Show HN: Stateless On-Prem JSON-to-PDF via REST (Java)

https://github.com/onprem-pdf/onprempdf
1•TrqConverter9•1h ago
Hi HN,

I built a stateless, on-prem JSON-to-PDF generation service in Java.

Clients send JSON via REST and receive a generated PDF synchronously. No documents or payloads are persisted.

This is a commercial, proprietary on-prem product; the repository contains installation artifacts and documentation.

Feedback welcome
