Cannery

Cannery is a self‑hosted application for recording and managing personal firearm and ammunition inventories. Users can create entries for individual weapons, track quantities of ammunition, and organize related details such as calibers, serial numbers, and maintenance records. The system stores data locally, allowing owners to run the service on their own hardware without reliance on external cloud providers.

The software is released under the AGPL‑3.0 license, making the source code freely available and modifiable. It offers a free tier with all core functionality and does not require any subscription fees, positioning it as a cost‑free solution for individuals or small groups that need a private, controllable tracker. Its design emphasizes simplicity and stability, and it is marked as stable for production use.

Because it is open source and self‑hostable, users can inspect, customize, or extend the code to fit specific workflow requirements while retaining full control over their data and deployment environment.
