VibeusStirling PDF
An open-source PDF platform for editing, converting, signing, redacting, OCR, compression, and self-hosted automation.
Stirling PDF is an open-source PDF platform that can run as a desktop app, in a browser, or on your own server. It keeps documents under your control while providing tools to edit, merge, split, sign, redact, convert, OCR, compress, and process PDFs.
The project README describes more than 50 PDF tools, a private API for integrations, and no-code pipelines that can be assembled in the interface. It also documents SSO, auditing, on-premises deployment options, and a user interface available in more than 40 languages.
To try it locally, the official quick start uses the published Docker image and opens the interface at http://localhost:8080. The documentation covers other installation options, including desktop and Kubernetes deployments. The project is open-core, so the repository and its license should be checked for the exact scope of the open-source edition and any separate server or enterprise offerings.
