DeepV-Ki is an AI-powered wiki generator for code repositories that combines a Next.js frontend with a FastAPI backend. The system allows users to input a repository URL and automatically generates documentation, architecture diagrams (Mermaid), and provides a RAG-based Q&A interface. It features multi-LLM provider support (OpenAI, Google Gemini, Azure, AWS Bedrock, Ollama), GitLab/GitHub/Bitbucket integration, asynchronous task processing with Celery, and multi-layer caching. The architecture follows a monorepo structure with clear separation between frontend (React/Next.js) and backend (Python/FastAPI) components, communicating via REST APIs. The system includes sophisticated authentication (SSO, session management), progress tracking, and real-time WebSocket communication for streaming AI responses.
