Repomix is an open-source CLI tool that flattens an entire codebase — respecting .gitignore, optionally stripping comments, counting tokens — into one clean, structured file optimized for pasting into an LLM's context window. It supports Claude, ChatGPT, DeepSeek, Perplexity, Gemini, Gemma, Llama, Grok and more, and is popular for code review, refactoring, and documentation-generation workflows. MIT-licensed with 27,000+ GitHub stars.
