The short answer: self-host n8n if you care about data privacy, run high execution volumes, or want zero per-execution fees — use n8n Cloud if you want zero server maintenance and can accept usage-based pricing. For most AI agent workflows, the decision comes down to three things: cost at your execution volume, where your prompts and API keys live, and how much DevOps time you’re willing to trade.
n8n is an open-source workflow automation platform that has become a favorite for building AI agents — chaining LLM calls, tools, and memory into autonomous workflows. But before you build, you have to pick a deployment. Here’s a complete, honest comparison.
n8n Self-Hosted vs Cloud at a Glance
| Factor | n8n Self-Hosted | n8n Cloud |
|---|---|---|
| License cost | Free (open source) | Paid subscription |
| Pricing model | You pay only for infrastructure | Per-execution + subscription |
| Maintenance | You manage servers, updates, backups | Fully managed by n8n |
| Data location | Your own servers | n8n’s managed environment |
| Execution limits | Only your hardware’s limits | Capped by plan tier |
| Setup effort | High (Docker, DNS, SSL, monitoring) | Low (sign up and build) |
| Best for | Privacy, high volume, control | Speed, small teams, quick start |
The Four Factors That Actually Matter
1. Cost: Fixed Infrastructure vs Per-Execution
n8n self-hosted is free and open-source; you pay only for your own infrastructure. That’s the headline. The community edition costs nothing to license. Your real expense is a VPS or server — often $5 to $30 a month for a small instance — plus your time to run it.
n8n Cloud removes all server maintenance but applies per-execution and subscription pricing. The starter plan is modest, but costs climb as your workflows fire more often. A single AI agent that makes several LLM calls per run can burn through an execution budget quickly.
The break-even point depends on volume:
- Low volume (a few hundred executions/month): Cloud is usually cheaper and faster to start.
- High volume (thousands of executions/day): self-hosting wins because a flat infrastructure cost doesn’t scale with execution count.
2. Privacy: Where Your Prompts and Credentials Live
This is the factor that pushes most serious AI agent builders toward self-hosting.
Self-hosting keeps prompts and credentials on your own servers; Cloud stores them in n8n’s managed environment. When an AI agent processes customer data, that data flows through wherever your instance runs.
For many businesses, this is decisive:
- Handling HIPAA, GDPR, or client-confidential data
- Prompts that contain proprietary business logic
- API keys for paid models (OpenAI, Anthropic) you don’t want exposed to a third party
n8n self-hosted keeps all workflow data on your own infrastructure, while n8n Cloud processes it on n8n’s managed servers. If your compliance requirements say data must stay in your environment, self-hosting isn’t optional — it’s the only compliant choice.
3. Scaling and Execution Limits
Self-hosted n8n scales with the hardware you rent. If you hit a bottleneck, you upgrade the server. There’s no artificial ceiling on executions — only your infrastructure.
n8n Cloud caps active workflows and executions per plan. Running a large fleet of AI agents means either upgrading tiers or hitting limits. For a single agent or a small pilot, this rarely matters. For a production system, it becomes a recurring cost conversation.
4. Setup and Maintenance Effort
This is the honest trade-off. n8n Cloud is genuinely turnkey — you create an account and start building in minutes. No servers, no SSL certificates, no updates, no backups to manage.
Self-hosting means you own:
- Server provisioning (or a Docker deployment)
- Domain, DNS, and SSL setup
- n8n updates and security patches
- Backups and disaster recovery
- Monitoring and uptime
If you don’t have someone comfortable with Docker and Linux, the “free” license costs you real engineering hours. That labor is the hidden price of self-hosting.
When to Choose Each
Choose n8n Cloud when:
- You’re validating an AI agent idea and want to move fast
- Your team has no DevOps capacity
- Your execution volume is low and predictable
- You’re okay with n8n managing your environment
Choose n8n Self-Hosted when:
- You handle sensitive or regulated data
- Your workflows run at high volume
- You want flat, predictable infrastructure costs
- You need custom modules, full control, or specific infrastructure
Verdict: A Simple Decision Framework
Ask yourself three questions, in order:
- Does your data need to stay on your infrastructure? If yes → self-host. No exceptions.
- Will your execution volume be high? If yes → self-host; flat costs beat per-execution pricing.
- Do you have (or want to develop) DevOps skills? If no → start on Cloud, and migrate to self-hosted when volume or privacy demands it.
A common, sensible path: start on n8n Cloud to build and validate your agent, then migrate to self-hosted once you have real volume or stricter privacy needs. n8n makes migration straightforward since workflows export and import cleanly between environments.

FAQ
Is n8n self-hosted free?
Yes. The community edition is free and open-source — you pay only for the infrastructure you run it on. Paid self-hosted tiers add features like SSO and external secrets, but the core platform is free.
Does self-hosting n8n keep my AI workflow data private?
Yes. Self-hosting keeps prompts, credentials, and workflow data on your own servers, while n8n Cloud processes them in n8n’s managed environment. If privacy or compliance is a requirement, self-hosting is the way to go.
How much does n8n Cloud cost for AI agents?
n8n Cloud uses subscription plus per-execution pricing. Costs depend on how many times your agent workflows run. High-volume AI agents that make multiple LLM calls per run can push you into higher tiers quickly, which is why high-volume builders often self-host.
Should I self-host n8n or use n8n Cloud?
Self-host if you need data privacy, run high volumes, or want flat infrastructure costs. Use Cloud if you want zero maintenance and can accept usage-based pricing. Many builders start on Cloud and migrate to self-hosted as they scale.
