nornir

What it is and what it does

Nornir is a Python automation framework designed for managing and operating collections of network devices. Unlike traditional automation tools that use domain-specific languages, Nornir lets you write all automation logic directly in Python, making it easier to debug and leverage existing Python tooling. The framework handles inventory management, multi-threaded task dispatch, and provides a plugin architecture so you can extend it with custom tasks and integrations.

Since version 3.0.0, Nornir ships without built-in plugins; instead, you install plugins separately via pip as needed. It depends only on ruamel-yaml for configuration parsing and supports Python 3.10 through 3.14. The framework is actively maintained, with recent releases and an active community on GitHub and Discord.

Use it for:

• Automate configuration deployment across a fleet of network devices by writing Python scripts that iterate over your inventory.
• Gather operational data (show commands, metrics) from multiple devices in parallel and process results in Python.
• Build custom network validation or compliance checks by combining Nornir tasks with your own Python logic.
• Integrate network automation into larger Python applications or CI/CD pipelines without learning a new DSL.
• Troubleshoot automation failures using standard Python debugging tools (pdb, logging) instead of framework-specific diagnostics.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Nornir is a pure Python automation framework that manages device inventory and dispatches tasks across network nodes, letting you write automation logic directly in Python rather than a domain-specific language.

Yes. Nornir is actively maintained, has low install friction, carries a permissive Apache-2.0 license, and is well-suited for teams comfortable with Python who want to avoid a domain-specific language. The framework is mature (since 2018) and has a growing plugin ecosystem. Install it if you need to automate network device operations and prefer writing Python over learning a DSL.

Install

nornir on PyPI

pip install nornir

uv add nornir

poetry add nornir

Installing nornir

Before you install

Low install friction; pure Python wheel with a single runtime dependency on ruamel-yaml. Actively maintained with a recent release (12 days old) and steady commit activity.

License in practice

Apache-2.0 permissive license allows commercial and private use with minimal restrictions; you may use, modify, and distribute Nornir freely provided you include the license notice.

Quickstart

pip install nornir

from nornir import InitNornir

nr = InitNornir(config_file="config.yaml")
results = nr.run(task=your_task_function)

Requires Python 3.10 or higher; you must provide a config file (typically YAML) to define your inventory and settings.

Verify before relying

• Whether the plugin ecosystem is sufficiently mature and stable for your use case (documentation references a community plugin list but stability varies).
• Performance characteristics under large-scale deployments (fact sheet does not quantify typical device counts or task throughput).
• Integration requirements with existing network management or monitoring tools in your environment.
