n8n Self-Hosted Setup
& AI Workflow Automation

n8n (pronounced 'n-eight-n', short for 'nodemation') is an open-source workflow automation platform that gives you complete control over your data and infrastructure. Unlike cloud-only tools like Zapier or Make.com, n8n can be self-hosted on your own server, meaning your workflow data, credentials, and execution history never leave your environment. It provides a visual editor where you connect nodes to build automations, supports 800+ integrations, custom JavaScript and Python code nodes, webhooks, cron scheduling, and built-in AI/LLM nodes for connecting Claude, GPT, and Gemini directly into your workflows. For teams that value data ownership and cost efficiency, n8n is the clear choice — especially when paired with a professional setup that handles Docker, SSL, PostgreSQL, and security hardening from day one.

The biggest difference is pricing and control. Zapier charges per task (starting at $29.99/month for 750 tasks), Make charges per operation ($10.59/month for 10,000 ops), while self-hosted n8n is completely free with unlimited executions. n8n also gives you full control over your data (it runs on your server), supports custom JavaScript and Python code nodes, has built-in AI/LLM integration nodes, and offers advanced branching logic. Zapier wins on number of integrations (7,000+ vs 800+), but n8n covers all major tools and lets you build custom API connections.

Yes. Self-hosted n8n is free under a 'Fair Code' license (Sustainable Use License). You can run it on your own server with unlimited workflows, unlimited executions, and no per-task fees. n8n also offers a paid cloud version starting at approximately $24/month if you prefer not to self-host. Our setup service covers the one-time professional installation — you pay only for your VPS hosting ($4-30/month) after that.

Self-hosting n8n provides several critical advantages over the cloud version that go beyond simple cost savings. First, you get unlimited executions regardless of plan — n8n Cloud imposes execution limits that can become expensive at scale. Second, your data stays entirely on your server, which matters for GDPR compliance, healthcare workflows, and financial data processing. Third, hosting costs are dramatically lower: a Hetzner VPS at $4/month versus $24+/month for cloud, saving over $240 annually. Fourth, you can install community nodes and run AI models with your own API keys at zero markup, unlocking capabilities that cloud plans restrict. Finally, self-hosting eliminates vendor lock-in — your workflows, credentials, and execution history are fully portable. We handle the Docker Compose deployment, PostgreSQL setup, SSL certificates, and security hardening so you get production reliability without the DevOps overhead. If data privacy is your top concern, explore our self-hosted AI deployment options.

A Linux VPS with at least 1 vCPU, 2GB RAM, and 20GB storage. We recommend 2 vCPU and 4GB RAM for production workloads with many concurrent workflows. Docker and Docker Compose are required (we install them). A domain name is needed for SSL/HTTPS. Popular choices: Hetzner ($4/month), DigitalOcean ($6/month), or Oracle Cloud (free tier with 4 ARM CPUs and 24GB RAM). Check our self-hosted AI page for hardware recommendations if you plan to add local AI models.

We deploy n8n using Docker Compose with a multi-container setup: the n8n application container, a PostgreSQL database container for reliable data storage, and an Nginx reverse proxy container for SSL termination and custom domain routing. Docker Compose handles container orchestration, automatic restarts on failure, volume mounts for persistent data, and environment variable management. This is the recommended production deployment method by the n8n team.

PostgreSQL, always. SQLite is the default for quick local testing, but it does not handle concurrent workflow executions well and can corrupt data under load. PostgreSQL provides proper transaction handling, concurrent access, reliable credential encryption, and much better performance for execution history queries. Every production n8n deployment we build uses PostgreSQL.

n8n encrypts all credentials at rest using AES-256 encryption with a unique encryption key you control. Credentials are stored in the PostgreSQL database and are never exposed in workflow exports or logs. When you share or export a workflow, credentials are automatically stripped. We configure the encryption key during setup and include it in your backup documentation. For organizations with stricter requirements, see our self-hosted AI deployment options with full-disk encryption and air-gapped configurations.

Yes — and this is one of n8n's most powerful differentiators. n8n has built-in AI nodes for OpenAI (GPT-4o, GPT-4), Anthropic (Claude 4 Opus, Claude 4 Sonnet), Google (Gemini 2.5 Pro, Gemini 2.5 Flash), Mistral, Ollama (local models), and more. Beyond simple prompt-response interactions, n8n includes LangChain integration nodes for building multi-step AI agent chains with tools, memory, and RAG (Retrieval-Augmented Generation) pipelines. This means you can build workflows where an AI agent receives a customer email, searches your knowledge base, drafts a context-aware response, checks if escalation is needed, and either sends the reply or creates a support ticket — all within a single visual workflow. This is significantly ahead of what Zapier and Make offer in terms of AI capability, and it is the core reason our AI automation clients choose n8n as their workflow backbone.

AI agent workflows in n8n go beyond simple 'send prompt, get response' automations. They use LangChain-based agent nodes that can reason about tasks, use tools (web search, database queries, API calls), maintain conversation memory, and make decisions across multiple steps. For example: an AI agent that receives a customer email, searches your knowledge base, drafts a response, checks if escalation is needed, and either sends the reply or creates a support ticket — all in one workflow.

Self-hosted n8n is free with unlimited executions. Your only cost is VPS hosting ($4-30/month). Zapier starts at $29.99/month for 750 tasks and goes to $149.99/month for 2,000 tasks on their Professional plan. If you run 10,000+ automations per month, Zapier can cost $400-800+/month while n8n remains at your fixed VPS cost. n8n Cloud (if you prefer not to self-host) starts at approximately $24/month.

Yes. n8n supports queue mode with Redis and multiple worker processes for horizontal scaling. This allows you to distribute workflow executions across multiple worker containers, handle thousands of concurrent webhook triggers, and process large data volumes without bottlenecks. We configure queue mode for enterprise clients who need high throughput and reliability.

With our Docker Compose setup, updating is a single command: pull the new image and restart the container. We configure your setup with pinned major versions and provide update instructions. For clients on our support plan, we handle updates for you — including testing workflows after the upgrade to ensure nothing breaks.

Our Docker Compose setup includes automatic restart policies — if n8n crashes, Docker restarts it within seconds. We also configure automated PostgreSQL backups (daily by default) so your workflows, credentials, and execution history are recoverable. For enterprise clients, we set up monitoring alerts (UptimeRobot or similar) that notify you immediately if the instance becomes unreachable.

Yes. While there is no one-click migration tool, most Zapier Zaps and Make scenarios can be recreated in n8n — often with more capability since n8n supports code nodes and advanced branching. We help clients migrate their most important automations as part of the setup service, and we build them better with n8n's more flexible architecture.

Standard n8n setup (Docker, PostgreSQL, SSL, security hardening) takes under 2 hours. If you add AI workflow building, it takes 3-5 hours depending on the number and complexity of workflows. Everything is tested and verified before handoff — no half-configured deployments.

You can install n8n yourself with 'docker run' in 5 minutes. But getting it production-ready — PostgreSQL instead of SQLite, Nginx with SSL auto-renewal, proper Docker Compose orchestration, security hardening, backup strategy, custom domain, SMTP configuration, AI node setup, and actually building useful workflows — takes days of debugging and documentation reading. We have deployed n8n for over 10 clients across industries from SaaS to e-commerce, and know every pitfall: from Nginx proxy buffering issues to PostgreSQL connection pool tuning to n8n's encryption key management. You skip the learning curve and get a battle-tested production setup from day one. Check our case studies to see how our automation setups perform in production.
