I built this because I needed it.

First, I built the hard version.

Before Astral Warden, I did what an engineer does: I wired up Prometheus, wrote custom exporters for gear that exports nothing, ran a VPN to reach the rig behind its firewall, and built dashboards to watch it all. It worked. It also took more effort to build and keep running than the product you're looking at now, and I had to constantly adjust it for every change to my rigs.

The failures that actually cost me nights were never the ones that threw errors. A plate-solve loop. A guiding problem. A sequence that never started. FWHM quietly doubling. My rig looked “up” the whole time and produced nothing worth keeping.

Then I made it something you can just drop in.

Astral Warden is that monitoring, without the engineering. One small, read-only agent on your scope PC. No server to run, no VPN, nothing to ask your host for. It watches the whole stack, from the machine and NINA or Voyager to the mount, the guider, power, weather and the subs themselves, and it knows what “good data” means, because it was built by someone chasing the same keepers you are.

It's opinionated on purpose. I'm not trying to sell you a box of dials to configure. I'm trying to give you the thing I wanted the whole time: to know, from anywhere, that my rigs are healthy and my data is good, and to be told the moment they're not.
