Deploy and Host n8n on Railway

n8n is an extendable, fair-code workflow automation tool that lets you connect any app with an API to any other app and manipulate its data with little or no code. Its visual, node-based editor makes it highly versatile, while self-hosting keeps your workflows and credentials private and under your control.

About Hosting n8n

Hosting n8n means running its Node.js application server, persisting workflows and credentials in a database, and serving the visual editor plus webhook endpoints over HTTPS. A production deployment goes further: n8n's queue mode separates the main process (editor, API, webhook intake, scheduling) from one or more worker processes that execute workflows, using Redis as the job broker and PostgreSQL as the shared system of record. On Railway, this maps cleanly onto four services — n8n main, n8n worker, Postgres, and Redis — connected over the private network, with a persistent volume for n8n's data directory and a single public domain for the editor and webhooks.

Common Use Cases

• Building automations and integrations between 400+ apps and APIs without writing glue code
• Self-hosting AI agent workflows and LLM orchestration pipelines with full data privacy
• Receiving and processing webhooks from third-party services at a stable public URL

Dependencies for n8n Hosting

• PostgreSQL — stores workflows, credentials, executions, and settings
• Redis — Bull queue broker that coordinates queue-mode executions

Deployment Dependencies

• n8n self-hosting documentation: https://docs.n8n.io/hosting/
• n8n queue mode documentation: https://docs.n8n.io/hosting/scaling/queue-mode/
• n8n environment variable reference: https://docs.n8n.io/hosting/configuration/environment-variables/

Implementation Details

This template deploys four services: n8n (main process — editor, REST API, webhook intake, and scheduling — with a public domain, /healthz health check, and a persistent volume at /home/node/.n8n), n8n-worker (same image, dedicated queue-mode execution worker), Postgres (with volume), and Redis (with volume). Queue mode (EXECUTIONS_MODE=queue) is enabled on both n8n services; the worker shares the main service's generated N8N_ENCRYPTION_KEY via a cross-service reference, and all database and queue connections use private-network references.
