How to Install LEANN on Hostinger VPS

LEANN is a lightweight vector database that turns any laptop into a private RAG engine. Using graph-based selective recomputation, it computes embeddings on demand instead of storing them, cutting storage by up to 97% without sacrificing accuracy. It ships with native MCP integration, works with LangChain, LlamaIndex, Ollama and Claude Code, and can index your files, emails, chat history and live data — fully offline.
