Ragstack Lambda

Ragstack Lambda is an open-source, serverless platform for uploading, processing, and querying documents and media using retrieval-augmented generation (RAG). Designed for technical users, organizations, and developers, it leverages AWS services to extract and index text from a wide range of formats (e.g., PDFs, images, video, audio) and allows natural language querying with source attribution. It features a fully serverless architecture with a managed knowledge base, scalable to zero idle costs, and easy integration via web components or MCP for tools like Claude, VS Code, and more.
