Repomix is a command-line tool that packs an entire repository into a single AI-friendly file for use with large language models.
The tool solves the problem of efficiently preparing codebases for consumption by LLMs and AI systems. It works by aggregating repository contents into a structured output file while respecting version control ignore patterns and security constraints. The approach includes token counting to help users stay within LLM context limits, code compression using Tree-sitter to reduce token overhead while maintaining structural integrity, and integration with Secretlint to automatically exclude files matching known credential formats.
Developers should choose this tool when they need to share their codebase with AI assistants or feed code to language models for analysis, generation, or review tasks. It suits projects of any size where understanding the full codebase context is valuable. The tool is available both as a command-line utility and through a web interface, making it accessible whether you prefer local installation or browser-based usage. Configuration is straightforward through command-line options and ignore files, allowing teams to customize what gets included in the output.
The project maintains active engagement with its user community through a dedicated Discord server for support and feature discussion. Development incorporates security as a core concern, integrating credential detection to prevent accidental exposure of sensitive data. The tool receives recognition within the open source ecosystem, having been nominated for awards in the AI-powered tools category.
