Onboard-CLI: LLM‑Powered, AST‑Based CLI Tool for Codebase Visualization

A new command‑line utility named Onboard-CLI was announced on Show HN. The tool leverages large language models to interpret source code. It also parses abstract syntax trees to map project structure. Onboard-CLI generates visual representations of a codebase’s architecture. Users can run the utility directly from the terminal without a GUI. The approach aims to help developers understand unfamiliar projects quickly. The repository is hosted on GitHub and includes installation instructions. Early feedback suggests the visualization assists in onboarding and code reviews.
