Halo is a Python library that renders beautiful animated spinners in the terminal, IPython, and Jupyter notebooks to indicate ongoing work. It supports context managers, decorators, customizable spinner frames, colors, text animations, and async support.

Use cases

• show a loading spinner while a long-running task executes in a CLI
• add a busy indicator to a Jupyter notebook cell
• wrap a slow function with a spinner using a decorator
• display progress feedback during API calls or downloads in Python scripts
• customize spinner frames, colors, and text animation in terminal apps

When to choose

• you need a polished terminal spinner in Python with minimal setup
• you want spinner support in IPython or Jupyter environments
• you prefer decorator or context-manager usage for long-running functions

When to avoid

• you need full progress bars rather than spinners (use tqdm or rich)
• you are building non-Python CLI tools
• you need a library under very active development
