Our take
Pick Dify if product and applied-AI teams who want a visual RAG/agent studio and may later self-host. Pick StackAI if ops and IT teams who will burn Free’s 500 runs on two projects and then talk to sales for Enterprise seats, SSO, and on-prem — there is no public mid-tier dollar card. Skip Dify if someone who only wants ChatGPT, or an engineer who prefers a code-first graph (LangChain) with no studio.
