n8n

An automation platform holds API keys for your CRM, your email, your payment provider and your database. n8n's answer to that is simple and unusual: run the whole thing yourself. The Community Edition is free, self-hosted, feature-complete for most purposes, and keeps every credential inside your own network.

n8n GmbH is based in Berlin. Between n8n and Czech Make, this is one of the few categories on this site where the European options are not a compromise but the leading products.

Code Where You Need It

n8n's defining feature next to Zapier is that you are never trapped by the visual builder. Any node can be a JavaScript or Python function, so awkward data transformations that would need three chained no-code steps become four lines of code. For technical teams this is the difference between a toy and a tool.

Branching, looping, error-handling workflows and sub-workflows are all first-class, so genuinely complex processes stay maintainable rather than degenerating into a chain of workarounds.

AI Agents

n8n added native AI agent nodes with LangChain integration early, and it has become one of the more common ways to build an agent that actually does something — reading from systems, calling models, writing results back. Because you can point those nodes at Mistral or a locally hosted model, the whole agent can run without leaving European infrastructure.

Licence and Cost

n8n is source-available under a Sustainable Use Licence rather than a classic open-source licence: free for internal use including commercial use, with restrictions on reselling it as a hosted service. For nearly all users that distinction has no practical effect, but it is worth knowing up front rather than discovering later.

Self-hosted, there is no per-task pricing, which is the other structural advantage over Zapier: workflows that process thousands of records cost server capacity rather than escalating fees.

Limitations to Consider

Self-hosting is real work — a server, updates, backups and a queue setup if volume grows. The interface assumes more technical fluency than Zapier's, and a non-technical colleague will not build their first automation unaided. The integration catalogue, while large, is smaller than Zapier's, so an obscure SaaS tool may need a generic HTTP node rather than a purpose-built one.

Who Should Use n8n

Technical teams that need automation touching sensitive systems, anyone whose Zapier bill has grown with task volume, and teams building AI agents that must run on European or local infrastructure.
