Self-hosted n8n: the complete guide.

The three reasons that tip the scale.

n8n comes in two versions: the official cloud (n8n.cloud, run by the publisher) and self-hosting on your own server. Same product, same workflow editor, same integrations. Three differences tip the balance.

The cost model. Cloud bills by execution tiers: €20/month for 2,500 executions at the first tier, rising with volume from there. Self-hosted costs the price of your server, full stop. A workflow running every 15 minutes already generates 2,900 executions a month on its own: as soon as you're automating seriously, the cloud meter becomes the topic, while the VPS doesn't move.

Data location. Your workflows handle leads, invoices, customer data. Self-hosted, everything flows through your server, at the European host you chose. Your data-processing register gets simpler, and so do your enterprise clients' vendor security questionnaires.

No cap. No execution limit, no limit on active workflows, full access to technical features (code, HTTP requests, queues). Your instance grows with your needs, not with a pricing grid.

License, limits, prerequisites: the honest picture.

The fair-code license

n8n isn't open source in the strict sense: it's fair-code (Sustainable Use License). In practice: internal use at your company is free, including commercial use. The restriction: you can't resell n8n itself as a service. For an SMB automating its own operations, the license costs nothing and constrains nothing.

What stays reserved for paid tiers

The free self-hosted version covers the essentials: every integration node, unlimited workflows, custom code, webhooks. Some team features stay reserved for the publisher's paid tiers: SSO, advanced per-project permissions, log streaming, externalized secrets management. For most SMBs, nothing blocking; at the scale of a mid-market company with several teams, it becomes a real question worth costing out.

The technical prerequisites

• A VPS from a European host: Hetzner, OVHcloud, Scaleway. 1 vCPU and 2GB of RAM to start, 2 vCPU and 4GB for comfort.
• A dedicated subdomain (for example n8n.yourdomain.com) pointing to the server.
• A standard Docker install, the method recommended by the publisher: clean, isolated, easy to update.
• One person comfortable with a terminal, in-house or at your partner. Nothing more is needed.

n8n in production in 5 steps.

The sequence below is what we deploy for our clients, described deliberately without diving into the technical weeds: what matters for deciding is the real effort of each step. The guiding principle never changes: secure access and backups from day one.

Total time for a clean install: half a day, security and backups included. For the step-by-step technical detail, n8n's official documentation (docs.n8n.io) covers every variant, command by command.

Under €30/month, maintenance included.

The three-year comparison makes the point: a self-hosted instance costs around €900 over 3 years (VPS + monitoring), while the same workload on per-operation billed platforms runs into the thousands of euros. As your automations multiply, the gap widens: every new workflow is free on self-hosted, billed by usage elsewhere.

This microscopic infrastructure cost is also what makes more ambitious systems viable: a 24/7 AI agent orchestrated by n8n runs on the same machine, and the full budget breakdown for an agent is in How Much Does an AI Agent Cost.

Your data stays with you.

This is the deciding argument for many of our clients, and it's simple to understand: an automation workflow sees everything it processes pass through it. Incoming leads, supplier invoices, HR data, customer exchanges. The question "where does this data actually go" deserves a precise answer.

Self-hosted, the answer fits in one line: on your server, at the European host you chose, under contract with you. You choose the location, you keep the list of subprocessors, you control the logs and retention periods. When an enterprise client sends you their security questionnaire, every answer is in your hands.

Three practices round out the setup, and we apply them systematically:

• Encrypted credentials, a key kept safe. n8n encrypts the login credentials to your tools; the encryption key is kept off the server.
• Named accounts and a secure connection. One account per person, never shared, and the interface accessible only over HTTPS.
• Controlled execution retention. Execution logs contain the data that was processed: we configure automatic purging to keep only what's necessary.

For balance: n8n Cloud is a serious offering from a European publisher (German), with its own commitments. Self-hosting doesn't win by default against the other option; it wins through the level of control it gives you.

When n8n Cloud is still the right choice.

Honesty first: self-hosting isn't the right answer for everyone. Three situations where we recommend the cloud without hesitation.

• No one to run the server. No terminal skills in-house, no partner: the cloud removes the question entirely. A poorly maintained instance is worse than a subscription.
• Small volume, fast start. A handful of workflows, under 2,500 executions a month: €20/month with zero management is a good deal for validating use cases before industrializing.
• Need for managed team features. SSO, separate environments, vendor support under SLA: if these requirements arrive before the infrastructure skills do, the managed paid tier answers directly.

The typical trajectory we see: start on cloud to validate, switch to self-hosted once volume and data stakes rise. The migration is simple (workflows transfer as-is, credentials get recreated) and takes half a day to a full day.

What AUTOMATE ALL runs in production.

n8n is one of the pillars of our orchestration stack, alongside custom Python and PostgreSQL. Across 25+ systems in production, our deployment standard has settled into:

• Hardened instance: access only over an encrypted connection, nothing exposed unnecessarily, named accounts, minimal firewall.
• Tested daily backups: volume + database, externalized, restore verified.
• Active monitoring: alerts on workflow failures, disk space, certificates. Grafana dashboards when volume justifies it.
• Separated environments: a staging space, a production one. A workflow never ships to production without a dry run.
• 100% client ownership: server, workflows, credentials, documentation. You keep everything if our paths ever separate.

The method for deciding what to automate first is detailed in How to Automate a Business Process in 2026, and the full set of our disciplines is on the Services page.
