Using commitizen cli



Commitizen is release management tool designed for teams.

Commitizen assumes your team uses a standard way of committing rules and from that foundation, it can bump your project's version, create the changelog, and update files.

By default, commitizen uses conventional commits, but you can build your own set of rules, and publish them.

Using a standardized set of rules to write commits, makes commits easier to read, and enforces writing descriptive commits.


  • Command-line utility to create commits with your rules. Defaults: Conventional commits
  • Bump version automatically using semantic versioning based on the commits. Read More
  • Generate a changelog using Keep a changelog
  • Update your project's version files automatically
  • Display information about your commit rules (commands: schema, example, info)
  • Create your own set of rules and publish them to pip. Read more on Customization


Python 3.8+



To make commitizen available in your system

pip install --user -U Commitizen

Python project

You can add it to your local project using one of these:

pip install -U commitizen

for Poetry >= 1.2.0:

poetry add commitizen --group dev

for Poetry < 1.2.0:

poetry add commitizen --dev


via homebrew:

brew install commitizen


Most of the time this is the only command you'll run:

cz bump

On top of that, you can use commitizen to assist you with the creation of commits:

cz commit

Read more in the section Getting Started.

    version             get the version of the installed commitizen or the current project (default: installed commitizen)

Setting up bash completion

When using bash as your shell (limited support for zsh, fish, and tcsh is available), Commitizen can use argcomplete for auto-completion. For this argcomplete needs to be enabled.

argcomplete is installed when you install Commitizen since it's a dependency.

If Commitizen is installed globally, global activation can be executed:

sudo activate-global-python-argcomplete

For permanent (but not global) Commitizen activation, use:

register-python-argcomplete cz >> ~/.bashrc

For one-time activation of argcomplete for Commitizen only, use:

eval "$(register-python-argcomplete cz)"

For further information on activation, please visit the argcomplete website.
