Best for

Developers or AI engineers who need to format codebases into a single file for LLM input while tracking token counts and filtering out sensitive information.

Key capabilities

Formats your codebase to be easily understood and processed by AI, generating a single output file.
Calculates token counts for individual files and the entire repository to assist with LLM context limits.
Respects .gitignore, .ignore, and .repomixignore files to include or exclude files automatically.
Uses Secretlint to detect and prevent the inclusion of sensitive information during the packing process.
Uses Tree-sitter via the --compress option to extract key code elements, reducing token count while preserving structure.
Packs remote repositories directly without requiring a local clone.
Supports the Model Context Protocol, allowing AI assistants to interact directly with your codebase without manual file preparation.

Limitations and risks

The output file remains subject to LLM context window limits.

Getting started

Run instantly without installation using npx repomix@latest to pack a repository with a single command.
