Add-ons

Add-ons extend the usage rights of any base licence. They are activated immediately — your purchase confirmation email and order ID serve as the authorisation document. No separate licence file is issued.

OEM Redistribution

+€1,999

Right to bundle and distribute the PDFluent SDK as part of a compiled commercial software product you sell to end users. End users of your product do not need their own PDFluent licence.

Includes

  • Redistribution inside your compiled binary or package
  • End-user deployments without separate PDFluent licence
  • All tiers (Lite through Unlimited)

Does not cover

  • Building a competing PDF SDK or document-processing platform
  • Redistributing the SDK as a standalone developer product

Active immediately. Your purchase confirmation email and order ID constitute the OEM Redistribution License. No separate licence file is required.

Air-gapped Deployment

+€1,499

Right to deploy PDFluent in environments with no outbound internet connectivity. Licence validation is fully offline — no network request at runtime.

Includes

  • On-premise and isolated cloud deployments
  • Government, defence, and regulated environments
  • Environments where outbound connections are prohibited

Active immediately. Your purchase confirmation email and order ID confirm this right. No separate licence file is required.

Open-source foundation crates

PDFluent is built on a foundation of low-level crates that are forks of upstream open-source libraries (lopdf, hayro, cff-parser). These crates remain under their original permissive licenses and may be used standalone without a commercial key. They are listed below for transparency. The PDFluent commercial value (engine, forms, signing, redaction, compliance, render, font, XFA) is in the proprietary crates published under the PDFluent Commercial License.

pdfluent-lopdfMITLow-level PDF object model — fork of lopdf

These are the only crates published by PDFluent under permissive licenses. All other published crates ship under the PDFluent Commercial License — see /terms for the full terms.
