Celestial Altium Library

Free cloud-hosted Altium database library with 200,000+ components and full 3D models

Servicefree

The Celestial Altium Library is a free, open-source component database for Altium Designer with more than 200,000 parts, including footprints and 3D models. It is hosted in the cloud so newly added components appear in Altium immediately, with symbols and footprints also available from GitHub. It is aimed at PCB designers who would otherwise build and maintain their own component library.
