CodebaseChat

Onboarding to a new codebase is painful. Reading through docs, trying to understand the architecture, figuring out how things connect — it takes days, sometimes weeks. CodebaseChat is a free, open-source tool that shortcircuits that process. Provide a GitHub repository URL, and CodebaseChat crawls the repo, generates an index file, and creates a custom OpenAI GPT with knowledge of that entire codebase.

Once set up, you can ask natural language questions about the code — what does this function do, how does this module connect, where is this feature implemented — and get immediate, intelligent answers. It's the fastest way to get up to speed on any GitHub project, whether you're a new contributor, a technical reviewer, or just exploring an interesting open-source tool.
