Our take
Pick Dify if product and applied-AI teams who want a visual RAG/agent studio and may later self-host. Pick FastGPT if chinese/English teams who will self-host a knowledge assistant and already have a model key. Skip Dify if someone who only wants ChatGPT, or an engineer who prefers a code-first graph (LangChain) with no studio. Skip FastGPT if people who want an English-only hosted studio with a printed card (Dify)
