It's not self-hostable yet: I'm thinking about adding this option. I think for now I'm trying to see if people would like to give it a shot and try it out.
Because when I'm running infra just to manage scripts for me I want them in proximity to other apps or services I'm already running. There's very few SaaS that will offer a way to connect privately (e.g. Tailscale).
Ultimately I want this in my stack. Autokitteh let's me do it my way, so this is a deal breaker for me. I also don't want to get stuck in SaaS only to have it enshittififed in a few years.
Why do you think it's a deal breaker for you?
