Nornir is a free, open-source Python automation framework for managing inventory and dispatching tasks to network nodes and devices. It is used directly from Python: inventories contain hosts, groups, and defaults, while reusable tasks accept a Task and return a Result. The included ThreadedRunner runs tasks across hosts with threads and defaults to 20 workers. Plugins cover inventories, transforms, connections, runners, and processors, with community integrations for NAPALM, Netmiko, NetBox, Ansible inventories, Scrapli, Nautobot, and other systems. Nornir supports configuration management, workflow orchestration, and network testing across platforms including Cisco IOS, Cisco NX-OS, Arista EOS, Junos, and Palo Alto PAN-OS. OpsMill describes parallel writes, idempotence, and dry-run safety. The package is published on PyPI and installs with pip; the current package requires Python 3.10 or later. It is self-hosted under Apache-2.0.
