Chatchat Lite is an open-source, lightweight chat UI framework designed to run in the browser and connect to multiple AI backends—including OpenAI, Azure, custom HTTP endpoints, and local language models. It provides real-time streaming responses, Markdown rendering, code block formatting, theme toggles, and persistent conversation history. Developers can extend it with custom plugins, environment-based configurations, and adaptability for self-hosted or third-party AI services, making it ideal for prototypes, demos, and production chat apps.

RAGApp is designed to simplify the entire RAG pipeline by providing out-of-the-box integrations with popular vector databases (FAISS, Pinecone, Chroma, Qdrant) and large language models (OpenAI, Anthropic, Hugging Face). It includes data ingestion tools to convert documents into embeddings, context-aware retrieval mechanisms for precise knowledge selection, and a built-in chat UI or REST API server for deployment. Developers can easily extend or replace any component—add custom preprocessors, integrate external APIs as tools, or swap LLM providers—while leveraging Docker and CLI tooling for rapid prototyping and production deployment.
