Which NAS devices work with the Seedr Connector?

Synology, QNAP, TrueNAS SCALE, Unraid, any Docker host, or a Linux machine.

These work with the Seedr Connector:

Synology: Container Manager. Add the registry https://ghcr.io first, or use a Compose project.
QNAP: Container Station.
TrueNAS SCALE: Custom App.
Unraid: Docker, Add Container.
Any machine with Docker or Docker Compose.
Linux without Docker: run the binary (amd64, arm64 or armv7) under your NAS service supervisor.

The Docker image is ghcr.io/seedrcc/seedr-connector:1.0.0. Full steps are in the install guide on GitHub. See also the Seedr guide.
