Deploy and Host n8n on Railway

Self-host the open-source alternative to Zapier — unlimited executions, no per-task billing, full data ownership.

n8n is the world's most popular open-source workflow automation platform with 188k+ GitHub stars, 100M+ Docker pulls, and 500+ integrations. Build powerful automations visually, write code when you need it, and connect AI agents, APIs, and databases — all without execution caps or vendor lock-in.

What This Template Deploys

Service	Purpose
n8n	Workflow engine and visual editor, accessible at your Railway public URL on port `5678`
PostgreSQL	Managed Railway database — stores workflows, credentials, and execution history persistently

Both services connect over Railway's private network. PostgreSQL credentials are injected automatically — no manual configuration required.

Deploy in Under 5 Minutes

Click Deploy on Railway and wait for the build to complete (~2–3 minutes)
Railway provisions n8n + PostgreSQL automatically
Open your Railway URL — set your admin credentials on first launch
Start building workflows immediately

No SSH. No Docker Compose. No reverse proxy. No SSL certificates to manage.

Configuration

Variable	Required	Description
`DB_TYPE`	✅ Pre-set	`postgresdb` — connects n8n to Railway PostgreSQL
`DB_POSTGRESDB_HOST`	✅ Auto-injected	PostgreSQL private hostname via Railway reference variable
`DB_POSTGRESDB_DATABASE`	✅ Auto-injected	Database name from Railway PostgreSQL service
`DB_POSTGRESDB_USER`	✅ Auto-injected	Database user from Railway PostgreSQL service
`DB_POSTGRESDB_PASSWORD`	✅ Auto-injected	Database password via Railway secret reference
`WEBHOOK_URL`	✅ Required	Your Railway public URL — required for webhook triggers to work
`N8N_BASIC_AUTH_ACTIVE`	Recommended	Set to `true` — protects the n8n UI from public access
`N8N_BASIC_AUTH_USER`	Recommended	Username for basic auth
`N8N_BASIC_AUTH_PASSWORD`	Recommended	Password for basic auth — use a strong value
`N8N_ENCRYPTION_KEY`	Recommended	32-character random string — encrypts stored credentials
`PORT`	Pre-set	`5678` — the default n8n port

Set WEBHOOK_URL to your Railway public domain. Find it under your n8n service → Settings → Domains. Without this, webhook-triggered workflows will not receive external traffic.

Common Use Cases

Self-hosted alternative to Zapier — replace per-task billing with unlimited executions; a 10-step workflow costs 1 execution on n8n vs 10 tasks on Zapier
AI and LLM workflow orchestration — connect Claude, GPT-4o, or Gemini to APIs, databases, and business logic using n8n's native AI and LangChain nodes
Webhook-based real-time integrations — receive live events from Stripe, GitHub, Shopify, and any third-party service; apply business rules and trigger downstream actions
Business process automation — automate CRM updates, support routing, invoice processing, Slack alerts, and cross-tool data sync without execution caps
Scheduled background jobs — run cron-based workflows for reports, monitoring, data backups, and recurring operational tasks at any frequency

Frequently Asked Questions

How much does it cost to run n8n on Railway? Around $5/month on Railway's Hobby plan — with unlimited workflow executions. n8n Cloud Starter costs $20/month but caps you at 2,500 executions. Zapier Starter is $19.99/month for 750 tasks where every step in a workflow counts separately.

Do I lose my workflows if Railway redeploys? No. Everything is stored in the Railway-managed PostgreSQL database — not inside the container. Redeploys, updates, and restarts do not touch your workflows, credentials, or execution history.

Do webhooks work on Railway? Yes. Set WEBHOOK_URL to your Railway public domain and external services can trigger your workflows in real time. Railway provides automatic HTTPS — no certificate setup needed.

Can I use n8n's AI and LangChain nodes when self-hosting? Yes — all of them. Claude, GPT-4o, Gemini, Pinecone, Qdrant, and all vector store integrations are included in the free Community Edition. Bring your own API keys. No AI execution limits.

What features does self-hosted Community Edition not include vs n8n Cloud? Only enterprise-grade extras: SSO/SAML, advanced RBAC, audit log streaming, and dedicated support SLAs. All 500+ integrations, AI nodes, and core workflow features are fully available self-hosted.

How do I update n8n to a newer version? Change the Docker image tag in Railway service settings (e.g. n8nio/n8n:2.20.9) and redeploy. Your PostgreSQL data is unaffected. Pin to a specific version in production — avoid latest to prevent unexpected breaking changes.

Why Deploy n8n on Railway?

Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure so you don't have to deal with configuration, while allowing you to vertically and horizontally scale it.

By deploying n8n on Railway, you get unlimited workflow executions, a production-grade PostgreSQL backend, automatic HTTPS webhook support, and zero server administration — at ~$5/month flat, with full ownership of your data and automations.
