## What is Cascadia PLM?

Cascadia PLM is an open source product lifecycle management platform for teams who ship physical products. Available on GitHub under AGPL-3.0 and free to self-host on your own infrastructure. Manage parts, BOMs, documents, requirements, and change orders with Git-style versioning and full data ownership.

## Key Value Propositions

- **Full data ownership**: Your PostgreSQL database, exportable anytime.

## Core Features
