1 / 2The Story
n8n is a workflow automation tool that connects services through a visual node editor. A workflow is a graph: a trigger node starts it, and subsequent nodes call APIs, transform data, or branch on conditions.
The product sits between two categories. It is more visual than writing an integration script, and more code-friendly than a consumer automation tool: nodes can include JavaScript expressions, and a code node can run arbitrary logic inside the workflow. That combination is what lets it handle a transformation that a purely visual builder cannot express.
n8n is published as source and can be self-hosted, which matters for teams that need automation to run inside their own network. The hosted cloud is the commercial layer. The self-hosted deployment is the same core, so a workflow can move between them.
Overview
n8n's position is that a visual builder should not forbid code when a transformation needs it.
A workflow is a directed graph of nodes. A trigger node starts the run - a schedule, a webhook, or an application event - and each subsequent node receives the previous node's output.
Nodes cover common services directly, and a code node runs JavaScript when the built-in operations are not enough. Expressions can reference earlier node data, so a value computed in one node is available downstream without a separate mapping step.
The core is published and self-hosting is supported. A team that must keep automation inside its own network can run n8n itself, and the same workflows run on the hosted cloud.
Key Features
- Visual node editor
A workflow is a graph a reader can follow, rather than a script whose control flow is implicit.
- Inline JavaScript
A code node runs arbitrary logic, so a transformation the built-in nodes cannot express is still possible.
- Self-hostable
The core runs on your own infrastructure from the published source.
- Trigger variety
Schedules, webhooks, and application events can all start a workflow.
Where n8n is a strong choice, and where it is not
Choose n8n if you want automation a non-developer can read, but you still need the option to drop into code for the steps that a visual builder cannot express.
Look elsewhere if you need a fully managed service with no operational surface, or if your workflows are simple enough that a script in your own application is clearer.
Getting started
A first workflow can run in minutes; the value compounds once you connect real credentials.
- ~10 minTime to first workflow
Add a trigger, add an action, and execute. The editor runs workflows without a deploy step.
- FreeCost to start
Self-hosted and free. The cloud plan is priced by executions.
- Node or DockerPrerequisites
Node.js or Docker for self-hosting. Credentials for whichever services you connect.
Known limitations
Constraints confirmed from the project's documentation.
- Self-hosting means you own the reliability. A workflow that matters needs the instance monitored, backed up, and upgraded.
- Execution-based pricing on cloud. Cost scales with workflow runs, which is unpredictable for a chatty automation.
- Complex logic gets awkward visually. A large workflow with many branches is harder to review than the equivalent code.
- Credentials live in the instance. A self-hosted deployment concentrates access to every connected service, so its security is load-bearing.
Pick n8n if you want automation you can host and extend with code
It combines a visual editor with the ability to drop into JavaScript, which covers the cases a purely visual tool cannot express.
The differentiator is the escape hatch: a node can run custom code, so a workflow is not limited to what the built-in nodes support. Combined with self-hosting, that makes it viable for automations touching sensitive systems.
If you want zero operational work and your workflows are simple, a fully hosted automation service is less to maintain.
FAQ
What is n8n?
n8n is a workflow automation tool that connects services through a visual node editor, with the option to run JavaScript inside a workflow.
Is n8n open source?
Yes. The core is published in a public repository with a license file. Check the repository for current license terms, which are not a standard permissive license.
Can I self-host n8n?
Yes. Self-hosting is supported, and the operator becomes responsible for upgrades, backups, and security.
Is n8n free?
n8n lists a free self-hosted tier alongside paid cloud and enterprise plans. Check the pricing page for current terms.
What stack is n8n built with?
CompassPad records n8n as a TypeScript and Node.js server with a Vue front end and SQLite or PostgreSQL storage, based on the public repository.
