CodeContexter – simple codebase serializer for LLM Context Windows

CodeContexter is a fast, safety-first CLI tool written in Rust. It aggregates your entire codebase into a single, structured file (Markdown, JSON, or XML).

It is designed specifically for providing context to Large Language Models (LLMs) like ChatGPT, Claude, and GitHub Copilot without manual copy-pasting.

CodeContexter:

• Walks your directory (respecting .gitignore).
• Generates a visual tree of your project structure.
• Aggregates file contents into a single formatted output.
• Redacts secrets automatically to keep your keys safe.

This is free and open source software.

Features include:

• Parallel processing (Rayon) and streaming output for low memory usage on huge repos.
• Security First: Automatically detects and redacts private keys, API tokens, and secrets before they leave your machine.
• Smart Filtering: Respects .gitignore, skips binary files, ignores whitespace-only files, and prevents symlink loops.
• Large File Handling: Smartly truncates files over 1MB (shows the first and last 50 lines) to preserve token limits while keeping context.
• Clipboard Ready: Optional flag to copy the output directly to your clipboard.
• Multiple Formats: Output to Markdown (default), JSON, or XML.
