Novamira HQ beta3 is out, and it brings a new hosting company into the app: xCloud.
Connect your xCloud account with an API token and every WordPress site in it, staging sites included, shows up in Novamira HQ next to the rest, reachable by hand in the dashboard or through your AI.
From there you can create backups, and the xCloud page in the docs has the full picture.
Novamira HQ is free and open source, in beta, for macOS, Windows and Linux. Get it from the HQ page and find the setup in the documentation.
