cgen

cgen is a lightweight command-line utility for automatically generating git commit messages from your staged changes. It integrates with 17 built-in LLM providers including OpenAI, Anthropic, Groq, and local model servers, letting you review, edit, or regenerate messages before committing. The tool ships as a single 3 MB executable with no runtime dependencies.

Designed for developers who want to streamline commit workflows, cgen follows Conventional Commits by default and supports custom templates, multiple languages, and gitmoji formatting. It includes advanced features like commit history browsing, safe undo operations, semantic version tagging, and automatic fallback between configured LLM providers. The maker notes that portions of the core logic were built using agentic AI.
