Who uses psutil

psutil is among the top 100 most-downloaded packages on PyPI, with 280+ million downloads per month and 790,000+ GitHub repositories using it. The projects below are a sample of notable software that uses it. They are grouped by how much of the project depends on psutil, and every usage links to the code that calls psutil.

Datadog

Agent checks read processes, disks and network through psutil.

Ray

Ships psutil in its own wheel; OOM monitor, process watcher, autoscaler.

Home Assistant

CPU, memory and disk for the system monitor integration.

OpenTelemetry

Its system-metrics instrumentation, which is how Splunk and Honeycomb users get psutil.

Built on psutil

psutil is a core dependency of these projects and central to how they work.

Project	Description	What it uses psutil for
Ray	Distributed runtime for AI and Python workloads	bundled inside the wheel; OOM monitor, process watcher, autoscaler, dashboard
Glances	System monitoring tool (top/htop alternative)	CPU, memory, disk, network, sensors, processes
Salt	Infrastructure automation at scale	master, minion, the ps execution module, beacons, grains
bpytop	Terminal resource monitor	CPU, memory, disk, network, processes
auto-cpufreq	CPU speed and power optimizer for Linux	CPU load and frequency readings
s-tui	Terminal CPU stress and monitoring utility	CPU, frequency and temperature readings
GRR	Remote live forensics by Google	client actions for processes, network connections and memory
psdash	Web dashboard using psutil and Flask	CPU, memory, disk, network, users, processes

Used for a specific feature

In these, psutil backs a single feature rather than the whole project.

Home Assistant	Home automation platform	the system monitor integration
Ansible	IT automation platform	counting active connections in the wait_for module
Apache Airflow	Workflow orchestration platform	task subprocess lifecycle
Sentry	Error tracking and performance monitoring	telemetry metrics
Celery	Distributed task queue	memory sampling used to debug leaks

Locust	Scalable load testing in Python	monitoring its own process
Dask	Parallel computing with task scheduling	worker memory management in distributed
Accelerate	Distributed training and inference launcher	physical CPU count, available memory, process launching
Spyder	Scientific Python IDE	memory usage in the status bar
Ajenti	Web-based server administration panel	dashboard widgets for CPU, memory, uptime and traffic
asitop	Apple Silicon performance monitoring CLI	memory and swap readings
integrations-core	Integration checks for the Datadog agent	15 check modules, including process, disk and network
Elastic APM	Application performance monitoring agent	CPU and memory metrics on Windows and macOS (its own /proc parser on Linux)

Used in development only

psutil is a test dependency only. Users of these projects never install it.

Project	Description	What it uses psutil for
TensorFlow	Machine learning framework by Google	unit tests
PyTorch	Deep learning framework with GPU acceleration	benchmark scripts

How this list was compiled

Candidates came from the GitHub dependency graph and from code search. Each one was then checked against the project’s packaging metadata and source, to make sure psutil is a real dependency and not just a mention. The links in the last column point at the code doing the work, pinned to a commit so the line numbers keep matching.
