It is useful mainly for **system monitoring**, **profiling and limiting process resources** and **management of running processes**. It implements many functionalities offered by classic UNIX command line tools such as *ps, top, iotop, lsof, netstat, ifconfig, free* and others. psutil currently supports the following platforms: - **Linux** - **Windows** - **macOS** - **FreeBSD, OpenBSD**, **NetBSD** - **Sun Solaris** - **AIX** Supported Python versions are **2.6**, **2.7**, **3.4+** and `PyPy <http://pypy.org/>`__. Funding ======= While psutil is free software and will always be, the project would benefit immensely from some funding. Keeping up with bug reports and maintenance has become hardly sustainable for me alone in terms of time. If you're a company that's making significant use of psutil you can consider becoming a sponsor via `GitHub <https://github.com/sponsors/giampaolo>`__, `Open Collective <https://opencollective.com/psutil>`__ or `PayPal <https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=A9ZS7PKKRM3S8>`__ and have your logo displayed in here and psutil `doc <https://psutil.readthedocs.io>`__.
