description	Build self-contained Python executables using uv script metadata.

uv scripts

Create standalone Python scripts with inline dependency management using PEP 723 script metadata.

Bootstrap template

#!/usr/bin/env -S uv run --script
# /// script
# requires-python = ">=3.12"
# dependencies = [
#     "typer",
#     "rich",
# ]
# ///
"""Script description."""

def main() -> None:
    pass

if __name__ == "__main__":
    main()

Make executable

chmod +x bin/my-script.py

Run

./bin/my-script.py
# or
uv run --script bin/my-script.py

Script metadata format

The # /// script block declares dependencies inline:

# /// script
# requires-python = ">=3.12"
# dependencies = [
#     "requests>=2.28",
#     "pydantic",
# ]
# ///

Local package dependencies

Reference local packages with [tool.uv.sources]:

# /// script
# requires-python = ">=3.12"
# dependencies = [
#     "my-local-package",
#     "rich",
# ]
#
# [tool.uv.sources]
# my-local-package = { path = "..", editable = true }
# ///

Add dependencies

Use uv add --script to add dependencies to an existing script:

uv add --script bin/my-script.py httpx rich

Common dependencies

• CLI: typer, click
• Output: rich
• HTTP: httpx, requests
• Data: pydantic, polars, pandas
• YAML: pyyaml, ruamel.yaml
