Stirling PDF runs in Docker on your NAS or homelab with dozens of PDF utilities in one web UI. Keeps document processing local—no uploading tax forms to random online PDF SaaS tools.
The catch
Docker setup required; overkill if PDFgear desktop already covers your needs.
Good fit for
- Homelab users
- Families batch-scanning paperwork
Not ideal for
- Non-technical users needing one-click mobile edits
