The Solo Developer’s Secret Weapon: Self-Hosted Automation with n8n

A solo developer explains why they replaced custom Ruby/Rails integration scripts with self-hosted n8n workflows. Two concrete use cases are shown: a new-user onboarding flow that triggers a webhook from Rails and fans out to Beehiiv, Discord, and Google Sheets; and a nightly database report that queries Postgres, summarizes metrics via OpenAI, and sends results to Telegram. The post argues that 'glue code' (integrations, alerts, data syncing) should be offloaded to visual automation tools rather than maintained as custom code, keeping the core Rails app lean. n8n is positioned as a developer-friendly, self-hostable alternative to Zapier, deployable on a $5 VPS with Docker.
