Deploy and Host N8n Self Hosted AI Stack on Railway

N8n Self Hosted AI Stack is a private automation and AI platform. It includes n8n for workflows, Postgres for storage, Ollama for local models, and Qdrant for vector search. Your prompts, documents, and credentials stay inside your Railway project with no third party AI API required.

About Hosting N8n Self Hosted AI Stack

This template deploys four services already connected over Railway private networking. n8n stores workflows and credentials in Postgres, runs inference through Ollama, and uses Qdrant for embeddings and RAG. After deploy, open the n8n public URL, create your owner account, pull a model into Ollama, and start building. Ollama uses the most memory because it holds model weights. Postgres and Qdrant stay light for hobby and small team workloads.

Common Use Cases

• Private RAG chatbots that answer from your own documents
• AI agents in n8n that call local models instead of cloud APIs
• Internal automation with semantic search over company knowledge
