Project description

PyPI licheck version PyPI - License Buy me a coffee pre-commit

Automatically check the licenses of package dependencies.


Inspired by kontrolilo, check the licenses of sotware dependencies in package managers used by developers. This program is primarly aimed to be used as a git hook with pre-commit.


Please read carefully the External programs section of the documentation to learn which programs you need to install before licheck.

Have a look at the Configuration file section to know how to configure licheck.

API examples

licheck has a public API. This means for example that you can you easily build a TOC within another Python program. The easiest way to build one for a markdown file is:

>>> import licheck
>>> f = open('Pipfile')
>>> print(, end='')
name = "pypi"
url = ""
verify_ssl = true

Sphinx = "~=4.1"

python_version = "*"
>>> binary, program = licheck.get_binary_and_program('python')
>>> command = licheck.build_command(binary, program, 'Pipfile')
>>> print(licheck.get_data(command, program))

CLI Helps
