Dify

Dify is a platform for developing language-model applications: a visual workflow editor, a RAG engine with knowledge base, an agent system and an extension marketplace let you build an assistant, a document chatbot or batch processing, then publish as a web app or API. Its place in this comparison is unique: where Zapier, Make or n8n orchestrate SaaS, Dify orchestrates models and knowledge. The cloud offering starts with a free sandbox with 200 message credits, 1 member, 5 applications and 50 knowledge documents. Professional costs 590 USD per year per workspace with 5,000 message credits monthly and 3 members; Team is 1,590 USD per year with 10,000 credits and 50 members. An Enterprise offer is on request.

Dify's Community edition is freely downloadable and deploys with Docker under an Apache-2.0-derived license: this is the deciding argument against cloud platforms, as documents and exchanges can stay on a European infrastructure you control. The interface is offered in English, Chinese, Japanese and Korean, but not French. The publisher displays GDPR compliance plus SOC 2 Type II and ISO 27001 certifications, with single sign-on, fine role management and audit logs on Enterprise. Each published app exposes a documented API. Limits are technical: self-hosting requires container and vector database skills, true model costs stack on top of subscription when using your own keys, and the workflow engine demands understanding RAG and agent concepts.
