Commit Check (aka cchk) is an open-source tool that enforces commit metadata standards — including commit messages, branch naming, committer name/email, commit signoff, and more — to ensure consistency and compliance across teams.

As an alternative to GitHub Enterprise Metadata restrictions and Bitbucket's paid plugin Yet Another Commit Checker, Commit Check stands out by integrating DevOps principles and Infrastructure as Code (IaC) practices.

Version 2.0.0 is a major release featuring a new configuration format, a modernized architecture, and an improved user experience.

✨ Highlights

• TOML Configuration — Replaces .commit-check.yml with cchk.toml or commit-check.toml for clearer, more consistent syntax.
• Simplified CLI & Hooks — Legacy pre-commit hooks and options removed to deliver a cleaner, more streamlined interface.
• New Validation Engine — Fully redesigned for greater flexibility, performance, and maintainability.

To install Commit Check, you can use pip:

pip install commit-check

Or install directly from the GitHub repository:

pip install git+https://github.com/commit-check/commit-check.git@main

Then, run commit-check --help or cchk --help (alias for commit-check) from the command line. For more information, see the docs.

• Commit Check uses a default configuration if you do not provide a cchk.toml or commit-check.toml file.
• The default configuration is lenient — it only checks whether commit messages follow the Conventional Commits specification and branch names follow the Conventional Branch convention.

To customize the behavior, create a configuration file named cchk.toml or commit-check.toml in your repository's root directory, e.g., cchk.toml

For detailed usage instructions including pre-commit hooks, CLI commands, and STDIN examples, see the Usage Examples documentation.
