n8n sits alongside Zapier and Make in the workflow automation category. The characteristic that matters commercially is that it can be self-hosted.
Why self-hosting is the deciding factor
With a hosted-only tool, every record moving through a workflow passes through the vendor's infrastructure. For a business handling patient information, financial detail or anything with a residency requirement, that is a question to answer before anything is built.
Self-hosted n8n runs on infrastructure you choose, in a region you choose. The workflow definitions are files you hold. That answers both the residency question and the exit question in one decision.
What it is good at
- Connecting things that were not designed to connect. Standard integrations where they exist, HTTP requests where they do not.
- Being inspected. Each execution is visible step by step, with the data at each stage. When something breaks you can see exactly where.
- Being handed over. The workflow is a file. It can be exported, versioned and given to someone else to run.
The honest limitations
It is a workflow engine, not an application platform. Complex logic becomes awkward to express and awkward to read, and past a certain point purpose-built code is clearer and cheaper to maintain. Self-hosting also means someone owns updates, backups and uptime — real work, not zero.
Why it comes up in AI projects
Most useful AI systems are mostly not AI. They are a chain of ordinary steps with one or two model calls inside. A workflow tool gives that chain somewhere sensible to live, with the AI as a node rather than as the architecture.
Questions
- Do we own the workflows built in n8n?
- You should — that is much of the point of choosing it. Workflow definitions can be exported and handed over, so the work is portable to another team or brought in-house without a rebuild.
- Is self-hosting difficult?
- The initial setup is straightforward. The ongoing part — updates, backups, monitoring — is real but modest work, and it is the trade for keeping data and control in-house.
