Came here to post this as well. Only started down the homelab / self host route and this developer helped me tremendously. In his post, they say they’re on hospice and that development will slow. If it brings you joy Godspeed, but if not, you owe the community nothing. Thank you and may you be as comfortable as possible.

Here's his update:

This is sad to hear. Getting into homelab, I rolled my own -- but quickly found myself setting up lxc's with tteck. Incredible resource.
