That sounds like a pretty cool project

It’s simpler/more lightweight than WordPress, but generally yes (don’t know squarespace)

Yes, I think I’m getting your original question now. I didn’t even look into their hosting offers because I’m actively looking for things I can self host. It’s the same reason I self host many things, I don’t care if someone else offers it for free. I’m 100% owning it, I don’t have to rely on someone else’s server, and I enjoy the process of setting up my own infrastructure, figure out ways to make it reliable etc. It’s also a learning experience for me.

Against random internet noise? Yes, absolutely

How, if it’s not exposed to the internet? Burglars?

Yes, but I don’t plan to host bitwarden. I was referring to op’s question regarding vaultwarden+auth. Sorry, I think I can’t follow you

I don’t?

No, but Vaultwarden is the one thing I don’t even try to connect to authentik so a breach of the auth password won’t give away everything else
