Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
SilverBullet
- No native mobile apps; mobile use relies on the web interface
- Real-time multi-user collaboration is limited compared to cloud-first tools
- Plugin ecosystem is much smaller than Obsidian's community plugin library
- No built-in rich media embedding or database views comparable to Notion
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
Both are a similar lift to self-host; choose Stirling-PDF for the larger community and ecosystem. Stirling-PDF has seen more recent development. Open each guide below for deploy steps and the full feature gap.
