The honest brief

Flowise

Drag-and-drop counterpart to code-first frameworks — builds on LangChain/LlamaIndex nodes, self-hosts via npm/Docker.

  • Visual, low-code agent builder
  • Apache-2.0 core, self-hostable
  • Provider-agnostic node ecosystem
  • Multi-agent flows on a canvas
  • Complex logic outgrows the canvas
  • Less control than writing code
  • Cloud tier is a separate paid product

Sim

Figma-like canvas plus natural-language Copilot flow generation on a modern TS stack — ships a flow as API, cron, webhook, or chat.

  • Clean visual canvas, cleaner than Flowise/Langflow
  • Copilot generates flows from natural language
  • Deploys as API, schedule, webhook, or chat app
  • Open-source (Apache-2.0), self-host via npm/Docker
  • Tiny team vs n8n/Dify/LangChain ecosystem
  • Self-host still needs a Copilot API key from sim.ai
  • Younger, smaller integration library than n8n
  • Less mature knowledge-base tooling than Dify
