Building RagRabbit, An Open Source RAG Search with Postgres as the Vector Store

RagRabbit is an open-source toolkit for Retrieval-Augmented Generation (RAG) that uses Postgres for all functions. It crawls websites, converts pages to Markdown, generates embeddings, and provides AI Q&A using OpenAI or Claude. The tool offers features like automatic site crawling, LLM-friendly text output, and an MCP server for integration with IDEs. RagRabbit can be deployed on Vercel with Neon as the Postgres host, providing a serverless setup with easy scaling and cost management.
