opencommit and CodeGPT
These are direct competitors offering similar functionality—both generate git commit messages via LLM through CLI tools—though opencommit has broader LLM provider support while CodeGPT is specialized for OpenAI models.
About opencommit
di-sukharev/opencommit
top #1 and most feature rich GPT wrapper for git — generate commit messages with an LLM in 1 sec — works with Claude, GPT and every other provider, supports local Ollama models too
Supports multiple LLM providers and models via provider-agnostic configuration (OpenAI, Anthropic, Azure, Ollama, Gemini, Deepseek, etc.) with caching and dynamic model discovery. Analyzes staged git diffs and generates commit messages following configurable templates—conventional commits or commitlint standards—with optional GitMoji prefixes, extended descriptions, and per-repository or global `.env`/config file settings. Integrates as a global npm CLI tool (`oco` command) that works with any git workflow, including local Ollama inference for air-gapped environments.
About CodeGPT
appleboy/CodeGPT
A CLI written in Go language that writes git commit messages or do a code review brief for you using ChatGPT AI (gpt-4.1, gpt-4o model) and automatically installs a git prepare-commit-msg hook.
Supports multiple LLM backends (Azure OpenAI, Gemini, Anthropic, Ollama, Groq, OpenRouter) with dynamic API key credential management and customizable prompt templates. Integrates deeply with Git workflows through prepare-commit-msg hooks while adhering to Conventional Commits specification, with additional features like streaming output, context-aware diffs, and multi-language commit message translation.
