How to Install RagApp on Ubuntu 24.04

RagApp is an open-source, Docker-deployable RAG (Retrieval-Augmented Generation) platform built with LlamaIndex. As simple to configure as OpenAI’s custom GPTs, but fully self-hosted in your own infrastructure. It provides an Admin UI for configuration, a Chat UI for end users, and a REST API for programmatic access. Built with TypeScript and Python, RagApp supports hosted AI models from OpenAI and Gemini, as well as local models via Ollama. Deployable via Docker Compose with one-command setup — ideal for enterprises that need private, customizable RAG without vendor lock-in.
