The self-hosted option when privacy and batch operations matter more than desktop-app gloss.
licenseMIT
runsyour machine or their cloud
installInstall the native Windows/macOS desktop build, run the Linux JAR, or deploy the documented Docker image/Compose stack; a hosted cloud edition also exists
dataDesktop and self-hosted deployments process files on the user's machine/server and can use mounted local storage; the cloud edition uploads files for transient server processing
the catch vs Nitro PDF ProIt excels at private batch operations, but its direct page editing, collaboration, managed e-signing, and desktop polish are weaker than Nitro's.
setupThe native desktop app is simple, but a full private cross-platform service and automation setup is most reliably deployed with Docker

why people still pay for Nitro PDF Pro
People still pay for Nitro PDF Pro because the visible editor is reproducible, but reliable rendering and legally defensible signature workflows are not a casual side project. The recurring cost buys format edge cases, fonts, rendering, encryption, signatures, evidence, retention, storage, backups, and legal requirements, not just the visible interface. If none of that applies to you, any pick above saves $180 a year.
