n8n (pronounced "n-eight-n", short for "nodemation") is a fair-code workflow automation platform. It lets you connect APIs, databases, and AI models into automated pipelines using a visual node-based editor — without writing code for the plumbing.
It is the open-source answer to Zapier and Make. Self-hostable, extensible, and powerful enough to run production-grade automations that actually scale.
Why teams pick n8n in 2026
Three things tipped n8n from "hobbyist tool" into "the default automation layer for serious teams":
- Self-hostable — your data stays on your infrastructure. Critical for healthcare, finance, and any team handling customer PII.
- Native AI nodes — first-class integration with OpenAI, Anthropic, and local LLMs. You can chain a Claude call into a database write into a Slack message in under 10 minutes.
- Predictable cost — fair-code license, no per-execution pricing. Run 10 workflows or 10 million; the bill does not change.
When n8n beats writing code
Plumbing work — moving data between systems, scheduling jobs, handling webhooks, retrying failures — is where n8n earns its keep. A workflow that would take 200 lines of glue code becomes 6 nodes you can audit visually.
It is not the right tool for everything. Custom UIs, complex business logic, and high-throughput APIs still belong in code. But for the 70% of internal automation that exists in every company, n8n closes the gap between idea and shipped pipeline.
