Self-hosted n8n

A PostAI node for n8n you actually load yourself.

Not on npm. Not in the n8n.io community registry. Clone this repo, build the package, point self-hosted n8n at it. Needs a Pro ($49/mo) API key from Dashboard → API Keys.

pnpm --filter n8n-nodes-postai build
export N8N_CUSTOM_EXTENSIONS=/absolute/path/to/packages/n8n-nodes-postai
n8n start
