Deep-dives into n8n, Zapier, Make.com, OpenAI integrations, Django/FastAPI, and real-world automation patterns — from someone who ships these daily.
After building 30+ automation workflows across all three platforms for clients in USA, UK, Germany, and Australia — here's my honest take on when to use each one, total cost of ownership, and which wins for CRM automation, AI integration, and complex multi-branch logic.
