OpenClaw vs n8n: when to use an AI agent, a workflow tool, or both

By the serverserv team · 6 min read · Updated 15 October 2026

OpenClaw is an AI agent: you ask it for something in a chat app and it decides the steps itself. n8n is workflow automation: you design the steps once and it runs them the same way every time. Use OpenClaw for open-ended requests and n8n for repeatable processes. This OpenClaw vs n8n guide compares the two side by side, shows when to combine them and what each costs to run.

What is the difference between OpenClaw and n8n?

The difference is who decides the steps. In OpenClaw, an AI model decides what to do for each request. In n8n, you decide the steps in advance and the workflow follows them exactly.

OpenClaw is a free, open-source personal AI agent. It runs on your own server, connects to a model provider such as Anthropic, OpenAI or Google, and takes requests through chat apps like Telegram, WhatsApp, Slack and Discord. Its tagline is "The AI that really does things": it can browse, use tools and act for you.

n8n is a visual workflow automation tool. You connect apps with drag-and-drop nodes, and each workflow starts from a trigger such as a schedule, a webhook or a new form entry. It has AI nodes, so a workflow can call a model as one of its steps, but the overall path is fixed by you.

A simple test: if you can draw the process as a flowchart before it runs, it is an n8n job. If the right steps depend on what the request says, it is an agent job.

OpenClaw vs n8n side by side

Both are self-hosted tools that run well on a small server, but they differ in licence, cost model and how you work with them.

	OpenClaw	n8n
Type	Autonomous AI agent	Workflow automation
How you use it	Chat with it in messaging apps	Build workflows in a web editor
Who decides the steps	The AI model, per request	You, in advance
Same input, same result?	Not always	Yes
Licence	MIT (open source)	Sustainable Use License (fair-code)
Paid editions	None; no official hosted tier	n8n Cloud, Business and Enterprise
AI model needed?	Yes, always	Only for AI steps
Typical minimum server	1 GB RAM (2 GB+ recommended)	1 vCPU, 2 GB RAM
Best for	Varied requests, research, personal assistant tasks	Repeatable business processes

When should you use OpenClaw?

Use OpenClaw when the requests vary and you want an assistant that works out how to handle each one. It suits personal and small-team work where flexibility matters more than identical results.

A personal assistant in your chat app. Ask it on Telegram or WhatsApp to summarise a long thread, find a document or draft a reply.
Research. Give it a question and let it browse, read and report back.
Tasks that change each time. "Compare these three suppliers" or "check what changed on this page since last week".
One assistant across many channels. OpenClaw supports 29 channels, so the same agent can answer in Slack at work and Signal at home.

The trade-off is control. An agent with broad permissions can make mistakes, and it can be misled by prompt injection hidden in a web page or message. Give it only the access each task needs, install skills from sources you trust, and run openclaw security audit after setup.

When should you use n8n?

Use n8n when you know the exact steps and want them to run reliably, every time, with a record of each run. It suits business processes that must not improvise.

Lead handling. A new form entry goes to your CRM, your email list and a chat alert.
Scheduled reports. Pull figures from several apps every Monday and send one summary.
Webhooks. Receive an order or payment event and update other systems.
Document flows with AI steps. Extract fields from an invoice with a model, then file the result in a fixed place.

n8n keeps an execution history, so you can see what ran, when and with what data. On your own server, n8n Community Edition has no execution or workflow caps, while n8n Cloud Starter includes 2,500 executions a month at the time of writing. For setup details, see self-hosting n8n.

Can you use OpenClaw and n8n together?

Yes, and many setups benefit from both: n8n runs the fixed, high-volume processes, and OpenClaw handles the open-ended requests that come in through chat.

A common pattern is to let each tool do what it is good at:

Build the reliable parts as n8n workflows that start from a webhook, such as "create an invoice" or "add a contact to the CRM".
Let the agent call those webhooks when a chat request needs one, instead of giving the agent direct access to your business systems.
Have n8n send results or alerts back to the chat channel where the agent lives.

This keeps sensitive steps in a workflow you designed and can audit, while the agent handles the conversation. It also limits what a confused or misled agent can do, because it can only trigger the workflows you exposed.

Running both on separate servers is the cleaner option. OpenClaw's security model is "one trust boundary per gateway", and n8n stores credentials for your business apps. Keeping them apart means a problem in one does not expose the other.

How do the costs of OpenClaw and n8n compare?

Both tools are free to run on your own server, so your main costs are the server and, for OpenClaw, the AI model. The licences differ in what you may do commercially.

OpenClaw is MIT-licensed with no paid edition. You pay for a server and for model usage, either by API key or by signing in with a ChatGPT or Codex subscription.
n8n Community Edition is free to self-host under the Sustainable Use License, for your own internal business or personal use. It does not let you host n8n as a service for clients to build workflows. Features such as SSO, projects and Git need a paid n8n licence. Model costs apply only to AI steps.
n8n Cloud costs $24 a month for Starter or $60 for Pro on monthly billing at the time of writing, with execution limits.

Which serverserv plan fits OpenClaw, n8n or both?

For one person, start with the Starter plan of the tool you need. Both come pre-installed and set up, at the same prices.

Plan	Specs	Monthly	3-year term
OpenClaw Starter	2 vCPU, 4 GB, 50 GB NVMe, OpenClaw pre-installed	$14.99	$10.99/mo
n8n Starter	2 vCPU, 4 GB, 50 GB NVMe, n8n pre-installed, unlimited workflows and executions	$14.99	$10.99/mo
KVM 2 (install both yourself)	2 vCPU, 8 GB, 100 GB NVMe, full root access	$23.99	$16.49/mo

For both tools, two Starter plans keep them on separate servers. If you are comfortable with Linux, a single KVM VPS can run both. Every plan renews at the price you paid. See the OpenClaw hosting and n8n hosting pages, or open a ticket if a plan is not in the order form yet.

Questions

Is n8n an AI agent?

Not by itself. n8n is workflow automation with AI nodes, so you can build agent-like steps inside a workflow, but you design the overall path. OpenClaw is an agent that decides its own steps.

Can I switch between OpenClaw and n8n?

Your workflows and agent settings do not convert from one tool to the other, because they work differently. If you want to change the app on a serverserv plan, open a ticket and we will confirm the options for your plan.

Is OpenClaw free like n8n?

OpenClaw is free under the MIT licence with no paid edition. n8n Community Edition is free to self-host under the Sustainable Use License, which limits some commercial uses.

Which is safer, OpenClaw or n8n?

n8n is more predictable because it only does the steps you built. OpenClaw needs more care: limit its permissions, vet skills and keep its Gateway off the public internet, as its security docs advise.

Do I need both OpenClaw and n8n?

Only if you have both kinds of work. Many people start with one: n8n for fixed business processes, OpenClaw for a personal assistant, and add the other later.
