**Related issue:** N/A — CI improvement for the FMA validation workflows. ## Summary Restructures the Windows and macOS Fleet-maintained app validation workflows around a cheap Linux detect/shard job, with Windows apps additionally routed to a CI runner whose native architecture matches the app's installer. **Both platforms:** - Change detection and sharding run on `ubuntu-latest`. Expensive Windows/macOS runners only spin up when their platform actually has changed apps — e.g. a Windows-only letter-batch PR no longer boots a macOS runner just to discover there's nothing to do (and vice versa) — and they check out at depth 1 instead of full history. - A new `.github/scripts/partition-fma-apps.sh <windows|darwin>` emits the job matrix; validation steps move unchanged into reusable workflows (`test-fma-windows-validate.yml`, `test-fma-darwin-validate.yml`). - Large PRs shard into parallel jobs (Windows: 25 apps/shard, macOS: 30), and the manual full-run workflows gain a `shard_size` input (Windows default 20 → ~20 shards over 384 apps; macOS default 25 → ~39 shards over 961 apps). Neither full run could previously finish: hundreds of sequential installs blow the 6-hour job limit. - Pre-installed app handling is computed per shard from that shard's slug list — Windows removals (Chrome, 7-Zip, Firefox, Node.js, PowerShell, R, Git) and macOS steps (Chrome, Xcode for Icon Composer, the Fleet Desktop MDM config stub) only run on the runner validating that app. This also brings the full-run workflows to parity with the PR gates (they previously only removed Chrome). - Stable summary jobs (`test-fma-pr-only`, `test-fma`) aggregate the dynamic matrix results so branch protection / PR gating keeps a fixed check name. **Windows arch routing:** - Each changed `<name>/windows` slug's `installer_arch` is read from `ee/maintained-apps/inputs/winget/<name>.json`: `arm64` apps → `windows-11-arm`, x64/x86/neutral apps → `windows-latest` (x64). Missing input files default to x64 with a warning. This fixes installers that check the native OS architecture and abort under Prism emulation on the ARM runner (Inno Setup `ArchitecturesAllowed=x64` — GOG Galaxy, Reqable — and Docker Desktop). Future arm64 FMAs need no workflow change — `installer_arch: arm64` in the winget input is enough. - macOS needs no arch matrix: `macos-latest` is arm64 and x86-only casks run under Rosetta 2, which matches how customer Macs run them. # Checklist for submitter - [x] Input data is properly validated, `SELECT *` is avoided, SQL injection is prevented (using placeholders for values in statements), JS inline code is prevented especially for url redirects, and untrusted data interpolated into shell scripts/commands is validated against shell metacharacters. ## Testing - [x] QA'd all new/changed functionality manually Manual QA: - Partition script is shellcheck-clean and tested against the real repo for both platforms: empty input, mixed-platform slug lists, x86/neutral routing to the x64 runner, single-slug arrays, missing input file fallback, arm64/x64 split with sharding (via a synthetic arm64 input), invalid platform/shard-size rejection, and full-catalog partitions (384 Windows apps → 20 shards, 961 darwin apps → 39 shards, all slugs accounted for, matrix outputs well under the 1 MB job-output limit). - All six workflows pass `actionlint` and zizmor 1.25.2 (with the repo's `.github/zizmor-gate.yml` config) with no findings. - The rewritten Windows PR gate ran on this PR itself: the Linux detect job correctly found no changed Windows apps, skipped the Windows runners, and the `test-fma-pr-only` summary check passed. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added sharded validation for maintained macOS and Windows apps to run tests in parallel. * Added configurable `shard_size` for manual validation runs. * Introduced reusable validation workflows for Darwin and Windows. * Improved Windows testing to be architecture-aware (ARM64 vs x64). * **Bug Fixes** * Improved pull request gating to validate only changed apps and report results more reliably. * Workflows now gracefully handle scenarios where no matching apps are found (avoid unnecessary failures). <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>

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
- Containers (kube, etc)
- Linux-based IoT devices
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.
Fleet Device Management's company handbook is public and open source. You can read about the history of Fleet and our commitment to improving the product.
Chat
The Fleet community is full of kind and helpful people. Whether or not you are a paying customer, if you need help, just reach out.
Contributing
Contributions are welcome, whether you answer questions on Slack / GitHub / LinkedIn, improve the documentation or website, write a tutorial, give a talk at a conference or local meetup, give an interview on a podcast, troubleshoot reported issues, or submit a patch. The Fleet code of conduct is on GitHub.
License
The free version of Fleet is available under the MIT license. The commercial license is also designed to allow contributions to paid features for users whose employment agreements allow them to contribute to open source projects. (See LICENSE.md for details.)
