It's written in Go with no dependencies (or database). My intention was for an AWS image or something companies could run inhouse air-gapped from the Internet. Something like $10/m or so.
The cli is pretty easy to integrate with scripts: https://github.com/thisdougb/doocot
Longer term secrets were something I was looking at too. Pretty easy to extend this, but encroaches on Vault products and I felt that a harder sell to CTOs.
I've worked in infra/systems dev for years, and this sort of thing was bread and butter stuff.
Maybe I'll resurect it as an active project. What sort of feature/tool would get you to stop using Discord/Slack/etc for secrets?
