Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Outline
- Requires an external SSO/OAuth provider for authentication, adding setup friction.
- No database/table views or relational data like Notion.
- Licensed under BSL (not fully open source / has usage restrictions).
- Fewer block types and no whiteboard/canvas features.
Stirling-PDF
- Not a document-management or collaboration tool — purely a PDF processing utility.
- Advanced features like user auth and SSO require the paid Stirling-PDF Pro license.
- No document storage or versioning; files must be uploaded and downloaded manually each session.
- OCR accuracy depends on Tesseract language packs installed in the container.
Bottom line
Choose Stirling-PDF if you want the lower-effort setup; choose Stirling-PDF for the larger community and ecosystem. Open each guide below for deploy steps and the full feature gap.
