What Is n8n? n8n 是什么？
n8n is an open-source project with 193k+ GitHub stars. Licensed under Sustainable Use License. Low-code workflow automation with 400+ integrations and AI
The project focuses on automation, workflow, no-code use cases and operates as an autonomous system that can plan and execute multi-step tasks with minimal human intervention.
Source code is available at github.com/n8n-io/n8n. With 193k+ GitHub stars, it ranks among the most battle-tested open-source tools in this space—meaning most common use cases are well-documented with community solutions available.
n8n is the best self-hostable alternative to Zapier/Make. The code node (JavaScript) makes it significantly more powerful than no-code alternatives for complex transformations. The LLM/AI integration has matured considerably — you can now build sophisticated RAG pipelines and AI agents visually. For teams that want workflow automation without handing all data to a cloud service, n8n is the answer.

Who Should Use n8n? 谁适合使用 n8n？
✓ Good Fit For适合以下场景
- Product and data teams who need to visually manage multi-step AI pipelines
- Organizations that want non-engineers to be able to maintain and modify AI workflows
- Non-technical business users who need to build AI workflows without writing code
- Rapid prototyping phases where you want to test AI logic before committing to engineering
✕ Not Ideal For不适合以下场景
- Simple single-step LLM calls (introducing a workflow engine is over-engineering)
- Engineering teams requiring deep API customization or complex integration logic (no-code platforms have hard ceilings)
Pros & Cons 优缺点
✓ Pros优点
- Visual workflow builder with 400+ integrations (Slack, GitHub, Notion, etc.)
- Self-hostable: run on your own server, Docker, or n8n Cloud
- Built-in AI agent nodes for LLM-powered automation workflows
- Code node allows custom JavaScript/Python for complex logic
✕ Cons缺点
- Sustainable Use License restricts certain commercial use cases
- Complex workflows can become hard to debug without good logging
