n8n Automation
10 articles · written by Niraj Kumar
n8n is the automation tool worth self-hosting: the workflows are inspectable, the data stays on your infrastructure, and it will happily call your own APIs and local models. These articles cover running it seriously rather than as a hobby instance.
Coverage includes hosting n8n on AWS EC2 behind Nginx with TLS and backups, webhook-driven workflows that back internal tools, wiring n8n to AI APIs for intelligent pipelines, a privacy-first self-hosted stack pairing n8n with Ollama in Docker, and an honest comparison against Make and Zapier including where the hosted tools win.
