Overview

What is RAG AI Backend?

A backend framework designed to power Retrieval-Augmented Generation (RAG) applications, enabling developers to build AI-driven apps that retrieve and generate content efficiently. It is particularly useful for teams looking to integrate RAG capabilities into their existing systems without the need for extensive setup or maintenance.

Key differentiator

“The only RAG framework offering a self-hosted solution for efficient retrieval-augmented generation, tailored specifically for JavaScript/TypeScript ecosystems.”
