n8n.
On your own server.

Connect services and build repeatable workflows with a self-hosted automation platform.

What it is for.

Common uses of n8n.

Common uses

  • Service integrations
  • Scheduled workflows
  • Webhook-driven tasks

Keep in mind

Secure webhook endpoints and the administration interface. Back up workflow data and the encryption configuration together.

Sizing and setup.

Planning examples, not official minimum requirements.

Installed for you?
No. Your preference is saved with your configuration

Before you install

Check the current supported operating systems, deployment methods, dependencies and licence terms. What you need depends on your workload, not just the application's name.

Large datasets and busy workloads can need far more memory, storage or different hardware. Any external API or service subscriptions are separate.

Things to decide before you install n8n.

Advice specific to this application.

Size around concurrent workflows

A quiet automation instance and one processing several active workflows have different demands. Review execution frequency, payload size and how much data a workflow keeps in memory. Distinguish scheduled polling from externally triggered webhooks when planning activity and access.

Preserve the data needed for restoration

Workflow definitions are only part of the recovery material. Keep the database and encryption configuration needed to use stored credentials together, protect the backup and test restoration separately. Restrict the editor interface and decide which webhook endpoints need public access.

Get the server ready.

Linux guides that help with this setup.

A repeatable deployment.

Four steps that make the environment easier to maintain.

  1. 01

    Check requirements

    Read the publisher's instructions and choose a supported installation method.

  2. 02

    Limit access

    Protect the dashboard, credentials and network endpoints before you expose any service.

  3. 03

    Persist your data

    Work out where the application keeps its state and store it separately from replaceable runtime files.

  4. 04

    Test recovery

    Back up the data and configuration, then check that you can restore them.

A checklist to keep.

Run through it before and after you install.

n8n questions.

Quick answers before you choose resources.

Does choosing this application install it?

No. The configurator only saves your application preference. It does not connect to any infrastructure or run an installer.

How much memory will I need?

Use the planning example as a starting point only. Check the publisher's requirements and measure the whole stack under a realistic workload.

Who maintains the application?

You do. Self-hosted applications need updates, configuration and recovery planning from the operator. The publisher's documentation describes supported maintenance.

Where can I learn the server basics?

The knowledge base covers Linux access, packages, services, firewalls and backups.
