One of the first tasks I had for Claude was to build a protected KV store out of keepassx.cli. Out of the box I got a beautiful gui for seeding initial secrets while giving me a nice scriptable, non-interactive tool for injecting secrets into infrastructure bootstrapping.
"also" is a strong word for a project this young. It was started in October 2025, does not have any issues (at all) and is completely vibe coded. Not starting a discussion about security & vibe coding now, but I wouldn't blindly recommend such a nascent project if compared to something mature like SOPS.
