Fleet UI

Fleet UI is the GUI (graphical user interface) used to control Fleet. Docs.


Fleetctl (pronouced “fleet control”) is a CLI (command line interface) tool for managing Fleet from the command line. Docs.


Fleetd is a bundle of agents provided by Fleet to gather information about your devices. Fleetd includes osquery, Orbit, Fleet Desktop, and the Fleetd Chrome extension.

Orbit is an osquery version and configuration manager, built by Fleet.

Fleet Desktop

Fleet Desktop is a menu bar icon that gives end users visibility into the security and status of their machine. Docs.

Fleetd Chrome extension

The Fleetd Chrome extension enrolls ChromeOS devices in Fleet. Docs.


A host is a computer, server, or other endpoint. Fleet gathers information from Fleet's agent (fleetd) installed on each of your hosts. Docs.


A team is a group of hosts. Use teams to segment your hosts into groups that reflect your organization's IT and security policies. Docs.


A query in Fleet refers to an osquery query. Osquery uses basic SQL commands to request data from hosts. Use queries to manage, monitor, and identify threats on your devices. Docs.


A policy is a specific “yes” or “no” query. Use policies to manage security compliance in your organization.
