Stirling PDF: Self-Hosted Platform for PDF Editing and Document Workflows

RepositoryStirling-Tools/Stirling-PDFTool

Stirling PDF is an open-source PDF manipulation platform designed to run as a desktop client, in a browser, or self-hosted on private servers. It provides over 50 tools, REST APIs, and no-code pipelines to process documents without relying on external cloud providers.

Key points

  1. Offers more than 50 PDF tools covering editing, splitting, merging, signing, redacting, converting, OCR, and compression.
  2. Ensures document privacy through self-hosted deployments via Docker, Kubernetes, or standalone desktop installations.
  3. Supports workflow automation using a no-code visual pipeline in the UI alongside REST APIs for external integration.
  4. Includes enterprise-ready features such as single sign-on (SSO), audit trails, and on-premises controls.
  5. User interface is localised in over 40 languages.

Why it matters

Online PDF utilities frequently pose security and privacy compliance challenges because files are uploaded to third-party servers. Stirling PDF removes this exposure by offering an entirely local or private-cloud solution.

Analysis

Built primarily in Java and distributed via Docker and native binaries, Stirling PDF demonstrates high production maturity with over 91,000 GitHub stars and extensive enterprise adoption features. It serves individual users needing local desktop tools, software developers integrating PDF APIs, and organisations requiring privacy-compliant document pipelines.
