What self-host actually costs
n8n self-hosted is zero licensing fees. But production-grade self-host requires: a server (or Kubernetes), PostgreSQL, a reverse proxy, HTTPS certificates, monitoring, backups, and someone on call when a workflow errors at 2am. At typical DevOps rates ($100/hr loaded), even a modest production deployment absorbs 4–8 engineering hours per week. n8n Cloud ($20+/month) removes the hosting work, but building and maintaining workflows still lands on your team.
