## What it is
nbgrader is a system for creating, distributing, collecting, and grading Jupyter notebook assignments. It provides instructor toolbar and formgrader extensions, a student assignment list extension, and command line tools for the full assignment lifecycle.

## Use cases
- create and release Jupyter notebook assignments to students
- autograde notebook submissions with tests
- manually grade student notebooks with a grading UI
- let students fetch and submit assignments from Jupyter
- generate student versions of assignments from master notebooks
- manage course homework workflow via command line

## When to choose
- you teach courses using Jupyter notebooks and need automated grading
- you want an integrated assign/release/collect/grade workflow in Jupyter or JupyterHub
- you need both autograding and manual grading of code cells

## When to avoid
- you grade assignments that are not Jupyter notebooks
- you need a full LMS rather than a notebook grading tool
- you want plagiarism detection or proctoring features

## Facets
- artifact type: application

- function: cli, developer-tools
- domain: education, developer-tools, data-science
- platform: python, cross-platform
