ESS Orrery
Operator control plane for a fleet of Linux boxes

Know every box in your fleet is exactly as you declared.

One mechanism, many bodies, held in true.

ESS Orrery is software you install that holds the declared shape of your whole fleet (any provider, any Linux box) and proves, continuously and read-only, that reality still matches it. Six checks surface drift the moment it appears. It measures and reports, it never changes your boxes.

See the whole fleet in true, at a glance.

One instrument for a mixed fleet. Any provider, any Linux box, from a solo operator's handful to an org across regions. Drift surfaces the moment reality diverges from what you declared. The deck below is illustrative.

The six checks, in detail, live on the reconciler page. / See how it compares.

Run it against your own fleet.

Install the core, verify it, then reconcile against a profile you declare. Read-only, so the first run cannot break anything.

pip install orrery && orrery doctor
