Custom Code Node Execution With Node Js Runtime

via “custom code execution with sandboxed function nodes”

Build AI Agents, Visually

Unique: Implements custom function execution via a sandboxed Node.js VM (Custom Function Execution section in DeepWiki) that validates function signatures and restricts access to dangerous APIs; the system provides a limited set of safe utilities (HTTP client, JSON parsing) and logs execution errors for debugging

vs others: More accessible than writing custom LangChain tools because users can write code directly in the UI without creating separate Python/JS modules or managing dependencies
