I used to run it and generally liked it, but eventually felt limited in the things I could do. At the time it was a hassle to run non-tipi apps behind the traefik instance and eventually I wanted SSO.

I ended up in a similar place with proxmox, docker-compose, and portainer but I have it on my backlog to try a competitor, Cosmos, which says many of the things I want to hear. User auth, bring your own apps and docker configs, etc.
