InvenTree vs Part-DB | Unicorn Factories

InvenTree and Part-DB compete in the open-source parts inventory management space, both offering web-based interfaces for tracking components across multiple locations. They solve similar problems but with different design philosophies and target audiences.

Core difference

Part-DB is purpose-built for electronic components and makers. Its standout feature is native KiCad 8+ integration through HTTP libraries, letting PCB designers browse stock levels and pull component data directly into their EDA workflow. It connects to electronics distributors (Octopart, DigiKey, Mouser, Farnell, TME) for automatic part metadata and pricing. The permission system supports SAML SSO through Keycloak, making it suitable for university labs and makerspaces.

InvenTree takes a broader approach. While it handles electronics fine, it is not limited to them. The BOM management and build order system suit general manufacturing and assembly workflows. The plugin architecture supports label printers (Zebra), barcode scanning, and custom extensions beyond the electronics domain. InvenTree also offers a native mobile app, whereas Part-DB relies on its responsive web interface.

Architecture comparison

Capability	InvenTree	Part-DB
Primary focus	General parts inventory	Electronic components
EDA integration	Via plugins/API	Native KiCad 8+ HTTP library
Distributor APIs	Manual/API integration	Built-in Octopart, DigiKey, Mouser, Farnell, TME
BOM management	Yes, with build orders	Yes, with project-based withdrawals
Mobile app	Native iOS/Android	Responsive web only
Tech stack	Python/Django	PHP/Symfony
License	MIT	AGPL-3.0

When to choose InvenTree

You manage non-electronic inventory alongside electronics
You need build orders and production workflow tracking
You want a native mobile app for inventory operations
You prefer Python ecosystem and MIT licensing
You need plugin extensibility for custom integrations

When to choose Part-DB

You work primarily with electronic components
You use KiCad 8+ for PCB design and want seamless library integration
You want automatic part metadata from major electronics distributors
You need SAML/SSO authentication for multi-user environments
You prefer the PHP/Symfony stack

Can they coexist?

Generally no — both want to be your source of truth for parts inventory. However, a large organization might use Part-DB for R&D electronics and InvenTree for production inventory, syncing via their respective REST APIs.
