n8n

n8n is an open-source workflow automation platform. It provides a visual interface for connecting apps and services, with built-in AI nodes for LLM operations. Respan gives you full observability over every workflow execution and AI node call through a community node.

Create an account at platform.respan.ai and grab an API key.

Run npx @respan/cli setup to set up with your coding agent.
