The list is pretty similar to hbd. Hbd doesn’t have transmission and syncthing, and prowlarr is semi-official but instead they have Medusa, autobrr, filebrowser and resiliosync.
Will check out the wiki :) If you have ssh enabled in your box, I would suggest looking up SSH keys. I have some public stuff I run for my work and I get at least a hundred brute force attacks on port 22 when I use a password.
How is there customer support infrastructure? With hbd I can raise tickets or talk on discord where they answer pretty fast.
