Deploy and Host n8n on Railway

n8n is an open-source workflow automation tool that lets you connect apps, APIs, and databases to automate anything from moving data between Google Sheets and Slack to building complex backend integrations.

With this one-click Railway deployment, you get a fully configured, production-ready n8n setup complete with PostgreSQL for data storage.

It’s ideal for developers, teams, and creators who want to build scalable automation systems without managing servers or infrastructure.

About Hosting n8n Production

Deploying n8n on Railway is as simple as it gets, just click the Deploy Now button on the template page, and within a minute, your complete automation stack will be live. No setup, no terminal commands, no configuration headaches. Everything comes prewired and ready to go.

Behind that one-click setup, this template automatically provisions and connects two core services:

• n8n: the workflow automation engine and user interface
• PostgreSQL: database that can be used in the n8n workflows (to store chat history of an AI agent, for example)

These components are already linked using Railway’s built-in environment variables, so you don’t have to worry about managing credentials or connection strings. It’s all handled securely under the hood.

For most users, the default configuration works perfectly out of the box. But if you like to fine-tune things, we’ve left a few knobs for you to tweak, all exposed as environment variables in your Railway dashboard:

• Execution Pruning (EXECUTIONS_DATA_PRUNE, EXECUTIONS_DATA_PRUNE_MAX_COUNT) — decide how long to keep historical workflow runs

Every parameter is well-documented in the official n8n environment variable reference, so you can safely explore and tune them to fit your use case. See the full reference here.

Common Use Cases

Whether you’re automating simple daily tasks or building complex AI-powered workflows, n8n on Railway can handle it all. Here are some of the most popular ways developers, teams, and creators use n8n in real-world scenarios:

Great for creators searching “how to automate TikTok or YouTube uploads with n8n.”
Example: AI video creation and TikTok auto-upload workflow.

4. Finance & Stock Market Workflows Using n8n

Automate real-time stock or crypto analysis using APIs like Polygon or Binance, process the data with Claude or GPT-4o, and get insights via Telegram.
Targeted searches: “AI stock analysis bot with n8n.”
Example: AI Stock Analysis Assistant

5. LinkedIn job automation using n8n

Combine LinkedIn Jobs API, Bright Data, and Google Sheets to find matching job listings, apply automatically, or send personalized messages.

Comparison with Other Tools

If you’ve ever searched for automation platforms like Zapier, Make (Integromat), or Pipedream, you know there are plenty of options. Here’s how n8n compares to some of the most popular tools, especially when deployed on Railway, where you get complete control, scalability, and cost predictability.

1. n8n vs Zapier

• What it is: A popular no‑code automation platform with thousands of pre-built app integrations.
• Focus area: Non-technical users wanting quick, plug-and-play workflows.
• Why n8n is better: Offers self-hosting, full control over your data, and a cost-effective model for multi-step workflows. Ideal for teams who need production-ready, scalable automations.
• Cost: Free tier (~100 tasks/month), paid plans start at ~$20/month (task-based).

2. n8n vs Make (formerly Integromat)

• What it is: Visual automation builder with conditional logic and multi-step workflow support.
• Focus area: Marketers and ops teams needing complex visual flows.
• Why n8n is better: Supports queue mode with Redis + Postgres, self-hosting, and per-execution pricing, making it cheaper and more flexible for heavy workflows.
• Cost: Free tier available; paid plans from ~$9/month (operation-based).

How to Use n8n

n8n lets you automate tasks by building workflows visually. You connect nodes on a canvas, allowing data to flow from one step to the next. Each workflow starts with a trigger node and can include multiple action nodes, conditional logic, or even custom code all without writing a full application from scratch.

Core Concepts

• Nodes: The building blocks of n8n. Each node performs a specific task, such as connecting to an app (Google Calendar, Slack), executing a logic operation (If/Else), or running custom code.
• Trigger: The starting point of a workflow. Triggers listen for events like a new email, a scheduled time, or a manual execution to start the workflow.
• Execution: A single run of a workflow. Every time a trigger fires, it generates a workflow execution.
• Expressions: Dynamically manipulate and reference data from previous nodes. For example, use an expression to insert a form submission’s name into an email.

Implementation Details

PostgreSQL acts as a persistent store for workflow execution data, agent memory, logs, and other details, offloading memory from the UI and keeping the workflows safe across restarts.

Key PostgreSQL Environment Variables

The template preconfigures the following variables:

• DB_TYPE
• DB_POSTGRESDB
• DB_POSTGRES_USER
• DB_POSTGRES_PASSWORD
• DB_POSTGRES_HOST
• DB_POSTGRES_PORT

Note: In complex workflows, long-running tasks can slow down the UI if everything runs on a single node. If you face such issue, you can go for following template which separates the worker and primary n8n nodes:

FAQ

1. What is n8n?
   n8n is an open-source workflow automation tool that lets you connect apps and services visually, build automated workflows, and integrate data without writing full applications.

2. Is n8n free to use?
   Yes, n8n offers a free Community Edition for self-hosting with unlimited workflow executions, while n8n Cloud has paid plans for managed hosting.
