This article introduces Codebase Navigator, a tool designed to simplify the process of understanding large, unfamiliar GitHub repositories. By pasting a repository URL, users can interact with an AI assistant that provides a live dependency graph built from actual import statements, a code viewer, and a full file tree. Unlike standard AI assistants that often hallucinate file paths, this tool uses real data to visualize connections between files in real time. Built with a modern tech stack including Next.js, CopilotKit, and React Flow, the project can be run entirely for free using local LLMs via Ollama. The author provides a deep dive into the architecture, the technical implementation of the dependency resolution, and how the tool maintains state across multiple UI panels.
Sage is a tool that allows developers to chat with any codebase using two commands. It provides a functional chat interface for code, supports running locally or on the cloud, and has a modular design for swapping components.
