nornir
Pluggable multi-threaded framework with inventory management to help operate collections of devices
Decision gist · record as of 2026-08-14
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.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or higher; you must provide a config file (typically YAML) to define your inventory and settings.
- 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.

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.
