abhigyanpatwari/GitNexus

Everything runs inside the browser tab — no backend, no API keys wired to a server, no data leaving your machine. You point GitNexus at a public GitHub repository URL or upload a ZIP of any codebase, and it parses the files, builds a knowledge graph of how modules, functions, and dependencies relate to each other, and renders it as an interactive visual you can explore. On top of that graph sits a built-in Graph RAG agent you can query in plain language, so instead of grepping through folders you just ask which module handles authentication or where a particular function is called. The practical use case is onboarding fast. New contract, open-source audit, or a legacy repo you inherited — you get a structural map in minutes rather than hours. Because it is fully client-side, teams in regulated environments or anyone cautious about code privacy will appreciate the zero-egress approach. The honest reservation is that very large monorepos may hit browser memory limits, and the RAG quality will depend on how well the graph captures dynamic or loosely-typed code patterns. -> Best for: freelance developers and security-conscious engineering leads who need rapid structural orientation in unfamiliar codebases without standing up any tooling.
