Open QuarterMaster

Open QuarterMaster provides a self‑hosted inventory database that tracks what is stored, where it is located, and related facts through a central Core API. A web‑based Base Station frontend gives users direct access to the inventory, while a plugin architecture lets developers add specialized capabilities such as smart‑refrigerator integration, point‑of‑sale interfaces, or workflow management. The system is built from modular containers, allowing deployment on anything from a cloud server to a Raspberry Pi.

The software targets organizations of any size that need a flexible, scalable solution for managing stock, supplies, or assets without vendor lock‑in. Because it is open source under GPL‑3.0, users can run it without subscription fees, modify the code, and contribute improvements. Its design emphasizes extensibility, so users can tailor the platform to specific workflows by adding or creating plugins.

Distinctive aspects include a clear separation between the generic inventory engine and optional extensions, container‑based deployment for easy environment switching, and a community‑driven development model that encourages customization while keeping the core system stable and free.
