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
