See what your computer is actually doing.

A fast, native system monitor and task manager for Windows. Free and open source under the MIT licence. Watch it from your phone, scrape it with Prometheus, script it from a terminal.

What it does

Section titled “What it does”

Honest numbers

A reading the hardware cannot report is shown as unknown, never as zero. A feature your privileges do not allow is greyed out with the reason, not a button that fails when clicked.

Why is my PC slow?

One click correlates CPU, disk, memory pressure, network and thermal throttling, then names the cause in plain language: a verdict, the culprits and a minute of chart you can copy into a bug report.

Processes with a risk model

Grouped, searchable and steady under the pointer. End, suspend and resume state the actual consequence before you confirm, and processes that live for under a second are still recorded.

Performance, all of it

CPU with a cell per logical processor, memory, GPU, every disk and network adapter, and a Thermals tab that also lists what it cannot measure and why.

Beyond the window

Your phone over the LAN, Prometheus, Home Assistant, a typed TypeScript SDK and a CLI, all fed by one sampler so they always agree.

Light on your machine

The Windows sampler has a 30 ms-per-sample budget enforced in CI — at most about 3 % of one core at the one-second rate while visible — and it samples only every 20 seconds when hidden. A monitor that shows up as a top consumer in its own process list has failed at its job.

No telemetry

No analytics, no crash reporting, no account. The only automatic request is an update check, and you can turn that off.

Open source

MIT licensed. Every release carries a build attestation linking the installer to the exact commit and workflow that produced it.

Install

Section titled “Install”

Get Vitals: System Monitor from the Microsoft Store. There is no SmartScreen warning and the Store keeps it up to date. The Store build leaves out the built-in updater, the Task Manager replacement and the optional sensors service.

Phone, watch and TV

Section titled “Phone, watch and TV”

Every GitHub release carries three Android APKs: Vitals_<version>_android.apk for phones, _wear.apk for Wear OS and _tv.apk for Android and Google TV. Each monitors the device it runs on and can watch paired Windows PCs on your local network. Google Play listings are coming later.
