How do I replace ManyChat with Claude + n8n?
Three steps. About two hours including Meta app review.
Step 1: Self-host n8n
bash
# Local dev
npx n8n
# Production via Docker
docker run -it --rm --name n8n -p 5678:5678 \
-v n8n_data:/home/node/.n8n \
docker.n8n.io/n8nio/n8n
The official repo is github.com/n8n-io/n8n — 187k stars.
Step 2: Get an Instagram / Messenger webhook
Create a Meta app at developers.facebook.com, add the Instagram Messaging product, point the webhook at https://your-n8n.com/webhook/ig-dm. The Meta side is free.
Step 3: Add a Claude credential in n8n
In n8n: Credentials → New → Anthropic. Paste your Claude API key.
