The honest brief
n8n
The self-hostable Zapier alternative with first-class AI/LangChain nodes and per-execution (not per-task) pricing.
- Free Community Edition
- 500+ integrations
- Visual builder bridging APIs and databases
- Per-execution pricing, not per-task
- Code nodes for full control
- Fair-code license, not OSI open-source
- Self-host carries ops overhead
- Steeper than Zapier for non-technical users
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
