AI Workflow Platform Comparison — Dify, FastGPT, RAGFlow

• For simple, fixed needs, calling the LLM API with an appropriate programming language is sufficient.
• Developers learning AI should consider self-implementation, as the principles remain constant regardless of the framework.
• Workflow and Extensibility focused ➔ Dify
• Knowledge Base focused ➔ RAGFlow

Background

Current workflow platforms are broadly categorized into two types:

1. Web-based workflow type, represented by Coze.
2. Code-based framework type, represented by LangChain and LlamaIndex.

This article compares WebUI-based workflow platforms such as Dify, FastGPT, and RAGFlow.
