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

Under 1% CPU at idle, enforced by a budget test in CI. 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”

Download Vitals_x64-setup.exe and run it. There is no wizard; it installs in about five seconds. Windows SmartScreen will warn you on first run because the builds are not signed with a commercial certificate. The download page explains why and how to verify the file yourself.
