n8n Tutorial #6: How to Connect n8n to Supabase (Free Database Setup for Automations)

This is Part 6 of my n8n beginner-to-pro playlist. In this lesson, we’re taking a big step forward: connecting n8n to a real database.

Google Sheets was fine for early demos, but if you want scalable automations, AI agents, or serious workflows, you need a proper database. That’s where Supabase comes in — free Postgres in the cloud with a simple API.

In this video you’ll learn:

✅ How to create a free Supabase project

✅ How to grab your Host + Service Role Key

✅ How to add Supabase credentials in n8n

✅ How to build a Weather API → Supabase workflow

✅ How to fix row-level security errors

👉 Keep watching this playlist to follow along step by step — by the end, you’ll be building full AI-powered automations with n8n.
