FleetOS — one canonical record for every machine you run

FleetOS is the shared inventory of every machine your org runs — the one place that answers "what do we actually have, and what state is it in." It is the host layer other operations tools build on top of.

One record per host:

Every managed machine gets one canonical record with its hardware and OS facts, IP and MAC, and its last-seen and reachability state. That record is the single source of truth for that host, no matter which tool touches it.

Every kind of machine:

FleetOS is deliberately mixed-estate. A host can be Linux, Windows, network gear, a container, a VM, or a TurtiniOS appliance — they all live in the same inventory under the same record shape, so you are not stitching together a separate tool per platform.

Static and dynamic groups:

You can put hosts into static groups you curate by hand, or dynamic groups defined as a saved query over facts and tags. A dynamic group keeps itself current — "every Ubuntu 22.04 host in the east region" stays accurate on its own as hosts check in and their facts change. You never re-tag a dynamic group; it re-evaluates itself.

Keeping the inventory live:

Hosts check in either with an agent or agentless, which keeps facts and reachability fresh. Patch and drift posture surface right on each host record, so you can see at a glance which machines are behind or have drifted from their expected state.

Where it fits:

FleetOS is the keystone inventory for the broader operations line — the same host records feed maintenance, security posture, and fleet-wide actions, so you define a machine once and every operations surface sees the same truth about it.
