OpenCommit is a CLI tool that generates git commit messages using large language models.
The tool solves the problem of writing meaningful commit messages by automatically generating them based on staged changes. It works by sending the diff of staged files to an LLM provider, which returns a descriptive commit message that can be applied immediately. The approach is designed for speed, completing the process in approximately one second. The tool supports multiple LLM providers including OpenAI's GPT models, Anthropic's Claude, and other compatible services. It also supports running local models through Ollama or llama.cpp, allowing developers to generate commits without relying on external APIs.
Developers should choose this tool if they want to eliminate manual commit message writing while maintaining meaningful version control history. It suits any project using git where developers stage changes regularly. The tool is highly configurable, with options to customize emoji usage, commit message length, and other formatting preferences. For teams evaluating alternatives, the README does not name competing tools, so no comparison is available from the project's own documentation.
The project maintains an active development pace with regular updates addressing user issues and feature requests. The tool includes comprehensive documentation covering multiple setup scenarios, from cloud-based API providers to local model execution, indicating attention to diverse user environments and use cases.
