Hi,
I purchased the TIER 4 plan, I sent an email to ask how to use AgenticFlow in my business, I hope to have an answer.

Referring to this article:
https://www.rivista.ai/2025/06/01/n8n-vs-langgraph/

I ask you:

1 - How do you compare with LangGraph (and LangChain) in terms of operation and results?
2 - Yesterday I was about to purchase a VPS hosting with N8N already installed, I stopped because I seem to have understood that AgenticFlow does not communicate with N8N. How do you compare with N8N?
3- Does it make sense to purchase VPS hosting with N8N, after purchasing AgenticFlow Tier 4 and considering that I would purchase the Multi-Agent option?
4 - Referring to the article above, will AgenticFlow, N8N and in ghenere other agents work in synergy or will they be competitors and alternatives?
Thanks
