Part-DB is an open-source, web-based inventory management system focused on electronic components. It helps individuals and teams catalog parts, track stock and locations, and manage projects and bills of materials (BOMs) from any browser.

Key Features

• Component inventory with categories, footprints, manufacturers, multiple storage locations, and pricing
• File attachments per part (e.g., datasheets and images) with automatic thumbnail generation
• Tags, rich text descriptions, comments, and powerful filtering including parametric search
• Barcode/label generation and built-in barcode scanning via webcam
• Multi-user system with groups and fine-grained permissions, plus event log and version rollback
• Two-factor authentication (TOTP and WebAuthn/U2F) and optional SAML-based SSO
• Project management with BOMs and guided withdrawal of required components
• Import/export capabilities (including KiCad BOM import) and an API for integrations
• Supports MySQL/MariaDB, PostgreSQL, and SQLite

Use Cases

• Managing a personal electronics parts stock for hobby projects and repairs
• Shared inventory control in makerspaces, labs, and university workshops
• Lightweight component inventory and BOM tracking for small hardware teams

Part-DB provides a practical balance of inventory tracking, access control, and electronics-focused workflows like BOMs and barcode labeling. With multiple database backends and an API, it can scale from a single user setup to shared environments with controlled access.

Open QuarterMaster is an open-source inventory management system designed to be simple to use while remaining powerful and extensible. It centers on a Core API for generic inventory functions and a web-based Base Station frontend, with additional functionality provided by optional plugins.

Key Features

• Modular architecture with a central Core API that handles inventory data and location management
• Web-based Base Station frontend for browsing and managing inventory through a user interface
• Plugin system to extend functionality for specific use cases (POS, hardware integrations, workflows)
• Container-friendly design for flexible deployment across single-host, cloud, or small devices such as single-board computers
• Focus on privacy: components do not phone home by default
• Community-driven project with documentation, demo instance, and deployment guides for Debian-based hosts

Use Cases

• Small businesses and makers tracking stock, parts, and supplies across locations
• Labs, IT departments, or makerspaces managing assets, consumables, and equipment
• Integrating inventory with point-of-sale, specialty hardware, or automation via plugins

Limitations and Considerations

• Project is actively under development; documentation and feature completeness may vary between components
• Some integrations and production deployments may require manual configuration and testing

Open QuarterMaster is aimed at organizations that want a flexible, extensible inventory platform they can host and adapt. Its modular core and plugin model make it suitable for a wide range of inventory workflows, from home collections to more complex operational environments.
