- Dockerized tesseract appliance: Configuring external dockerized tesseract appliance for DMS
- OCRkit appliance (eg. ABBY OCR for Linux): Configuring OCR appliance for DMS using OCRKit
- Unspecified appliance (must be controllable through ssh and mount NFS share from DMS appliance): Configuring OCR appliance for DMS
- Using the online Google Cloud Vision service by which the OCRing will be done: Configuring Google Cloud Vision OCR appliance for DMS

- OCRKit (~$75, for OS X) Ephesoft OCR (Windows, varied pricing for cloud versus on-premise versus community edition)- Integration as a stand alone OCR appliance possible: see here
- ABBYY OCR for Linux (version 9 11 CLI, competitive pricing)
- ABBYY SDK/Runtime (all platforms, USD$5,000+)
- Nuance (all platforms, USD$5,000+)
- LEADTOOLS (all platforms, USD$5,000+pricing varies according to volume OCRed)
