SystemPulse

Know what your computer is doing without leaving the terminal.

SystemPulse is an open-source, local, read-only system monitor. It shows live CPU, memory, process, and available GPU readings in a keyboard-driven terminal interface. It has no web dashboard, account, or telemetry. Sustained threshold rules produce factual observations and local alerts; doctor checks SystemPulse itself.

Development preview: 0.1.0.dev1. PyPI package. Install systempulse-monitor; run systempulse. Python 3.12+ is required.

Install and run

Install uv once:

Windows (PowerShell)

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

macOS or Linux

curl -LsSf https://astral.sh/uv/install.sh | sh

Open a new terminal, then install Python 3.12 with uv:

uv python install 3.12

Install the published preview and add uv's tool directory to your PATH:

uv tool install --python 3.12 "systempulse-monitor==0.1.0.dev1"
uv tool update-shell

Open a new terminal and run SystemPulse from any directory:

systempulse

The command opens the TUI in an interactive terminal. uv is only needed to install or update SystemPulse; daily use does not require uv run. No configuration or elevated permissions are needed for the default experience.

Already use pipx with Python 3.12+? Install with:

pipx install "systempulse-monitor==0.1.0.dev1"
systempulse

Use systempulse-monitor as the package name; systempulse on PyPI belongs to another project. If you previously installed this project from a checkout, add --reinstall to the uv install command to switch to the published package.

git clone https://github.com/jeiel2013/SystemPulse.git
cd SystemPulse
uv tool install --reinstall --python 3.12 .
uv tool update-shell

What you can see

• Overview: live CPU and RAM, home-volume disk usage, network transfer rates, a recent CPU chart, optional GPU load/VRAM/temperature, and separate Top CPU and Top RAM process lists. Disk and network rates need two samples.
• Processes: search, sort by CPU, memory, or PID, and open verified process details. Restricted fields appear as unavailable.
• System: operating system, uptime, CPU and memory information, every GPU reported by the active provider, and battery/sensor readings when available.
• History: local CPU, memory, disk, and network trends for 10 minutes through 30 days. The database stores metric summaries, not process names or commands.
• Alerts: local CPU, memory, and disk threshold rules require continuous evidence before triggering. Dismissed and resolved alerts remain visible.
• Process tree: an on-demand parent/child scan, separate from the faster periodic process table.
• Reports: export a single observed snapshot as JSON, CSV, Markdown, or a static HTML file.

GPU readings use installed nvidia-smi, rocm-smi, or xpu-smi tools. Without a supported source, SystemPulse marks GPU metrics unavailable. AMD and Intel providers still need validation on physical hardware. Battery and sensor availability depends on the host. See GPU collection and hardware sources.

Other commands

systempulse status
systempulse top --sort memory --limit 10
systempulse processes --sort memory --limit 10
systempulse processes --search python
systempulse history --range 1h
systempulse alerts
systempulse tree --limit 100
systempulse report --format json
systempulse plugins
systempulse doctor
systempulse version

status prints one system snapshot. top refreshes a compact process monitor every second; press q or Ctrl+C to leave it. It requires an interactive terminal. processes prints a filtered list. doctor checks the runtime, collectors, GPU provider, and terminal. The other commands exit after printing.

Keyboard shortcuts

SystemPulse adapts both themes to the terminal's reported color support. On Linux, systempulse doctor shows the detected color mode. If your terminal supports truecolor but reports fewer colors, run TEXTUAL_COLOR_SYSTEM=truecolor systempulse to use the full palette.

Current scope

The maintainer has tested the TUI and CLI on Windows and Linux. CI has passed tests, package builds, and isolated tool-install checks on Windows, Ubuntu, and macOS. Interactive macOS validation remains pending. See alerts and configuration, history storage and release checks. See reports for export formats and locations. Collector plugins are opt-in; see plugin development.

Typed collectors feed application state, then Textual and the CLI. Collection runs outside the UI loop. SystemPulse keeps metrics on the machine and does not perform destructive actions. See the runtime benchmark for measurements and current performance limits. The architecture and development guides explain the codebase.

Contribute

Run uv run pytest, uv run ruff check ., and uv run mypy before proposing changes. Code and canonical documentation are in English; public documentation also has a pt-BR version. When translations differ, the English version prevails.
