Has anyone heard of / tried OPNexus for central OPNsense management?

[dev]

Hi everyone,I've come across a project called OPNexus (https://opnexus.dev and https://github.com/OPNexus-dev/OPNexus).
It presents itself as a self-hosted central management console for multiple OPNsense firewalls. But for free.

It is source-available (PolyForm Shield license), runs via Docker Compose, and claims to work purely through the OPNsense API.
I couldn't find any discussion about it in the OPNsense forum or elsewhere, so I wanted to ask:Has anyone here heard of OPNexus before?
Has anyone already tested or is currently using it?
Any experiences, impressions, or concerns (positive or negative)?

Thanks in advance for any feedback!
