GitNexus Turns Any GitHub Repo Into an In-Browser Interactive Knowledge Graph, Fully Open-Source

A developer released GitNexus, an open-source tool that converts any GitHub repo (via URL or ZIP upload) into an interactive knowledge graph with AI chat.
It runs a 4-pass analysis: Pass 1 maps the full file structure; Pass 2 parses every file into ASTs with Tree-sitter; Pass 3 resolves imports and dependencies; Pass 4 builds the complete function call graph — then renders an interactive visual graph.
You can ask questions like "How does authentication work?", "What calls this function?", or "Show classes inheriting from BaseClass". Notably, everything runs in the browser: no backend, no server-side API calls, API keys stored locally, code never leaves the machine — zero cost, 100% open source.
