NetBox

Project21.7K

Model intended network infrastructure as a source of truth for automation and operations.

What you can build

  • Build a UI-run custom script that takes branch details as input and automates the corresponding NetBox provisioning tasks, producing modeled records for the new site.
  • Create Jinja2 templates that turn a selected device’s NetBox data into a configuration file, then retrieve the rendered output through the REST API for a provisioning tool.
  • Write a custom validation rule that rejects deletion of devices marked active, using the README’s stated validation and deletion-protection workflow.
  • Build a receiver for NetBox outbound webhooks that transforms a new-device or IP-range-allocation event into the payload format required by an internal operations system.
  • Build a plugin with a new handoff model and view that takes circuit and endpoint details as input and records a reviewable circuit-turn-up handoff in NetBox.

Try this prompt

Build a small end-to-end NetBox custom script for branch-office provisioning. Ask the operator for the branch’s identifying details, validate the input, and create the corresponding modeled records using NetBox’s supported script workflow. Show a clear result or validation errors, avoid destructive changes, and preserve existing records. Follow the project’s official documentation for the supported script interface; do not invent APIs or assume the script configures network devices.

Get started

  1. Follow the official installation documentation

    Start at https://docs.netbox.dev for the official introduction and installation guidance; use the instructions appropriate to the NetBox version you plan to run.

  2. Model your network

    Begin with NetBox’s native network objects, such as devices, IP addresses, cables, and circuits. Add custom fields and tags where your workflow needs additional attributes.

  3. Choose an extension point

    Use the documented REST API, custom scripts, Jinja2 templates, event rules, or plugin framework for your adaptation; the README links to the full documentation at https://docs.netbox.dev.

License & notes

Apache-2.0Apache-2.0 permits commercial use. If you redistribute the software or modified versions, comply with the license, including providing the license and marking modified files. Self-hosting requires compute, hosting, and operational resources; their costs depend on your deployment. NetBox Cloud and Enterprise are separate offerings; their terms and costs are not specified here. No model or paid-API requirement is documented for the core application.

  • NetBox models intended network state; it does not discover, monitor, or configure network nodes.
  • Rendered device configurations must be retrieved and applied by a separate provisioning tool.
  • Self-hosted deployments require infrastructure and ongoing operations; deployment costs depend on your environment.
