Deploy R2R in one click installation.
Production-ready RAG framework with hybrid search, knowledge graphs, and an agentic retrieval API for AI applications.
What you can build with R2R
R2R is an open-source retrieval-augmented generation framework built for production deployment from day one. It combines hybrid semantic and keyword search with reciprocal rank fusion, automatic knowledge graph construction, multimodal document ingestion, and an agentic retrieval API that lets large language models orchestrate search as part of their reasoning loop.
Self-hosting R2R on your own VPS keeps documents, vector indexes, and conversation history under your full control, with no per-query fees and no third-party access to your knowledge base. This deployment pairs the R2R API with the official dashboard and a PostgreSQL plus pgvector store, giving you a complete RAG stack you can extend with any LLM provider.
Key features of R2R
Hybrid search
Combine vector similarity and full-text keyword search with reciprocal rank fusion to surface the most relevant context for every query.
Knowledge graphs
Automatic entity and relationship extraction builds a graph index alongside vectors, enabling cross-document reasoning that flat retrieval cannot match.
Multimodal ingestion
Parse PDFs, Word documents, spreadsheets, images, and audio into a unified index without writing custom ingestion code for each format.
Agentic RAG
Reasoning agents iteratively retrieve, critique, and refine answers — producing higher-quality responses than single-shot RAG pipelines.
Multi-provider LLMs
Connect OpenAI, Anthropic, Google, Azure, Ollama, and 20-plus other LLM providers through a single configuration — no reindexing required.
REST API and SDKs
A full REST API plus official Python and JavaScript SDKs let you embed R2R retrieval into custom applications and automated pipelines.

I'm incredibly happy with Hostinger's VPS hosting! Their uptime is consistently top-notch, keeping my site running smoothly. Whenever I've needed help, their technical support team has been quick, knowledgeable, and genuinely helpful.
Everything is smooth and great with Hostinger, the AI chat bot + human chat, if AI can't resolve your question. Oh and them VPS is just fire, no ups and downs. Thank you dev team and everyone else involved. Keep it up 🚀
Finally a VPS hosting company that does it right! Well-priced. Excellent portal that respects their users' time. Seamless backups. Good support. Reliable. Feels rock-solid.
I reached out to Hostinger support after losing access to my self-hosted n8n instance, and I couldn’t be more impressed. Hostinger Agent and Mohammad from the support team were incredibly patient and thorough.
Many thanks to Carla for helping me with this N8N upgrade on my Hostinger VPS. Professional and knowledgeable, thank you again Carla.
Hostinger VPS is absolutely outstanding. It just always works. It is always fast and stable. Never down, never crashes.
The company is doing well, I am very happy with the specific services I use through them. Not as expensive as some places with really great VPS set ups and price plans.
