# Cleanmeter

> A free, open-source system monitor for Windows that displays real-time CPU, GPU
> and RAM stats as a clean, customizable overlay. Built by Team Crispy.

Cleanmeter is a lightweight overlay for Windows 10 and 11. It shows live hardware
metrics on top of whatever you are doing, and is designed to stay out of the way:
you pick which metrics appear, where they sit, and which hotkey toggles them.

It is free, has no paid tier, and the source is on GitHub.

## Key facts

- Platform: Windows 10 and 11, 64-bit. Linux support is planned; macOS is not.
- Price: free, open source.
- Metrics: CPU and GPU temperature and load, RAM usage, network, FPS and frametime.
- Overlay: horizontal or vertical, adjustable size and opacity, custom temperature
  ranges, several graph styles, light and dark themes.
- Sensors: you can select which specific CPU, GPU and network sensors to read.
- Pixel Shift: the overlay moves slightly over time to prevent static burn-in on
  OLED displays.
- Updates: the site pulls the current version from the GitHub releases API
  rather than hardcoding it.
- Known limitation: Cleanmeter does not currently work over fullscreen games. Use
  borderless windowed mode.
- Windows may warn that the installer is unrecognized. SmartScreen is a
  reputation check rather than a virus scan: it flags installers from publishers
  it has not seen enough of, and an unsigned build never accrues that reputation.
  Users can verify the installer's SHA-256 against the GitHub release page.
- Default overlay show/hide hotkey is Ctrl+Alt+F10, and it is rebindable.
- Updates are checked in the background and offered in the settings window; the
  user chooses when to download and when to install. Nothing installs silently.
- Kernel driver: PawnIO since v2.2.13, replacing WinRing0, which Defender flags
  and which cannot load with Memory Integrity or Secure Boot enabled.
