DeepResearcher — multi-agent research with LangGraph

DeepResearcher is my open-source personal research application, built with LangGraph, Python/FastAPI and React/TypeScript. A scope agent clarifies the question, a supervisor coordinates parallel research, findings are compressed and a writer produces a Markdown report with sources. The web interface streams progress over WebSocket. It supports configurable models and user-provided API keys without persisting those keys. Docker is used for deployment. This is a personal project, not client work.
