Dokuly is a free, open-source Product Lifecycle Management system for engineering and operations teams. It manages parts, PCB assemblies, assemblies, bills of materials, revisions, releases, and alternate parts. Document controls include automatic numbering, revision management, PDF front-page generation, a built-in viewer, and browser editing through OnlyOffice. Purchasing covers suppliers, price breaks, purchase orders, and order tracking, including selection of the cheapest supplier for BOM orders. Inventory and production features track stock locations, transactions, lots, serial numbers, and assembly progress. Requirements can be linked hierarchically or as derived and superseding items, with verification tracking; engineering change orders record affected items for review. Projects provide access control, time tracking, tasks, and Gantt charts. Dokuly runs as a self-hosted Docker stack using PostgreSQL, Django, and nginx. Integrations include DigiKey API, Nexar API, and OnlyOffice. Its REST API uses project-scoped keys with configurable expiry and includes Swagger and ReDoc documentation. The documentation describes project-based API access controls; no security certification is stated on the pages reviewed.
