Fleet (FleetDM) is an open-source device management platform built on osquery that gives IT and security teams SQL-queryable visibility into endpoints alongside full cross-platform MDM for macOS, Windows, Linux, iOS, iPadOS, Android, and ChromeOS.
Founded in November 2020 by CEO Mike McNeil and CTO Zach Wasserman, and headquartered in San Francisco, Fleet grew out of the osquery ecosystem that Wasserman helped create at Facebook in 2014, later building on the Kolide Fleet osquery control server before spinning out as its own company.
Key Features
Fleet combines osquery-based live and scheduled SQL querying of device state with native MDM functionality: enrollment, configuration profiles, remote lock and wipe, software deployment, and OS update enforcement.
The platform is API-first and GitOps-native, letting teams manage device policy as version-controlled YAML, and it supports SSO, webhooks, and self-hosted or air-gapped deployment on every pricing tier.
Pricing
Fleet's core is free and MIT-licensed, self-hostable at no cost with device inventory, policies, the REST API, GitOps, SSO, and community support. Fleet Premium starts at $7 per host per month and adds MDM migration, zero-touch and BYOD enrollment, conditional access, application deployment, script execution, remote lock and wipe, and continuous vulnerability scanning with phone and email support.
A Custom tier is available by contacting sales for large-scale deployments, and Fleet's own managed cloud hosting is currently limited to organizations with 700 or more hosts.
Key Features
Cross-platform MDM — Manages macOS, Windows, Linux, iOS, iPadOS, Android, and ChromeOS from a single console.
osquery-powered visibility — Exposes device state as SQL-queryable tables for live and scheduled querying across the fleet.
GitOps configuration — Device policies and settings can be defined as YAML in version control and deployed through CI pipelines.
REST API and webhooks — Full API access and webhook integrations let teams automate workflows and connect Fleet to external tools.
Zero-touch and BYOD enrollment — Premium tier supports automated device provisioning and bring-your-own-device enrollment.
Continuous vulnerability management — Cross-references installed software against known CVEs for ongoing risk visibility.
Remote script execution and lock/wipe — Run scripts remotely or lock and wipe devices directly from the console.
Self-hosted and air-gapped deployment — Fleet can be deployed entirely on infrastructure the customer controls, including disconnected environments.
