pyodide-cli
"The command line interface for the Pyodide project"
Decision gist · record as of 2026-08-14
Yes, if you are developing tools for the Pyodide ecosystem or need to register subcommands in the Pyodide CLI. The package is actively maintained, has low install friction, and is designed to be a dependency of other ecosystem packages rather than a standalone tool. Direct installation is typically unnecessary unless you are extending Pyodide's CLI.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.12 or later.
- Low install friction with only two lightweight runtime dependencies (click and rich).
- Actively maintained with recent releases; the repository is current and well-established within the Pyodide ecosystem.

What it is and what it does
pyodide-cli is the command-line interface layer for the Pyodide project, built on click and rich for command handling and terminal output. It serves primarily as a plugin host: other packages in the Pyodide ecosystem (such as pyodide-build, pyodide-pack, and auditwheel-emscripten) depend on it and register their own subcommands via setuptools entry points, allowing them to extend the main `pyodide` command without modifying this package directly.
Developers building tools for the Pyodide ecosystem use pyodide-cli as a foundation by adding a dependency on it and registering a `pyodide.cli` entry point that points to a click command or typer app. The package handles command discovery and dispatch, so each tool can contribute its own subcommand to a unified CLI interface.
Use it for
- Extending the Pyodide CLI with custom subcommands from your own package via entry points
- Building Pyodide ecosystem tools that integrate with the main `pyodide` command
- Centralizing CLI infrastructure for related Pyodide build and packaging tools
- Registering click or typer-based commands that appear under the main `pyodide` namespace
