Portainer is mentioned by the author in the README:

“What spurred me to build Isaiah in the first place is a bunch of comments on the Reddit self-hosted community, stating that Portainer and other available solutions were too heavy or hard to use.”

Yacht (https://yacht.sh/) is good too if anything about Portainer upsets you.

Looks like a clone or fork of the UnRaid docker interface

I had weird Windows boot lag with Portainer. Like minutes. No containers were even active or running. Uninstalled and it went away.
