RAG Central is a RAG AI chatbot boiler plate. It is a fully functioning self contained website that is fast and lean. It's built using NodeJS, Express, Socket.IO and PassportJS and it uses PostgreSQL with vector add ons for storing vector embeddings. It connects to OpenAI and has Stripe integration (you will need to provide your own API keys to use these features.) RAG Central was built on and designed to run on a low cost / low spec Ubuntu Linux server hosted locally or a hosted VPS.
