pynetbox vs netbox-sdk

Side-by-side comparison of two Python libraries for the NetBox REST API.

pynetbox is the official Python client for the NetBox REST API, maintained by the netbox-community organization. It has been the go-to choice since 2017 — originally authored at DigitalOcean — and is the de facto standard for scripting against NetBox in Python.

netbox-sdk is a newer library (2024, pre-release) built on an async runtime from the start. It ships a standalone SDK, an OpenAPI-driven CLI, and a Textual TUI inside a single package, and includes a local mock server for testing without a live NetBox instance.

Both libraries talk to the same NetBox REST API. The right choice depends on whether your workflow is script-oriented and synchronous, or service-oriented and async. The sections below compare the two without exaggeration.

›libraries

emerson@netdevops:~/netbox-sdk$ cat libraries.md

pynetbox

A thin, synchronous Python wrapper around the NetBox REST API. Returns Record and RecordSet objects with ORM-like attribute access, .save(), and .delete() methods — so you can write device.name = 'foo'; device.save() without building a dict manually.

pynetbox is sync-only (built on requests). It supports parallel pagination via threading=True, strict OpenAPI-backed filter validation, and a context manager for the NetBox branching plugin. No mock server is bundled — you stub requests with unittest.mock in tests.

The library is maintained by the netbox-community GitHub organization and follows NetBox releases closely. NetBox compatibility is documented in a version matrix from 3.3 through 4.5.

best for

  • ›Scripts, Ansible playbooks, and automation that already use the NetBox community ecosystem
  • ›Projects that prefer ORM-style .save()/.delete() over explicit API calls
  • ›Environments requiring minimal runtime dependencies in production
  • ›Workflows using the NetBox branching plugin via activate_branch()

netbox-sdk

An async SDK built on aiohttp, exposing three usage layers: a raw HTTP client, an async facade (api()), and a versioned typed client (typed_api()) that returns Pydantic models for NetBox 4.3–4.6. All three share the same runtime.

The package ships optional extras: [cli] adds a Typer-based nbx CLI with OpenAPI-driven dynamic commands, [tui] adds a Textual-based terminal interface, and [mock] adds a local FastAPI mock server (nbx-mock) so you can develop and test without a live NetBox instance.

netbox-sdk is pre-release (alpha, version 0.0.9) with low adoption. The API surface covers NetBox 4.3–4.6 and may change between releases. Python 3.11+ is required.

best for

  • ›Async applications and services that need native asyncio support
  • ›Developing or testing locally without a live NetBox instance (mock server)
  • ›Projects that want full type safety with Pydantic-validated NetBox responses
  • ›Workflows that benefit from a ready-made CLI (nbx) or TUI for NetBox operations

›when to choose

emerson@netdevops:~/netbox-sdk$ ./recommend.sh

use pynetbox when

  • ›Scripts, Ansible playbooks, and automation that already use the NetBox community ecosystem
  • ›Projects that prefer ORM-style .save()/.delete() over explicit API calls
  • ›Environments requiring minimal runtime dependencies in production
  • ›Workflows using the NetBox branching plugin via activate_branch()

use netbox-sdk when

  • ›Async applications and services that need native asyncio support
  • ›Developing or testing locally without a live NetBox instance (mock server)
  • ›Projects that want full type safety with Pydantic-validated NetBox responses
  • ›Workflows that benefit from a ready-made CLI (nbx) or TUI for NetBox operations

If you are writing scripts, Ansible playbooks, or any synchronous automation against NetBox today, pynetbox is the right choice. It is battle-tested since 2017, follows the NetBox release cadence, has minimal dependencies, and is maintained by the netbox-community organization.

If you are building an async service or application that talks to NetBox, or if you need to develop and test locally without a live instance, netbox-sdk is worth evaluating. Its aiohttp runtime, Pydantic-typed responses, mock server, and optional CLI/TUI serve a different workflow than pynetbox.

The two libraries are not in competition for the same use case. pynetbox targets scripting and synchronous automation; netbox-sdk targets async services and teams that want typed models, a development mock, or a terminal interface.
