**Related issue:** N/A ## Summary Fleet's "Host vitals" label type already supports matching on a custom host vital's exact value (in addition to the existing IdP-based criteria), but this wasn't documented anywhere outside the custom host vitals guide (see companion PR #50660). Adds that coverage across the remaining references: - `articles/managing-labels-in-fleet.md`: the "Host vitals" label type bullet only listed the two IdP criteria; now also mentions custom host vitals, and notes the type is exact-match only. - `docs/Configuration/yaml-files.md`: - Adds a `custom_host_vital` example to the labels GitOps reference, alongside the existing IdP example. - Adds a new `## custom_host_vitals` section documenting the top-level GitOps key used to define vitals in the first place (referenced by the labels criteria above), which had no reference-doc coverage at all. Calls out that, unlike `labels`, omitting the key entirely deletes every existing custom host vital rather than leaving them intact. - `docs/REST API/rest-api.md`: - The `criteria` parameter table was missing `custom_host_vital` as a valid `vital` value and missing `custom_host_vital_id` entirely — added both. - None of the 6 registered custom host vitals endpoints (list, create, update, delete, set a host's value, and the spec/replace-all endpoint GitOps uses) had reference entries at all. Adds a full "Custom host vitals" section following the existing "Custom variables" section's format, including the same destructive replace-all behavior called out in the YAML reference above. # Checklist for submitter - [ ] QA'd all new/changed functionality manually --------- Co-authored-by: Rachael Shaw <r@rachael.wtf>

Open-source platform for IT and security teams with thousands of computers. Designed for APIs, GitOps, webhooks, YAML, and humans.
What's it for?
Fleet gives you a single system to secure and maintain all your computing devices over the air. You can do MDM, patch stuff, deploy software, and verify anything, all from one place, across every OS your organization uses.
Fleet works directly with data and events from the native operating system, down to the bare metal. Strong diagnostics let you investigate errors on end-user devices and collect accurate audit evidence in minutes.
Get started
You can try Fleet out for yourself, or grab time with one of the maintainers to chat.
Is it any good?
Fleet is used in production by IT and security teams managing thousands of devices. Many deployments support tens of thousands of hosts, and a few large organizations manage 400,000 or more.
Supported platforms
- Linux (all distros)
- macOS
- Windows
- Chromebooks
- iOS and Android (BYOD or corporate-owned)
- Amazon Web Services (AWS)
- Google Cloud (GCP)
- Azure (Microsoft cloud)
- Data centers

Infrastructure as code
Manage your fleet with GitOps, or use the GUI, REST API, webhook events, and the fleetctl command-line tool.
Linux support
First-class support for all major distros. Linux gets the same attention and visibility as macOS and Windows.
Visibility and compliance
Fleet can report on hundreds of attributes across your devices and ships with CIS benchmarks for macOS and Windows and comprehensive operating system, hardware, and software data. Check out the table reference documentation to see what's available.
Open by design
Fleet is open source and transparent about what it can and can't see. End users can verify exactly how the agent works and what data their company collects. Fleet collects only the data needed to manage and secure devices, not private activity like keystrokes, emails, or webcams.
Good neighbors
Ready-to-use, enterprise-friendly integrations exist for Snowflake, Splunk, GitHub Actions, Vanta, Elastic Jira, Zendesk, and more. Fleet also works with tools such as Munki, Chef, Puppet, Ansible, CrowdStrike, and SentinelOne.
Lighter than air
Fleet is lightweight and modular. You can use it for MDM without using it for security, and vice versa. You can turn off features you are not using.
Free as in free
The free version of Fleet will always be free. Fleet is independently backed and actively maintained with the help of many amazing contributors.
Longevity
The company behind Fleet is founded (and majority-owned) by true believers in open source. The company's business model is influenced by GitLab (NYSE: GTLB), with great investors, happy customers, and the capacity to become profitable at any time.
