Stirling PDF
PDF Infrastructure for Developers — secure, open-source, self-hosted
Stirling PDF is an open-source PDF platform that provides APIs, SDKs, an AI agent toolkit, and a self-hosted editor for processing sensitive documents entirely on your own infrastructure. It is designed for enterprises that require air-gapped, HIPAA-compliant, or firewall-restricted document workflows. Trusted by over 55,000 companies including 75% of the Fortune 500, it has surpassed 25 million downloads.
Stirling PDF is deployed on a user's own infrastructure (bare metal, private cloud, or air-gapped environments) and exposes PDF APIs, MCPs, and an editor that process documents locally without any data leaving the machine.
