Yggdrasil Core

The open-source engine.

Run it on servers, workstations, home labs, or build your own client against its APIs.

Core is the daemon, the local web UI it serves, and the HTTP API in front of local models. It is licensed AGPL-3.0-or-later. Yggdrasil Desktop and Yggdrasil Mobile are separate products and are not developed in the Core repository.

Open source

Community contributions are welcome. Hardware reports, runtime notes, documentation, and code all help. Nothing in the software is gated on a donation.
