Dify

Dify is an agent and workflow builder from LangGenius with MCP server support. On dify.ai/pricing, checked 31 October 2026, the Sandbox plan is free with 200 message credits, one workspace, one member, five apps and fifty knowledge documents. Paid plans are billed per workspace: Professional at $590 a year with 5,000 message credits a month, and Team at $1,590 a year with 10,000 credits a month. Credits cover model calls on OpenAI, Anthropic, Gemini, xAI and Tongyi until you switch to your own key. We would suggest it to teams who want a hosted builder for chat apps and RAG, with a free tier to try it. The main limits are the small free quota, the per-workspace pricing that suits one team more than many, and the licence, which our data lists as other rather than a standard open-source licence, so read the terms before self-hosting. We have not run it ourselves.
