF Generator API, Docspring does not have the capability to conditionally hide pages, iterate over a list of items nor conditionally format and hide components. Furthermore, Docspring does not offer using the same templates across different workspaces or template versioning. Using Docspring will set you back $49/1000 merges.
